The electrocardiogram function automatically records the bioelectric signal (ECG signal) generated by the heart muscle activation when the heart is active. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. Before the heart beats, the myocardium is excited first, and a weak current is generated during the excitation process, which is conducted to all parts of the body through the tissues. Since the tissues of each part of the body are different and the distance between each part and the heart is different, various parts of the body surface of the human body show different potential changes. The relationship between the surface potential generated by the electrical activity in the human heart and time is called Electrocardiogram. An electrocardiograph is an instrument that records these physiological electrical signals. 1 In China, it is generally divided into single-channel, three-channel, six-channel and twelve-channel electrocardiograph according to the number of synchronous output channels of the recorder.
