The pathological changes are evident in brain during stroke especially due to ischemic causes. There are significant changes seen in EEG and MRI among stroke cases along with ECG changes in the heart irrespective of pre-existing cardiac diseases. The objective of this study was to assess the frequency and relationship of ECG and EEG changes associated with acute stroke patients. A hospital based and cross-sectional study was carried out among the acute stroke patients attending the emergency care facility in Medical college Hospital in Bangalore during 2013-2014.Detailed history including the high-risk factors, attributing risk behaviour or habits and their clinical profile was prepared with complete clinical examinations of all the patients, EEG, MRI and ECG were done within 24 hour of hospitalisation with necessary blood tests at individual level. There were 125 and 55 male and female patients were eligible for analysis. The ECG abnormalities were observed in 60% and it was 63% and 52% in male and female cases. The EEG abnormal waves reported in males (8.8%) than females (14.5%). ACA, MCA and PCA affected in 19.3%, 52.3% and 28.4% cases respectively. ECG abnormalities predominantly LVH and Ischemia was seen in the age group of 56 years and above. EEG abnormalities were seen more in males than females. To conclude, stroke patients will have ECG and EEG abnormalities in acute ischemic stroke and can be correlating with infarct volume at local site. Further studies are needed to define brain heart interaction in high risk cases.
