Summary
Syncope in patients with sick sinus syndrome after cardiac pacing is often caused by autonomic issues or pacemaker problems. Pre-implant factors like male gender and younger age predict syncope risk.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Context:
- Sick sinus syndrome necessitates permanent cardiac pacing for symptom management.
- Despite effective pacemaker function, syncope can persist, with unknown causes.
- Understanding syncope predictors and etiologies in paced patients is crucial.
Purpose:
- To identify predictors and causes of syncope in patients with sick sinus syndrome who have undergone permanent cardiac pacing.
- To review clinical experience with syncope in this patient population.
Summary:
- A study of 153 patients with sick sinus syndrome and pacemakers found a 10-year syncope incidence of 13%.
- Common causes included autonomic insufficiency (45%), pacemaker/lead malfunction (30%), and pacemaker syndrome (10%).
- Pre-implant predictors for syncope were male gender and age under 70.
Impact:
- Identifies key etiologies of syncope in paced sick sinus syndrome patients, including autonomic dysfunction and pacemaker issues.
- Suggests pre-implant evaluation for neurogenic syncope may reduce recurrent episodes.
- Highlights the need for comprehensive troubleshooting of pacemaker function and autonomic status.
