The LVP Programming System
About the LVP Programming System
The LVP Programming System encompasses the software and hardware components
needed to program the LVP-1000 transmitter. The hardware components are connected
to a computer that has the LVP Program Utility installed.
Remote

Data Monitor
Computer
with LVP
Program
Utility
The LVP Programming System consists of the following components:
LVP Program Utility
The LVP Program Utility is a simple software program installed on a computer. The LVP
Program Utility allows you to read and change the data transmission schedule for your
LVP-1000 transmitters. It also keeps a log of all of the LVP-1000s and the configurations
you have programmed.
Remote Transceiver - Model XC-1000
The Remote Transceiver sends and receives programming signals to and from the
implanted transmitter.
Data Monitor - Model DM-1000
The Data Monitor converts the programming signals received from the Remote
Transceiver into a digital format and provides feedback about system operation via the
front panel display. The Data Monitor is connected to a serial port on the computer.
The LVP Programming System
Data Monitor Power Supply
The Data Monitor power supply provides power to the Data Monitor and Remote
Transceiver.
Magnet
The magnet manually activates the LVP-1000 transmitter during programming. It
also can be used to manually initiate a data transmission to the Dataquest A.R.T.
System. Keep the magnet in a convenient storage location so it is readily
accessible and to prevent inadvertent activation of the LVP-1000.
About the LVP-1000
The LVP-1000 measures left ventricular (LV) pressure and temperature from laboratory
animals. The LVP-1000 was originally developed for human clinical use, and provides
high fidelity left ventricular pressure measurements. It is ideal for cardiac-specific
applications such as congestive heart failure models where highly accurate parameters
of heart function are required.
Remote Sensor
Assembly (RSA)
Transmitter
Multi-Conductor Leads
There are 2 models of this transmitter, the LVP-1000-433, which is sold for use in
Europe; and the LVP-1000-916, which is sold for use in the United States and Canada.
Both models are used and function in the same manner, except for the radio
transmission frequency. In DSI manuals and product literature, the shortened model
name, LVP-1000, refers to both models.
The LVP-1000 is the first in a series of future generation transmitters providing
automated configuration, confirmation of transmitter ID, and programmed Duty-Cycling
The LVP Programming System
to extend battery life. The LVP-1000 uses an extremely stable pressure sensor located
in the Remote Sensor Assembly (RSA) to minimize pressure drift over extended implant
durations. The RSA is located separate from the Transmitter to minimize the effects of
fluid head pressure. The RSA and Transmitter are permanently connected via two MultiConductor Leads.

About the Data Monitor
The Data Monitor, DM-1000, is a component of the LVP Programming System's
hardware. The Data Monitor is connected to a serial port on the computer. It must also
be connected to the power supply provided, which must be plugged into an electrical
outlet. The Remote Transceiver, XC-1000, is connected to the Data Monitor.
Front of the Data Monitor
Back of the Data Monitor
Status Lights
The front of the Data Monitor has several status lights and a Transfer button. In general,
these lights are not used with the LVP Programming system. Here is a brief explanation
of these status lights.
• The 'Ready' light will be solidly illuminated when the LVP Program Utility is in
use.
• At all other times, the 'Ready' light will flash when the Data Monitor is receiving
power.
• All other lights may be illuminated or flash temporarily when the Data Monitor is
first powered up and when the LVP Program Utility is opened. These flashes do
not indicate any problem or condition.
• The 'Transfer' button does not perform any function in the LVP Programming
System.
Note
•
You will not be able to use the Program Wizard of the LVP Program Utility
if all of the LVP Programming System's hardware is not connected to the
computer.
•
Always disconnect the Data Monitor from your computer or disconnect
the Data Monitor power supply before starting your computer. Reconnect
the hardware after the computer fully boots. If it is connected when your
computer boots, the Windows operating system may mistakenly
recognize it as mouse. You will notice your mouse pointer moving
randomly around the screen, not under the control of your mouse. If this
occurs, simply disconnect the Data Monitor.
The LVP Programming System
About the Remote Transceiver
The Remote Transceiver, XC-1000, is a component of the LVP Programming System's
hardware.
The Remote Transceiver is connected to the back of the Data Monitor. It is used to send
and receive programming signals from the LVP-1000 during programming.
The Remote Transceiver has a red-colored circle on the front label. When programming,
hold the circle directly over the LVP-1000 transmitter. (see figure below).
The LVP Programming System
The Remote Transceiver should be held within 2 inches of the LVP-1000 during

Programming the LVP-1000
Programming the LVP-1000
Using the Program Wizard
The Program Wizard allows you to define the LVP-1000 transmission schedule and
settings.
Consider the following when using the Program Wizard:
• You must have the LVP Programming System hardware connected to your
computer to start the Program Wizard. The Data Monitor, Remote Transceiver,
and power supply must all be correctly connected.
• Animals may be implanted with both an LVP-1000 and another DSI transmitter
model, such as a D70-PCT. In this case, turn off the second transmitter before
attempting to program the LVP-1000.
• Do not try to collect data from the LVP-1000 using Dataquest A.R.T.™ during
programming. Before starting the LVP Program Utility, stop sampling from all
LVP-1000 devices in Dataquest A.R.T.™
• Determine how you wish to program the LVP-1000 for your studies, depending
on how you wish to collect data. See Choosing the Transmission Schedule for
more information on the differences between the transmission schedules.
• The LVP-1000 will retain this transmission schedule until it is reprogrammed with
different settings.
Choosing the Transmission Schedule
The LVP-1000 can be programmed for one of three modes of transmission: Manual
Transmission, Continuous Transmission, or Automatic (duty-cycle) Transmission. These
each have different benefits and uses.
Manual Transmission
•
•
•
•
•
•
The LVP-1000 must be activated with a magnet to collect a data transmission.
The LVP-1000 is OFF unless activated.
The transmission length is programmed to a discreet length.
The LVP-1000 will turn OFF when the transmission is complete.
Use this mode when the animal is not actively being studied.
Use the Duty-cycle sampling mode in Dataquest A.R.T.
Continuous Transmission
•
•
•
•
•
•
•
14
The LVP-1000 can continuously transmit data in this mode.
After programming, the LVP-1000 is turned OFF. Turn it ON by activating with
the magnet.
When ON, the LVP-1000 will transmit until you use a magnet to turn it OFF. (This
is similar to other DSI transmitters.) When OFF the LVP-1000 will not transmit
until you use a magnet to turn it ON.
A transmission length is not selected.
The LVP-1000 must be reprogrammed to stop data transmissions.
Use either Continuous or Scheduled sampling modes in Dataquest A.R.T.
This mode uses the most battery power: the battery will last 6 weeks in this
mode.
Programming the LVP-1000
Automatic (Duty-Cycle) Transmission
•
•
•
•
•
•
•
The LVP-1000 transmits data according to the programmed schedule.
The LVP-1000 automatically turns ON and transmits for the programmed
transmission length. It is OFF at all other times.
A magnet can be used to activate the LVP-1000 to collect a transmission when it
is OFF.
The LVP-1000 can be programmed to transmit only during certain parts of the
day, using a Start and End time; or to transmit periodically 24 hours a day.
The transmission length is programmed to a discreet length. All transmissions
will be this length.
Use the Duty-cycle sampling mode in Dataquest A.R.T.
The battery life will depend on the transmission schedule. The battery can last for
over 2 years in this mode.
Programming the LVP-1000
The Program Wizard allows you to set the LVP-1000 transmission schedule and
configuration settings. The Program Wizard guides you through the following
programming procedures.
1. Starting the Wizard and reading the current configuration

This action automatically identifies new generation hardware (Data Exchange
Matrices, APR-1, RPC-1, RMC-1, RMC-1HF, RMC-433, and RMC-916). It will
also check for signal calibrations.
The Hardware - Verify action runs automatically the very first time you open a
configuration and can perform much of the maintenance by recognizing the
hardware connection locations.
If a Data Exchange Matrix or new generation receiver is moved or disconnected,
all of the associated configuration items are moved or disconnected with it.
When new generation hardware is disconnected, all devices and associated
configuration information in the database will be moved into the Recycle Bin
located on the Configuration window for retrieval.
Old generation hardware is not automatically moved.
Data Collection*
Selecting a Sampling Protocol in Dataquest A.R.T.
There are two ways to sample data: continuously or on a schedule. Both types of
sampling require an understanding of sampling slots - see your Dataquest A.R.T.
manual for more information on sampling slots.
Each type of sampling method is described here. For more information on a specific step
see the following headings.
Duty-Cycle Sampling
Duty-cycled sampling is for use with LVP-1000 transmitters. However, additional
PhysioTel transmitters can also be sampled using duty-cycle sampling if they are
grouped with an LVP-1000 transmitter. Each duty-cycled animal fills a sampling slot
until its sampling is turned off by the user. An LVP-1000 should be programmed to
enable automatic transmissions.
Perform the following steps for duty-cycle sampling

Dataquest A.R.T. and the LVP-1000
Continuous Sampling
Continuous sampling is just what the name implies - sampling one or more transmitters
for an extended period without breaks in the data. A user manually starts continuous
sampling, and it continues uninterrupted for minutes, hours, or days until a user stops
the process. Each animal that is sampled continuously will fill a sampling slot until its
sampling is terminated by the user. An LVP-1000 should be programmed to transmit
continuously for continuous sampling.

Scheduled Sampling
Scheduled sampling allows the sampling of many transmitters sequentially and at
intervals defined by the user in the Acquisition software. Each animal that is sampled on
a schedule will fill a sampling slot only during its scheduled time of sampling. An LVP1000 should be programmed to transmit continuously for scheduled sampling.

•
DSI recommends increasing the maximum file size if collecting waveform data
continuously over a long period of time.
Make sure that your back up method (floppy disk, Zip disk, CD, DVD, network,
etc.) can accommodate the size of your individual data files.
Selecting Data Types to Collect
After creating a configuration and study folders, select the data types to collect from
each animal. Designate which parameters and waveforms you wish to collect from each
animal, by marking them online. Parameters and waveforms for each animal need to be
marked online in order to be collected.
To select data types to collect
1. From the Acquisition window, select an animal. Double click on the animal icon
to display the Source Settings window.

Segment Duration - Enter a value of 1 to 300 seconds to specify the length of
the scheduled sample. This value is used to break continuous sampling into
contiguous segments for parameter extracting, browsing, and analysis. If using
an LVP-1000 transmitter, the segment duration must be less than or equal to the
length.
Waveforms - Click each of the waveform check boxes to select them as online
for sampling. A check mark indicates waveforms for this data signal will be
sampled and saved to the designated study folder.
Parameters - Click on each of the parameter check boxes to select them as
online for sampling. A check mark indicates parameters for this data signal will
be sampled and saved to the designated study folder.
Schedule

To start duty-cycled sampling of an LVP-1000 and another transmitter
A PhysioTel transmitter (non-LVP-1000) can be selected to sample at the same time as
an LVP-1000 that is transmitting in Duty-cycle mode. For example, this is useful if an
animal is implanted with both an LVP-1000 and a D70-PCTP transmitter.
1. Set both animal IDs to the same group and priority number.
To set priority and group
From the Acquisition window, select the animal icon, right click, and
choose Set Priority. The Set Priority window appears.
Assign priority and group to the selected animal icon.
• Level – The priority level, with 99 being the highest priority.

a priority of 99 before an animal with a priority of 98 or 97.
• Group – Forces all sources with the same priority to be
sampled together. For example, all sources with 99 are sampled
together, if possible. Click this box to place a checkmark in it and
identify this animal as a member of a group. This is typically
used to ensure simultaneous scheduled sampling of related
sources such as a TA11PA-C40 transmitter and a flow probe
converter.

Pressure immediately before ventricular
contraction.
Pressure over time at fixed pressure
relative to diastolic pressure value.
Default pressure value = 40mmHg.
Pressure over time at fixed pressure
relative to diastolic pressure value.
Default pressure value = 60mmHg.
Pressure over time at fixed pressure
relative to diastolic pressure value.
Default pressure value = 80mmHg.
The maximum change in pressure over
time divided by the pressure at that
point (max dP/dt)/P. P is defined as the
absolute pressure minus end diastolic
pressure.
Estimated systemic diastolic pressure.
This is the pressure at the point of max
dP/dt, sometimes referred to as
P@maxdP/dt. This should reflect the
point where the valve opens in the left
ventricle of the heart.
Mean pressure is calculated based on
averaging the pressure over 20 subsegments of the segment length. The
default reduced mean calculation
discards outliers in the sub-segments in
the calculation.
Peak pressure after detected max
dP/dt.
Maximum change in pressure over time
between any two sample points on the
rising edge of a pressure cycle.
Maximum negative change in pressure
over time between any two sample
points on the falling edge of a pressure
cycle.
The relaxation time constant from min
dP/dt to the point where the pressure
has dropped 66% of the distance from
systolic to diastolic pressure.
This is the extrapolation of dP/dt vs
pressure extrapolated back to P=0. This
is the contractility of the heart
unaffected by loading.

Cause: The software was unable to open the Log Viewer in Internet Explorer.
Solution: Disconnect the Data Monitor power supply and reboot the computer.
Reconnect the power supply and retry.
If the problem persists, the software should be re-installed. You may save the log.xml file
to a new location prior to the re-installation, and copy it into the LVP Program Utility
folder after the installation. This will preserve the log file. Contact DSI Technical Services
if you are uncomfortable performing this procedure without assistance.
Unexpected exception. Please restart the software.
Cause: An internal error has occurred in the software.
Solution: Close the software and restart. If this does not solve the problem, disconnect
the Data Monitor power supply and reboot the computer. Reconnect the power supply
and retry. If the problem persists, contact DSI Technical Services.
Errors associated with firmware files

continuous: A transmission setting of the LVP-1000. The LVP-1000 is always sending
telemetry data in this setting. Using this setting uses the most battery power.
Data Monitor: Hardware that converts the data received from the remote transceiver
into a digital format and transfers the data to the computer. The Data Monitor is
connected to the computer via a serial port.
duty-cycle: A transmission setting for the LVP-1000. The LVP-1000 follows a schedule
to automatically turn on, measure the LV Pressure and transmit the data to the
receiver. Can occur once or multiple times per day. This mode consumes the
least battery power, but consumption will depend on the schedule selected.
end diastolic pressure (LVEDP): End of the diastolic period and start of the systolic
period, typically characterized by a sharp upturn in pressure, before the climb to
LVSP through max LV dP/dt.
left ventricle (LV): The chamber on the left side of the heart that receives arterial blood
from the left atrium and pumps it into the aorta.
Left Ventricular Pressure (LVP): Blood pressure measured in the heart's left ventricle.
The LVP-1000 catheter is inserted through the ventricle wall into the LV.
log: See system log.
LV: Left ventricle
LVP: see Left Ventricular Pressure
LVP-1000: Implanted telemetry transmitter that measures the LV pressure and transmits
the pressure data to the Dataquest system using a radio telemetry signal. It has
two main parts: the Remote Sensor Assembly (RSA) and the Telemetry Unit
(TU), connected by Multi-conductor leads.
max LV -dP/dt: The maximum negative derivative (dP/dt) value between LVSP and
LVBDP of the following cycle that is calculated using 2 or more data points.
max LV +dP/dt: The maximum positive derivative (dP/dt) value between LVEDP and
LVSP that is calculated using 2 or more adjacent data points.
mean diastolic pressure (LVMDP): The average of the LV pressure waveform between
and including LVBDP and LVEDP.
Multi-Conductor Lead: Connects the Remote Sensor Assembly to the transmitter of the
LVP-1000

Program wizard: The Program wizard allows you to set the LVP-1000 transmission
schedule and configuration settings.
Remote Sensor Assembly: Part of the LVP-1000. It is comprised of the Pressure
Transmitting Catheter and pressure sensor. It is surgically attached to the
epicardium by the suture skirt.
Remote Transceiver: A device that sends and receives programming signals to and
from the implanted LVP-1000 and is connected to the Data Monitor.
RSA: see Remote Sensor Assembly
serial port: A connection interface on the computer. It has 9 pins organized in 2 rows
and usually located on the back of the computer. Some computers may have
more than one serial port.
system log: The record of all LVP Program Utility attempts to program LVP-1000
transmitters. It also records the configurations programmed.
systolic pressure (LVSP): End of the systolic period, determined by a maximum
pressure value.
telemetry data: Data that is collected by the LVP-1000 and transmitted to the Dataquest
System receiver via radio signals.
Telemetry Unit: Refers to the transmitter portion of the LVP-1000. See transmitter for
more details.
transmission: A telemetry data communication from the LVP-1000.
transmission length: The period of time that a transmission will last. All transmissions,
both scheduled and manual, will last this period of time. Use the Program Wizard
to set the transmission length.
transmitter: Part of the LVP-1000. It transmits the telemetry data to the receiver. It also
sends and receives programming information from the Remote Transceiver. The
transmitter is implanted in a subcutaneous pocket and is connected to the
Remote Sensor Assembly via two Multi-Conductor leads.
wizard: Refers to an interactive utility that guides you through a particular task . The
Program Wizard is the only wizard in the LVP Program Utility.
