Introduction
Chapter 2 Introduction
SE-1010 PC ECG has similar functions with an ordinary electrocardiograph. ECG data can be
sampled, analyzed and stored in a PC, and it can be saved in PDF, Word, BMP or JPG format.
ECG waves can be frozen and reviewed. Auto measurement and diagnosis are available, and the
diagnosis template can be edited. SE-1010 PC ECG can also be invocated by Smart ECG Net
version 1.3 or above.
When a patient with coronary heart disease runs, the added heart load will cause myocardium
hypotension, and then the ECG will change abnormally. Therefore, with the function of exercise
ECG, SE-1010 PC ECG can also be used to diagnose concealed coronary heart disease and
atypical angina pectoris, prescribe the workload for patients with myocardial infarction before
they leave hospital, and assess the effect of the treatment. With SE-1010 PC ECG, doctors’
workload can be reduced greatly.
NOTE:
1. The exercise ECG function is optional. It is available only if you purchased this
function.
2. The pictures and windows in this manual are for reference only.

Preparations Before Operation
Chapter 5 Preparations Before Operation
5.1 Preparing the Patient
5.1.1 Instructing the Patient
Before attaching the electrodes, greet the patient and explain the procedure. Explaining the
procedure decreases the patient’s anxiety. Reassure the patient that the procedure is painless.
Privacy is important for relaxation. When possible, prepare the patient in a quiet room or area
where others can’t see the patient. Make sure that the patient is comfortable. The more relaxed
the patient is, the less the ECG will be affected by noise.
5.1.2 Preparing the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and
frequently creates artifacts that distort the ECG signals. By performing methodical skin
preparation, you can greatly reduce the possibility of noise caused by muscle tremor and baseline
drift, ensuring high-quality ECG waves. There is natural resistance on the skin surface due to dry,
dead epidermal cells, oils and dirt.
To prepare the skin
1.
Shave hair from electrode sites, if necessary. Excessive hair prevents a good connection.
2.
Wash the area thoroughly with soap and water.
3.
Dry the skin to increase capillary blood flow and to remove the dead, dry skin cells and oils.
4.
Use the disposable frosting film in the standard accessory list to get good ECG waveform.
NOTE: Rub the skin with a gauze pad to increase capillary blood flow if you don’t operate
the steps above.

6.6.4 Analyzing High Frequency ECG
In a conventional electrocardiogram, only these ECG signals, of which the amplitude is in the
millivolt range and the frequency is less than 100 Hz, are visible. Those ECG signals, of which
the amplitude is in the microvolt range and the frequency is between 150Hz and 250Hz, are
invisible. If these invisible high frequency components are abnormal, it is the indication of
myocardial ischemia or myocardial infarction.
HF ECG is to detect high frequency components of QRS such as notches, slurs and beadings.
