The Effect of Exercise on the Timing of Aortic Valve Closure with Respect to the ECG Tracing
Author(s): Yurie Obata, Pavel Ruzankin, Allan Gottschalk, Dan E Berkowitz, Jochen Steppan and Viachaslau Barodka
Objective: The temporal relationship between electrical repolarization of the heart and mechanical relaxation is not well quantified. In this study we examined the timing of the aortic valve (AoV) closure with respect to the electrical repolarization at rest and following exercise in young healthy subjects.
Methods: We measured the period from the apex of the T wave (aT) to the beginning of the second heart sound (S2-aT) and the period from the apex of the T wave to the end of the T wave (eT-aT).
