Probucol administration of 4 weeks produced torsades de pointes associated with exacerbated QT interval prolongation in a 36-year-old woman with Romano-Ward syndrome. With discontinuance of probucol, the QT interval corrected for rate shortened from 620 msec to 500 msec and ventricular ectopic beats disappeared completely. Although probucol is known to prolong the QT interval, associated ventri...
BACKGROUND The increase in inward current, primarily L-type Ca2+ current, facilitates torsades de pointes (TdP). Because human atrial natriuretic peptide (ANP) moderates the L-type Ca2+ current, in our study it was hypothesized that ANP counteracts TdP. METHODS AND RESULTS We tested the effect of ANP, guanosine 3', 5'-cyclic monophosphate analogue (8-bromo cGMP) and hydralazine on the occurre...
Cardiovascular manifestations of COVID-19 include cardiac rhythm disturbances, whose mechanisms, incidence, and most common types are not well established in this population. Intense inflammatory response metabolic activity contribute to recurrence pre-existing arrhythmias, other arrhythmias can occur due myocardial injury, acute coronary insufficiency, electrolyte disturbances. Brady- tachyarr...
Background: The long QT syndrome is characterized by prolongation of interval, which may lead to life-threatening cardiac arrhythmias. Objectives were assess prevalence, quantity and severity QTc with combined drugs (azithromycin hydroxychloroquine) in adults COVID-19 patients treated on these agents at KFSHRC. And characterize complications drugs.Methods: A retrospective cohort study KFSH&...
