Recurrent syncope of unknown origin: value of permanent pacemaker insertion
International Journal of Cardiology
|August 1, 1995
Summary
Permanent pacemaker insertion may benefit patients experiencing recurrent Stokes-Adams attacks without clear electrocardiographic evidence of bradyarrhythmia. This intervention led to symptom resolution or improvement in most patients studied.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Stokes-Adams attacks can present without overt electrocardiographic findings of bradyarrhythmia.
- The efficacy of permanent pacing in such cases remains under-explored.
Purpose of the Study:
- To evaluate the outcomes of permanent pacemaker implantation in patients with a history suggestive of Stokes-Adams attacks but lacking electrocardiographic evidence of bradyarrhythmia.
Main Methods:
- A cohort of 11 patients meeting specific inclusion criteria underwent permanent pacing.
- Follow-up was conducted over a mean period of 5.4 years to assess symptom recurrence and improvement.
Main Results:
- Seven out of eleven patients became symptom-free after pacemaker implantation.
- Two additional patients experienced significant symptom improvement.
Conclusions:
- Permanent pacemaker insertion appears to be a viable treatment option for carefully selected patients with recurrent Stokes-Adams attacks and normal baseline electrocardiograms.
- This approach may offer substantial symptomatic relief in challenging cases.
