A patient with moderate aortic stenosis, left ventricular hypertrophy, and a permanent right ventricular pacemaker for a sick sinus node presented with hypotension, dizziness, and angina pectoris with paced beats. The hemodynamics of pacing were documented with non-invasive and invasive studies. The patient was successfully treated with a programmable generator and pacing at a lower rate. The neccessity of evaluating the effects of a temporary pacemaker before insertion of a permanent one and of a reevaluation of the hemodynamic status in the presence of unexplained cardiac failure in a patient with permanent pacemaker are emphasized in this case report.
