CARDIONET: MOBILE CARDIAC OUTPATIENT TELEMETRY
CardioNet developed and introduced a new, integrated technology and service – Mobile Cardiac
Outpatient Telemetry – which allows heartbeat-by-heartbeat ECG monitoring, analysis and
response, at home or away, 24/7/365.
CardioNet’s Mobile Cardiac Outpatient Telemetry (MCOT) assists physicians in the diagnosis
and management of difficult-to-diagnose arrhythmias. Given the infrequent and asymptomatic
nature of some arrhythmias, it is often challenging to capture an event with conventional
monitoring technology, such as Holter and cardiac event monitoring.
The CardioNet System detects and transmits both symptomatic and asymptomatic
arrhythmias, based on monitoring parameters defined by the prescribing physician. Patients
are not required to sense or transmit events. However, if patients feel symptoms they can use
the touch screen on the CardioNet monitor to enter their symptoms and activity level, which
are transmitted to the CardioNet Monitoring Center along with their ECG. The physician
receives a daily telemetry report containing a representative ECG strip of the events detected;
a time and date stamp of the event, including any reported symptoms and activity.
The CardioNet device retains up to 720 hours of ECG data on each patient, allowing
physicians to request additional data through “fetch” requests to the CardioNet Monitoring
Center.
CardioNet MCOT offers physicians a powerful new diagnostic and patient management tool for
a wide range of monitoring indications.

TECHNOLOGY OVERVIEW
CardioNet integrates patient monitoring, wireless communications technology, and the Internet
to allow cardiac rhythm related problems to be quickly identified, quantified, and treated.
The CardioNet System is comprised of a sensor with three leadwires, a monitor, and base.
The lightweight sensor (invisible under clothing) is worn by the patient. It continuously records
and analyses two channels of ECG and transmits the ECG by a radio frequency (RF) link to
the monitor.
The monitor is approximately the size of a PDA device. It has a powerful microprocessor,
extensive memory, embedded algorithm, LCD display, and wireless modem. The monitor is
powered by a rechargeable lithium battery, which powers the monitor for at least 10 hours.
The C5 monitor’s microprocessor is programmed with an algorithm that identifies arrhythmias
according to parameters selected by the prescribing physician. The standard algorithm
detection parameters and physician notification criteria established by CardioNet’s Medical
Advisory Board can be individualized for each patient, practice and physician.
The sensor continuously acquires the patient’s ECG in real time, and regularly transmits this
information to the monitor. When an abnormal rhythm has been identified or when the patient
enters a symptom, the data is transmitted to the CardioNet Monitoring Center for review,
interpretation and response by a certified monitoring specialist.
When the patient is at home and base is in use, the patient’s telephone line may be used to
transmit the data. Cellular communication is the primary means used to transmit events. If an
event occurs when the patient is in an area where cellular coverage is inadequate, the monitor
stores the data and transmits the event when the patient has moved into an area with cellular
coverage – or uses regular telephone lines to transmit the event once the monitor can
communicate with the base.
The CardioNet C5 Monitor stores a minimum of 30 days of the patient’s ECG data. Physicians
can request that CardioNet “fetch” additional data, beyond that contained in the Telemetry
Reports, by contacting the CardioNet Monitoring Center.
Page6of17
SERVICE OVERVIEW
First, the prescribing physician is registered in the CardioNet service. All applicable contact
and demographic data is collected and entered into the CardioNet Patient Enrollment and
Management System (PEMS) by a CardioNet representative. When a physician identifies a
patient who is appropriate for CardioNet services, the practice faxes a Patient
Prescription/Order form to CardioNet along with the patient insurance information.
Important Information: Urgent Events
CardioNet is not an emergency response service. If patients experience symptoms that concern
them, they should seek medical help.
In the course of monitoring a patient’s heart, CardioNet may detect cardiac events which are
potentially life-threatening and which were not anticipated by the patient’s physician. As directed
in the Physician Notification Criteria, CardioNet will attempt to contact the physician and patient
if ordered.
CardioNet’s ability to obtain information regarding a cardiac event and to contact a patient or
his/her physician in a timely manner is limited by a number of factors, including:
• Transmission of information about a cardiac event to
CardioNet‘s monitoring center is potentially limited by the
availability of standard telephone lines and/or cellular phone
coverage
• There is an inherent time delay from the time that an event is
detected to when the events are analyzed and confirmed by a
certified cardiac technician (“CCT”)
• There is an inherent time delay from when the event is
analyzed and confirmed by the CCT to when CardioNet is able
to make contact with the patient or his/her physician
• If a patient or physician is not accessible by telephone,
CardioNet will not succeed in making contact with them
When CardioNet does detect a potentially serious cardiac event as defined by the patient’s
physician, we will attempt to contact the patient’s physician for direction. CardioNet will also
attempt to contact the patient and inform him/her of a cardiac event that has been received that
requires evaluation in the emergency room, per the physician’s notification criteria. The patient
may decide to seek medical help by calling EMS directly or the patient may ask that CardioNet
assist them in contacting EMS.
In all cases, due to the limitations of the CardioNet service as described above, patients should
not delay seeking medical help if they experience symptoms that concern them and are so
instructed in the Patient Education Guide. Also, patients are instructed in the Patient Education
Guide not to rely on CardioNet as an emergency response service.

PHYSICIAN REPORTS
Three types of reports may be issued to physicians during monitoring:
• Daily Telemetry Reports: sent every 24 hours for all patients, which contains sample strips
of arrhythmias detected and patient-reported symptoms, heart rate and AF frequency and
duration data.
• Urgent Reports: issued when an event occurs that the physician has defined as urgent.
• Summary Reports: Provides a summary of all billable days of service.
Physician reports are available by fax or through PEMS, CardioNet’s Internet-based patient
management system. For information or in-service on PEMS, please contact your CardioNet
Account Representative.
The CardioNet Monitoring Center is staffed with highly qualified and experienced cardiac
monitoring specialists. At a minimum, all monitoring specialists are CCT certified. They have
experience in cardiovascular monitoring, hospital based C.C.U. and I.C.U. telemetry, and/ or
emergency medical services.
As a Medicare provider, CardioNet is licensed as an Independent Diagnostic Testing Facility
(IDTF).
The CardioNet monitoring specialists serve a vital role in continuously analyzing and
responding to arrhythmic events. The monitoring specialists provide a thorough preliminary
analysis of the patient’s ECG to insure that the initial interpretation is accurate and presented in
the appropriate time and manner as requested by the physician.
Calls may be monitored and recorded for quality assurance. CardioNet requires that all
monitoring specialists participate in additional training and educational programs. A
continuous QA process with independent oversight has been established for all facets of the
service center operation.
The monitoring specialists, based on defined physician guidelines, prepare Daily Telemetry
Reports for final physician review and interpretation.
The CardioNet Monitoring Center continuously analyzes events, responds appropriately, and
issues telemetry reports 24/7/365.

ARRHYTHIMIA DETECTION ALGORITHM PERFORMANCE ANALYSIS
The CardioNet C5 System incorporates an arrhythmia analysis algorithm whose performance
is presented below:
The algorithm results were obtained from the respective databases in strict accordance with EC-
57 and with 0% downtime on both databases.
Performance Measure MIT Arrhythmia Database AHA Database
Average QRS Detection
Sensitivity % 99.96 99.74
Average QRS Detection
Positive Predictivity % 99.83 99.83
The CardioNet C5 system does perform analysis of ST Segment changes. The ST Segment
analysis is done on all leads without any signal scaling or gain adjustment. There are no
operator selectable detection criteria for ST segment shifts.
The ST algorithm has been tested for accuracy of the ST segment data. The significance of the
ST segment changes need to be determined by a physician.
HEART RATE MEASUREMENT REPORT
The performance of the analysis algorithm for heart rate detection on standard databases is
shown below. The average RMS errors for the AHA, MIT-arrhythmia, and NST databases are
1.23%, 1.08%, and 15.84% respectively for the C5 product (model CN1006).
Sustained heart rate (SHR) is inversely proportional to the RR interval averaged over 10
seconds or 12 consecutive beats, whichever is shorter. The Heart Rate Trend Graph shows
SHR and its minimum and maximum values during that interval.

Use of CardioNet system with implanted pacemakers and ICDs (defibrillators)
If the patient has an implanted pacemaker or defibrillator (ICD), the manufacturer may have
recommended certain precautions when using a cellular phone. Since the CardioNet monitor
contains a cellular phone, the patient should take the same precautions when carrying and
using the monitor. In general, most manufacturers recommend the following:
• Keep a distance of at least six inches (15 cm) between the cellular phone and a pacemaker
or defibrillator.
• Hold the cellular phone on the opposite side of the body from the pacemaker or defi brillator.
• Don’t carry a cellular phone in a breast pocket or on a belt if that would place the phone
within six inches of the pacemaker or defibrillator
• Refer to the manufacturer’s information for guidance regarding your pacemaker or ICD and
possible interference issues.
