Background: Incidence of stroke is rising in India with great impact on morbidity and mortality. One of the most important predictor linked with poor outcome among stroke patients is electrocardiographic (ECG) changes resulting from massive autonomic discharge that interferes with cardiac autonomic control. Aims and Objectives: To study and compare ECG changes in ischemic and hemorrhagic stroke and correlate with patient’s outcome. Materials and methods: One hundred and four stroke patients were studied in Department of Neurology, GR Medical College and JA Group of Hospitals, Gwalior from May 2015 to August 2016. Patients were diagnosed as stroke by WHO classification and confirmed by brain imaging as CT scan or MRI. Stroke patients were assessed for the severity of stroke as per the ICH and GCS score followed by brain imaging and various lab parameters assessment. Results: Ischemic stroke (58.65%) was more prevalent compared to hemorrhagic (41.34%). Stroke was more common in male population (65.38%)]. Among risk factors in ischemic and hemorrhagic group smoking (21 vs. 21 respectively), hypertension (32 vs 33 respectively) and diabetes (17 vs 8 respectively) were common risk factors. Mortality was high among the hemorrhagic group (n=20) compared to ischemic group (n=6). Eleven ECG patterns were identified out of which ST segment elevation, ST segment depression; tall T wave, T wave depression and presence of U wave were dominant. These parameters were significantly seen in patients who expired in hemorrhagic group whereas in ischemic group distribution of patients who were alive and expired was comparable. Conclusion: Different ECG changes are observed in stroke patients even in absence of primary cardiac disease and these ECG changes can be predictor of prognosis.
