Diclofenac prolongs repolarization in ventricular muscle with impaired repolarization reserve. [PDF]
PLoS ONE, 2012 BACKGROUND: The aim of the present work was to characterize the electrophysiological effects of the non-steroidal anti-inflammatory drug diclofenac and to study the possible proarrhythmic potency of the drug in ventricular muscle.

Seasonal variations in ventricular repolarization and tachyarrhythmias in hibernating brown bears (Ursus arctos arctos) [PDF]
Physiological ReportsIn humans, hypothermia prolongs ventricular repolarization and associates with sustained ventricular tachyarrhythmias. In bears, body temperature drops during hibernation similar to moderate human hypothermia, yet they rarely face fatal outcomes during ...

Dispersion of ventricular repolarization: Temporal and spatial. [PDF]
World J Cardiol, 2020 Repolarization heterogeneity (RH) is an intrinsic property of ventricular myocardium and the reason for T-wave formation on electrocardiogram (ECG). Exceeding the physiologically based RH level is associated with appearance of life-threatening ventricular arrhythmias and sudden cardiac death.

J wave syndrome: Benign or malignant? [PDF]
ARYA Atherosclerosis, 2021 J wave syndrome is an electrical disease of the heart due to pathologic early repolarization. It encompasses a clinical spectrum from aborted sudden cardiac death due to ventricular arrhythmia (VA) usually in young affected patients to self-terminating ...

Activation recovery interval imaging of premature ventricular contraction. [PDF]
PLoS ONE, 2018 Dispersion of ventricular repolarization due to abnormal activation contributes to the susceptibility to cardiac arrhythmias. However, the global pattern of repolarization is difficult to assess clinically.

High heart rate associated early repolarization causes J‐waves in both zebra finch and mouse
Physiological Reports, 2021 High heart rates are a feature of small endothermic—or warm‐blooded—mammals and birds. In small mammals, the QT interval is short, and local ventricular recordings reveal early repolarization that coincides with the J‐wave on the ECG, a positive ...

Long QT syndrome provoked by induction of general anesthesia -A case report- [PDF]
Korean Journal of Anesthesiology, 2010 Long QT syndrome (LQTS) is an arrhythmogenic cardiovascular disorder resulting from mutations in cardiac ion channels. LQTS is characterized by prolonged ventricular repolarization and frequently manifests itself as QT interval prolongation on the ...

Case report: electrical storm during induced hypothermia in a patient with early repolarization
BMC Cardiovascular Disorders, 2017 Background Population based studies showed an association of early repolarization in the electrocardiogram (ECG) and a higher rate of sudden cardiac death presumably due to ventricular fibrillation.
