In ten patients undergoing catheter ablation of the atrioventricular junction (CAVJ) because of therapy refractoriness of supraventricular arrhythmias, the effect of repeated high energy direct current (DC) shock on left ventricular function has been investigated. End-systolic pressure-volume relation (ESPVR) and the positive first derivative of ventricular pressure (dP/dt) have been used as indices of left ventricular systolic function, while the time constant of isovolumic pressure decay, the diastolic stiffness, and the negative dP/dt represented the diastolic function parameters, respectively. Each patient received at least two and no more than three DC shocks for successful CAVJ, with an energy of 360 joules. Significant acute reduction of both systolic and diastolic function was noted after each DC shock, with a slow partial recovery of both phases. The recovery process involved the systolic phase earlier and more completely than the diastolic one. The alterations observed could not be predicted from preablation values, but were significantly related to cumulative energy dose index for body weight. In conclusion, repeated high energy DC shocks acutely, but reversibly, impair left ventricular function; in addition, the ventricular function reduction is primarily related to the total ablation energy indexed for body weight.
