title: Repolarization gradients derived by subtraction of monophasic action potential recordings in the human heart. Studies incorporating altered mechanical loading and ischemia.
abstract: 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.
