Key result
A single-pass lead VDD pacing system achieved an atrial synchronization ratio of ≥98% in at least 95% of patients with symptomatic AV conduction disturbances over a mean follow-up of 385 days.

Does a single-pass lead VDD pacing system provide reliable atrial synchronization in patients with symptomatic AV conduction disturbances and competent sinus node?
A single-pass lead VDD pacing system provides highly reliable atrial synchronization in patients with AV block and normal sinus node function.
G Curzio (1991) conducted an observational in Symptomatic AV conduction disturbances and competent sinus node (n=237). Single-pass lead VDD pacing system was evaluated on Percentage of atrial synchronization (ratio between atrial triggered ventricular paced complexes and all ventricular paced complexes). A single-pass lead VDD pacing system achieved an atrial synchronization ratio of ≥98% in at least 95% of patients with symptomatic AV conduction disturbances over a mean follow-up of 385 days.
