    Abstract:
    The hemodynamic effects of Propafenon were evaluated in 11 patients with acute myocardial infarction complicated by atrial and/or ventricular arrhythmias (atrial fibrillation in 4 cases, atrial premature beats in 3 cases, ventricular premature beats Class II-IVa in 4 and rapid sustained ventricular tachycardia in one case). Drug was administered as a bolus of 1-2 mg/kg in 5 min, followed by a 10-15 gamma/kg/min infusion for 24 hours in 7 patients. Serial measurements were taken of heart rate, systemic blood pressure, right atrial, pulmonary and capillary wedge pressure, cardiac output, cardiac index, total systemic resistances, left ventricular stroke work index, left ventricular ejection time and left ventricular mean ejection rate (LVMER) (8 cases) and PEP/LVET ratio (5 cases). After the intravenous bolus, a significant reduction of cardiac index (p less than 0.01) and LVMER (p less than 0.05) parallel to an increase of total systemic resistances and PEP/LVET ratio (p less than 0.01 and p less than 0.05 respectively); was observed no other parameter varied significantly. The peak hemodynamic effect was observed after 10 minutes and return to normal required from 30 minutes to 3-6 hours in the more severely affected patients. No late negative inotropic action was evident in 6 out of 7 patients who received long term infusion. Suppression or greater than 80% reduction of premature beats was evident in 9/12 cases. Sinus node function, atrioventricular and intraventricular conduction, and the QTc interval did not vary significantly.(ABSTRACT TRUNCATED AT 250 WORDS)
