Results
Overall, local ventricular thresholds were elevated during follow-up. The distal and proximal HBP thresholds did not differ. The local ventricular thresholds of distal HBP were significantly lower than those of proximal HBP. Optimal values of the ventricular measurements at implantation were determined for predicting the accepted ventricular threshold at 6 months. Distal HBP supported by stable local ventricular capture may be useful for treating pacing-dependent patients.

Fifty patients with bradycardia (58% with atrioventricular block) underwent successful HBP and were followed
for 1 year. Precise locations of the lead tips were confirmed using follow-up echocardiography.
