Retrospective analysis of mode survival, reliability of atrial sensing and incidence of atrial tachyarrhythmias in 307 single-lead VDD pacemaker patients
Key result
Single-lead VDD pacemakers in patients with isolated atrioventricular block were associated with a 65% incidence of atrial tachyarrhythmias over a 10-year period.
Why the study?
Does single-lead VDD pacemaker implantation maintain VDD mode survival and atrial sensing in patients with isolated atrioventricular block?

Overview
High atrial tachyarrhythmia rates may warrant enhanced monitoring with VDD pacemakers; leaves open questions on long-term mode survival in isolated AV block.

Population
307 patients with isolated atrioventricular block who received single-lead VDD pacemakers, followed over a 10-year period.
E
Exposure
Single-lead VDD pacemakers
O
Outcome
VDD mode survival, development of atrial tachyarrhythmias (AT), and long-term atrial sensing performance
While single-lead VDD pacemakers can be applied without serious complications, they are associated with a high long-term incidence of atrial tachyarrhythmias (65%) in patients with isolated AV block.
Cite This Study
Zupan et al. (2006) conducted an observational in isolated atrioventricular block (n=307). Single-lead VDD pacemakers was evaluated on development of atrial tachyarrhythmias (AT). Single-lead VDD pacemakers in patients with isolated atrioventricular block were associated with a 65% incidence of atrial tachyarrhythmias over a 10-year period.
