The Effect of Heart Chronotropic Function on the Duration of ECG Intervals in Early Repolarization Syndrome (pp. 155-157)
Authors: T. Yu. Zotova and A. Yu. Ryabinina
Abstract: Early repolarization syndrome (ERS), according to recent studies, is associated with a risk of ventricular fibrillation and sudden cardiac death [1, 2]. Pathogenesis of ERS is considered to related to a conjugation failure of ion flow through the cell membrane of cardiomyocytes in the 3rd phase of action potentials. The cause of ERS is often autonomic dysfunction . In this regard, the actual goal of the research was to study the effect of the duration of the previous RR interval (ms) on the duration of QT (ms), ½T (descending segment (ms)), QT-½ T (ms) as a reflection of the effect of chronotropic heart function.
