22 patients with syncope and significant aortic stenosis underwent electrophysiological evaluation in addition to the hemodynamic study. Abnormalities of impulse formation or conduction were present in 12 patients. 6 patients demonstrated HV times ≥ 55 msec. There was no correlation between the aortic valve gradient and the HV interval, between the enddiastolic volume of the ventricle and the HV time and between aortic valve calcification and the HV time. Syncopal attacks were corrected with aortic valve replacement even in patients with prolonged HV times.
