Proper measurement of the QT interval on the 12-lead body-surface ECG is challenging in
daily practice. Even more difficult is its correct estimation in the presence of repolarization …

QT interval prolongation is a known risk factor for development of malignant ventricular
arrhythmias. Measurement of the QT interval is difficult in the setting of ventricular pacing …

Интерпретация каждой электрокардиограммы должна включать измерение и оценку
интервала QT, как увеличение, так и уменьшение продолжительности которого …

Background Determination of the prolonged QT interval in left bundle branch block (LBBB),
which should be of special concern to identify individuals at high risk of potentially fatal …

Objectives To evaluate the predicative power of the electrical risk score (ERS), a

The dynamics of the collapse of complexity observable in the performance of the
cardiovascular system during the stress test is investigated in this paper. For this purpose …

Purpose/Background: Prolonged QT interval related to psychopharmacological treatment is

electrocardiogram when prescribing medications known to increase the risk of Torsades de …

Cardiotoxicity is a serious side effect of some common cancer treatments. Although the
cardiotoxic potential of anthracycline and trastuzumab is well known, many other …

Abstract Background and Aim Prolonging the QT interval in the right bundle branch block
(RBBB) can create challenges for electrophysiologists in estimating repolarization time and …
