ventricular extrasystoles การใช้

• Ventricular escape beats differ from ventricular extrasystoles ( or premature ventricular contractions ), which are spontaneous electrical discharges of the ventricles.
• Studies ( notably the Cardiac Arrhythmia Suppression Trial ) have shown an increased mortality when flecainide is used to suppress ventricular extrasystoles in the setting of acute myocardial infarction.
