ECG is a technology that uses an electrocardiograph to record the changes in the electrical activity of the heart during each cardiac cycle from the body surface.
Features
Different channels available: 3-channel ECG, 6-channel ECG
7 inch color LED display
touch screen
Support SD card, USB disk
Support ECG analysis capability
Floating; Protection circuit against Defibrillator effect
The application scope of ECG
1. Record the electrical activity of the normal human heart.
2. Help diagnose arrhythmia.
3. Help diagnose myocardial ischemia, myocardial infarction and location.
4. Diagnose enlarged and thick heart.
5. Determine the effect of drugs or electrolytes on the heart.
6. Judge the artificial heart pacing status.

Principle of Production
The myocardial cell membrane is a semi-permeable membrane. In the resting state, a certain number of positively charged cations are arranged outside the membrane, and the same number of negatively charged anions are arranged inside the membrane. The external potential of the membrane is higher than the inside of the membrane, which is called the polarization state. In the resting state, since the myocardial cells in various parts of the heart are in a polarized state, there is no potential difference, and the potential curve recorded by the current recorder is flat, which is the equipotential line of the body surface electrocardiogram.
ECG lead connection
ECG vector axis
The measurement methods of the electrocardiogram axis mainly include the visual inspection method, the drawing method and the look-up table method. The heart is a three-dimensional structure composed of countless cardiomyocytes. During the depolarization and repolarization of the heart, many galvanic vectors in different directions are generated. Integrate the galvanic vectors in different directions into a vector to form the integrated ECG vector of the whole heart.
