摘要：
The heartbeat is recorded on an electro- cardiogram (ECG) as a characteristic trace determined by changes in the electrical activity of the heart muscle. The T wave is a component of this waveform that is associated with the repolarization phase of the action potentials1. It is asymmetrical in healthy subjects, but tends to become symmetrical with heart disease2. The reason for the T-wave shape is not clear3. Here we show that T waves become more symmetrical as a result of an increase in the dispersion of the regional repolarization of cardiac muscle.
