Objective: To determine the frequency and association of Interatrial block in hospitalized patients with Ischemic Stroke.
Results: Out of 32 ischemic stroke patients, 14 (43.85%) were found to have interatrial block on electrocardiogram (ECG).
Conclusion: Interatrial block is more frequent in ischemic stroke patients and may represent a risk factor for such stroke.
ECG findings of ischemic stroke patients were evaluated for presence or absence of interatrial block. Interatrial block was defined as prolonged p wave ([greater than or equal to] 110 ms) on electrocardiogram.
Chi square test was applied to compare the frequency of interatrial block in cases and controls and odds ratio was calculated, p value less than 0.05 (p0.05) and gender (p>0.05).
