Generation principle
The myocardial cell membrane is a semi permeable membrane. In a resting state, a certain number of positively charged cations are arranged outside the membrane, while the same number of negatively charged anions are arranged inside the membrane. The potential outside the membrane is higher than inside the membrane, which is called a polarized state. In a resting state, due to the polarization of myocardial cells in various parts of the heart, 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. When myocardial cells are stimulated with a certain intensity, the permeability of the cell membrane changes, and a large number of cations rush into the membrane in a short period of time, causing the potential inside the membrane to change from negative to positive. This process is called depolarization. For the whole heart, the potential changes in the process of the sequential depolarization of myocardial cells from endocardium to epicardium are called depolarization waves, which are the P waves of the atrium and QRS waves of the ventricle on the body surface electrocardiogram. After cell depolarization, a large number of cations are discharged from the cell membrane, making the potential inside the membrane change from positive to negative, and return to the original polarization state. This process is carried out from the epicardium to the endocardium, which is called repolarization. The potential changes during the process of myocardial cell repolarization are recorded by a current recorder and are called repolarization waves. Due to the relatively slow repolarization process, the repolarization wave is lower than the depolarization wave. The repolarization wave of the atrium is low and buried in the depolarization wave of the ventricle, making it difficult to recognize the surface electrocardiogram. The repolarization wave of the ventricle appears as a T-wave on the surface electrocardiogram. After all the myocardial cells were repolarized, they returned to polarization again, and there was no potential difference between the myocardial cells in different parts. An equipotential line was recorded on the body surface electrocardiogram.
