Repolarization gradients derived by subtraction of monophasic action potential recordings in the human heart. Studies incorporating altered mechanical loading and ischemia.
Information derived from the analysis of the electrocardiographic waveform remains one of the most valuable diagnostic aids in modern cardiology. Paradoxically, although changes in the ST-T segment probably have the widest clinical application, it is the analysis of this repolarization phase that has been surrounded by the greatest difficulties in interpretation.
