The syndrome of sinus bradycardia with variable heart rate may result in Stokes-Adams episodes. Ventricular pacing is the usual method of treatment for cardiac syncope, but atrial pacing is hemodynamically superior if adequate AV conduction is intact. This study reports the hemodynamic status of patients with sinus bradycardia and analyzes the consequences of right ventricular endocardial pacing.
Thirteen patients (nine male, four female, average age, 72) were studied. The AV conduction as determined by His bundle recording was found to be normal in nine and abnormal in three patients. At the average control heart rate of 49/min, the average cardiac
