Stroke and atrial fibrillation in sick sinus syndrome.

Stroke and atrial fibrillation in sick sinus syndrome.

Chronic atrial fibrillation and stroke in paced patients with sick sinus syndrome. Relevance of clinical characteristics and pacing modalities.

BACKGROUND The goal of the report was to study the long-term incidence and the independent predictors for chronic atrial fibrillation and stroke in 507 paced patients with sick sinus syndrome, adjusting for differences in baseline clinical variables with multivariate analysis. METHODS AND RESULTS From 1980 to 1989, we implanted 376 dual-chamber, 19 atrial, and 112 ventricular pacemakers to tr...

Coexistence of sick sinus rhythm and atrial flutter-fibrillation.

A 58-year-old man with hypertensive cardiovascular disease and atrial flutter underwent electrophysiologic studies, including multiple intra-atrial recordings and atrial stimulation. Although the surface ECG suggested the presence of atrial flutter, intra-atrial recordings demonstrated the presence of (1) sinus-like rhythm localized to an area of approximately 5 mm in and around the region of t...

Ischemic stroke after cardiac pacemaker implantation in sick sinus syndrome.

The risk of embolic stroke during sick sinus syndrome before cardiac pacemaker insertion is substantial, but stroke after pacemaker insertion has not been well studied. We observed 10 sick sinus syndrome patients who developed an ischemic stroke 4 days to 112 months after pacemaker insertion. Nine patients represented 6% of the 156 ischemic stroke patients observed during a 30-month period. Eig...

Atrial size independently correlates with the development of paroxysmal atrial fibrillation in patients with sick sinus syndrome.

BACKGROUND Atrial fibrillation arises in 20-30% of patients with sick sinus syndrome, increasing the risk of systemic embolization and mortality. The aim of this study was to examine the clinical determinants of development of paroxysmal atrial fibrillation in sick sinus syndrome patients before implantation of a pacemaker. METHODS This case-control survey involved 144 patients (mean age ± SD...
