Therefore we selected the following biomarkers from the 12-lead ECG (QRS duration, QT dispersion, T wave amplitude, T peak to T end duration, and JT interval), the pressure-volume relationship (left ...

This may augment transmural heterogeneity of repolarization intrinsic to ventricular myocardium and, as a consequence, prolong the QT and JT intervals on the electrocardiogram (ECG).

Ventricular repolarization time (ECG QT and JT intervals) is associated with malignant arrhythmia. Genome‐wide association studies have identified 230 independent loci for QT and JT; however, 50% of ...

The following morning, nausea prompted her nurse to request antiemetic medications. You inspect the admission electrocardiogram (ECG) (Figure 1). Are QT-prolonging antiemetics safe to administer? In ...

Background: ECG markers of ventricular depolarization and repolarization are associated with an increased risk of arrhythmia and sudden cardiac death. Our prior work indicated lower serum calcium ...

QT maximum was measured from the earliest deflection of the QRS complex to the latest termination of T-wave among leads II, V2, and V5. Bazett’s formula was also used for correction of other ...

The coefficient λ characterizes the profile of the Tpe/RR hysteresis, i.e., the speed with which Tpe interval adapts to changing heart rate. While subject-specific optimization of the coefficient λ is ...

An EKG test can cost between $30 and $100 if covered by insurance, and much more if not. A normal physical might cost just $15 . That can just be the beginning.

Myocardial infarct cause myocardial tissue disease increasing the probability to have arrhythmias such as ventricular fibrillation, these cardiac problems are cause of death. This paper implement a ...
