The acute hemodynamic effects of right ventricular septal pacing in patients with congestive heart failure secondary to ischemic or idiopathic dilated cardiomyopathy.
To assess the hemodynamic effects of right ventricular septal pacing in patients with severe chronic heart failure, we studied 13 patients during intrinsic rhythm and with pacing in the VDD mode at atrioventricular delays of 100 to 200 ms. There was no improvement of any hemodynamic parameter measured with pacing, even in the subgroup of patients with prolonged PR intervals.
