Abstract:The immediate haemodynamic and electrophysiologic effects of intravenous prenalterol 2.5–75μg/kg in patients with coronary heart disease without clinical heart failure were investigated during fixed rate atrial pacing. Right ventricular peak dP/dt increased pronounced and serum concentration dependent after prenalterol concomitant with an increase in stroke volume and a moderate decrease in peripheral vascular resistance. The effects on haemodynamics after prenalterol were thus serum concentration dependent bu… Show more
