During this phase, the transmembrane action potential repolarizes from its plateau voltage of
approximately 10 to 10 mV to its resting level of approximately 85 mV. The interventricular …

Objectives: Our objective in this study was to evaluate Tpeak-Tend interval (Tp-e) and other
electrocardiographic parameters as risk factors for recurrence of life-threatening cardiac …

QT dispersion was originally proposed to measure spatial dispersion of ventricular recovery
times. Later, it was shown that QT dispersion does not directly reflect the dispersion of …

The article reports that adverse reactions to drug therapy are the bane of the practitioner and
all the more so when they occur in an idiosyncratic or apparently unpredictable, fashion. At …

Sudden cardiac death, frequently due to ventricular arrhythmias, is a significant problem
globally. Most affected individuals do not arrive at hospital in time for medical treatment …

Death in chronic heart failure (CHF) can be from progression of disease or sudden and
unexpected. We have attempted to identify factors that predict sudden death in CHF. We …

Background Dilated cardiomyopathy (DCM) is associated with a high incidence of malignant
ventricular arrhythmias and sudden death. Abnormalities in repolarization of ventricular …

Background Sudden unexplained death in psychiatric patients may be due to drug-induced
arrhythmia, of which lengthening of the rate-corrected QT interval (QTc) on the …
