Implication

Pacing may relieve symptoms in sinoatrial syndrome; leaves open need for randomized confirmation before practice change.

Key Points

To evaluate the clinical features, associated cardiac conditions, and symptom response following permanent cardiac pacemaker implantation in patients with sinoatrial syndrome.
Analyzed N=90 patients with sinoatrial syndrome identified from a cohort of 392 pacemaker recipients (mean age 66 for men, 70 for women; male-to-female ratio 1:1.6).
Monitored clinical outcomes and symptom resolution over a follow-up period ranging from 3 months to 7 years (mean 23 months) following pacemaker implantation.
Permanent pacing stopped syncopal attacks in 48 of 49 patients (98.0%) and completely relieved dizziness in all 28 affected patients (100%).
Tachyarrhythmias were effectively controlled in 43 of 51 patients (84.3%) through combined cardiac pacing and antiarrhythmic drug treatment.
Nineteen deaths occurred during follow-up, primarily from cerebrovascular events or myocardial infarction, with zero mortality associated with implantation or replacement procedures.

Structured PICO

Does permanent cardiac pacing improve symptoms in patients with sinoatrial syndrome?

Population

90 patients with sinoatrial syndrome (out of a pacemaker population of 392 patients), ages 22 to 86 years, mean age 66 for men and 70 for women, male-to-female ratio 1:1.6.

Intervention

Permanent cardiac pacing (pacemaker implantation)

Outcome

Control of symptoms (syncopal attacks, dizziness, and tachyarrhythmias)

Permanent cardiac pacing effectively controls symptoms of syncope and dizziness in patients with sinoatrial syndrome, particularly when drug treatment fails.
