  • Abstract
  • Look Inside

The hemodynamic and electrophysiological effects of the intravenous administration (3.0 mg/ kg) of mexiletine were studied in twelve patients. Cardiac output was significantly reduced from a mean control value of 5.9±2.0 to 5.1±1.4 1/min (p<0.01). Total pulmonary resistance were signifi-cantly increased by 11%. Mexiletine had no consistant effect on heart rate, systemic arterial blood pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure and systemic vascular resistance.

Significantly AH interval was increased by 8%, and maximum sinus node recovery time was reduced by 16%. The effective and functional refractory periods of the AV node and His-Purkinje system were significantly reduced. No significant changes ocurred in HV interval, sinoatrial conduction time, AV conduction and refractory period of atrium.

Mexiletine had negative inotropic effects, however, no adverse effects on sinus node function, AV conduction and His-Purkinje system.
