The pacemaker syndrome: Old and new causes
Key result
Pacemaker syndrome occurs mostly with VVI pacing but is often managed by adjusting the generator.
Why the study?
The pacemaker syndrome arises from inadequate timing of atrial and ventricular contractions causing symptoms in pacemaker patients, with new causes beyond VVI pacing recognized.

Implication
Alerts clinicians to pacemaker syndrome risk across modes; leaves open optimal programming strategies in dual-chamber devices.

Population
Patients with pacemakers
E
Exposure
Pacemaker systems (VVI, atrial, and dual-chamber pacing)
O
Outcome
Pacemaker syndrome (symptoms and signs caused by inadequate timing of atrial and ventricular contractions)
Pacemaker syndrome is primarily caused by loss of atrioventricular synchrony in VVI pacing but can also occur in other modes, highlighting the importance of restoring normal AV contraction sequences.
Cite This Study
Schüller et al. (1991) conducted a review in Pacemaker syndrome. Pacemaker systems was evaluated. Pacemaker syndrome, caused by atrioventricular asynchrony, occurs mostly with VVI pacemakers but can also be seen in atrial and dual-chamber pacing, and can often be managed by adjusting the generator.
