Key result
In 100 patients with acute stroke, ECG abnormalities were common, and mortality was higher in patients with abnormal ECGs following an acute cerebrovascular event.
Why the study?
Electrocardiographic abnormalities occur in neurological disease, but their specific frequency, manifestations, and relation to mortality across different types of stroke required further study.
Observational (n=100)
No
ECG abnormalities are common in acute stroke, and specific changes such as ST-T abnormalities or U waves are associated with higher mortality, highlighting their prognostic value.
ECG changes in stroke may warrant cardiac evaluation; Level 4 data leaves open prognostic or therapeutic implications.
Cerebrovascular accident plays an important role in the morbidity and mortality of adults posing serious medical, socio-economic and rehabilitation problems. Electrocardiographic abnormalities have been known to occur in the context of neurological disease. The current study is an observational study aimed at elucidating the relation between cerebrovascular accident and ECG. To determine the frequency of ECG changes in cerebrovascular accident and to determine the variations in ECG manifestations and mortality in different types of stroke. 100 patients of acute stroke were considered. ECG was recorded in these patients within 24 hours of admission. Follow up of admitted patients was done to know the prognosis. ECG abnormalities noted among cerebral ischemic patients were presence of T Wave inversion (34.48%) and ST segment depression (32.76%) followed by QTc Prolongation (29.31%) and presence of U waves (27.59%). In cases of haemorrhagic Stroke, T wave inversion (33.33%) and arrhythmias (33.33%) were followed by U waves (30.95%) and ST segment depression (23.81%). Mortality was higher in patients with ST-T changes in ischemic group (66.66%) and in patients with positive U waves (60%) in haemorrhagic group. Studying ECG changes will provide insight in prognosis and management of stroke patients and may alter their management in coming future. ECG changes occurred very commonly in acute stroke. The changes are thought to be independent of the nature of stroke. It was noted that ST and T inversion being common in ischemic while T inversions and arrhythmias common in haemorrhagic CVA. It was also noted that the mortality was higher in patients with abnormal ECG following an acute Cerebrovascular event.

Sebastian et al. (2021) conducted an observational in Acute cerebrovascular accident (n=100). Acute cerebrovascular accident was evaluated on Frequency of ECG changes and mortality in different types of stroke. In 100 patients with acute stroke, ECG abnormalities were common, and mortality was higher in patients with abnormal ECGs following an acute cerebrovascular event.
