Contribution of Electrical Heterogeneity of Repolarization to the ECGients within ventricular myocardium and a third to voltage gradients between the ventricular myocardium and the His-Purkinje system. An understanding of the ECG clearly requires that we have an understanding of the electrical heterogeneity that exists within the heart, which we review briefly below

Several techniques were used to measure duration and disparity of repolarization such as body surface mapping ., endocardial monophasic action potential recordings ., and epicardial

The rapid upstroke of the action potential (phase 0) is caused by a large inward current through voltage-gated Na. channels, and is followed by a transient repolarization (phase 1), reflecting Na. channel inactivation and the activation of voltage-gated outward K. currents (Fig. 1).

Repolarization forces play a determining role in the normal function of the myocardium and when defective are often responsible for the development of life-threatening arrhythmias. Thus, our understanding of the electrocardiographic representation of the electrical activity of the he
