Key result
Single pass lead VDD pacing maintained reliable atrial sensing with the lowest P wave amplitude above 0.2 mV and achieved over 99% atrial synchronous ventricular pacing across different body positions.

Does a single-pass lead VDD pacing system maintain reliable atrial sensing and ventricular pacing across different body positions and physical activities in patients with high degree AV block?
Single-pass lead VDD pacing provides reliable atrial sensing and atrioventricular synchrony regardless of body position or physical activity in patients with high-degree AV block and intact sinus node function.
Kang et al. (1999) conducted an observational in High degree AV block and normal sinus node function (n=7). Single pass lead VDD pacing was evaluated on Percentage of atrial synchronous ventricular pacing. Single pass lead VDD pacing maintained reliable atrial sensing with the lowest P wave amplitude above 0.2 mV and achieved over 99% atrial synchronous ventricular pacing across different body positions.
