DOI: 10.1016/j.jelectrocard.2021.08.020
Abstract: BACKGROUND Because of cardiac hypertrophy and electrophysiological alterations associated with preeclampsia, worsening of preexisting arrhythmias or occurrence of de novo arrhythmias are common in patients with preeclampsia. Tp-e/QT and Tpe/QTc ratios are accepted as reliable… read more here.

DOI: 10.1093/sleep/zsad077.0441
Abstract: Obstructive sleep apnea (OSA) is associated with prolonged ventricular repolarization at baseline that further increases during sleep when an apnea/hypopnea event occurs. Aggressive treatment of OSA with positive airway pressure therapy (PAP) may further prolong… read more here.

DOI: 10.1111/anec.12713
Abstract: The duration of ventricular repolarization (VR) and its spatial and temporal heterogeneity are central elements in arrhythmogenesis. We studied the adaptation of VR duration and dispersion and their relationship in healthy human subjects during atrial… read more here.
