Sildenafil citrate does not alter ventricular repolarization properties: novel evidence from dynamic QT analysis.


BACKGROUND Sildenafil citrate may have direct cardiac electrophysiological effects, and is possibly responsible for some cardiac events. The aim of our study was to investigate the effects of sildenafil citrate on QT dynamicity properties with a new QT analysis program showing even small changes in ventricular repolarization. METHODS Twenty-four-hour… (More)
