Ventricular gradient and nondipolar repolarization components increase at higher heart rate.
Differences in action potential duration reflect differences in ion channel properties. These properties also determine rate dependence of action potential duration, and transmural dispersion was confirmed experimentally to increase with cycle length. While several electrocardiographic indexes characterizing repolarization abnormalities have been proposed, studies of their heart rate dependence...
متن کاملDo ventricular repolarization interval ratios depend on heart rate and should they be rate-corrected?
QT interval decreases with increasing heart rate (HR), hence to define normal values of QT interval for different heart rates requires the application of a QT interval rate correction formula. However, it’s unknown the influence of HR on the ratios between several ventricular repolarization intervals, that can be useful as risk predictors of malignant ventricular arrhythmias. This study analyze...
متن کاملBeat-to-beat interplay of heart rate, ventricular depolarization, and repolarization.
To improve malignant arrhythmia risk stratification, the causal and random components of spatiotemporal dynamics of heart rate (RR distances), ventricular depolarization sequence, and repolarization disparity were studied based on body surface potential map records taken for 5 minutes, in resting, supine position on 14 healthy subjects (age range, 20-65 years) and on 6 arrhythmia patients (age ...
متن کاملShort-term effects of varenicline therapy on homogeneity of heart rate, atrioventricular conduction and ventricular repolarization
BaCKgRound: The effects of varenicline, an effective drug for smoking cessation, on atrioventricular and ventricular conductance remain unknown. oBjeCTive: To evaluate the effects of varenicline on heart rate, PR interval, QT interval and QT dispersion (QTd). MeTHodS: A total of 60 smokers were prospectively enrolled in the present study. Twelve-lead electrocardiogram recordings were obtained f...
متن کاملLeptin decreases heart rate associated with increased ventricular repolarization via its receptor.
Leptin has been proposed to modulate cardiac electrical properties via β-adrenergic receptor activation. The presence of leptin receptors and adipocytes in myocardium raised a question as to whether leptin can directly modulate cardiac electrical properties such as heart rate and QT interval via its receptor. In this work, the role of local direct actions of leptin on heart rate and ventricular...
