FREQUENCY OF INTER-ATRIAL BLOCKS IN PATIENTS WITH ISCHEMIC STROKE
Objective: To determine the frequency and association of Interatrial block in hospitalized patients with Ischemic Stroke.
Study Design: A case control study.
Place and Duration of Study: Department of medicine, Military Hospital, Rawalpindi from 1st Jan 2009 to 30 December 2009.
Methodology: It included 64 patients, 32 cases of diagnosed ischemic stroke and 32 patients were taken as controls not suffering from ischemic stroke or ischemic heart disease. ECG findings of both selected groups were evaluated for presence or absence of interatrial block.
Results: Out of 32 ischemic stroke patients, 14 (43.85%) were found to have interatrial block on electrocardiogram (ECG). Whereas only 6 (18.80%) controls were found to have interatrial block on ECG. Odds ratio was 1.66.
Conclusion: Interatrial block is more frequent in ischemic stroke patients and may represent a risk factor for such stroke.
