Abstract:
AIM:To study the effects of changing right heart load on electrophysiologic parameters in anesthetized dogs. METHODS:Change of right atrial and ventricular load, right atrial and ventricular diastolic threshold (ADT, VDT), right atrial and ventricular relative refractory period (ARRP,VRRP) and right atrial and ventricular effective refractory period (AERP, VERP) were recorded. RESULTS: Increasing right heart load step by step(grade A and B) caused prolongation of ARRP, AERP, VRRP (grade B, P
