Abstract:
AIM: To study the effect of changing left ventricular afterload and isolated perfused rabbit heart on ventricular refractory period measured by subhthreshold conditioning train stimulation (St).METHODS:Ventricu- lar refractory pened strength- interval relation was measured by St method under the condition of changine left ven- tricular afterload and elimination action of nervous and body fluid.RESULTS: Reducing left ventricular afterload pro -longed ventricular refractory period measured by St method (P
