CLINICAL STUDY OF ELECTROCARDIOGRAM CHANGES IN DIFFERENT TYPES OF CEREBROVASCULAR ACCIDENTS AND PROGNOSTIC SIGNIFICANCE
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 49
Abstract
BACKGROUND AND OBJECTIVES Stroke is one of the most common causes of death worldwide. People who suffer cerebrovascular accidents also have an abnormality in the hearts electrical cycle are at a higher risk of death with 90 days than people who do not have abnormal electrical activity. The ECG changes have been reported predominately with subarachnoid haemorrhage and intracerebral haemorrhage and in a few percentage of cases of cerebral infarct. Present study is an attempt to study the pattern ECG abnormalities in patients with cerebrovascular accidents and its prognostic significance. METHODOLOGY Prospective study of 100 patients admitted to the casualty or outpatient department of B. R. Ambedkar Medical Hospital, K. G. Halli, Bangalore, with diagnosis of first episode of cerebrovascular accident were taken up for the study. RESULT Among 100 patients, 59 were males and 41 were females. The incidence of stroke increases with age 22% between 60 and 65 days to 40% above 70 years. Cerebral thrombosis was the most common cerebrovascular accident seen in 53 patients and subarachnoid haemorrhage least common seen in six patients. The ECG changes were seen in 82 patients. The ECG changes were QTC prolongation (30%), ST segment changes (28%). T-wave changes (44%), U-wave changes (10%), LVH (36%), sinus bradycardia (10%), sinus tachycardia (24%). These abnormalities were commonly seen in cerebral haemorrhage and subarachnoid haemorrhage than the infarct. The overall immediate mortality was 22% and did not relate to the ECG changes seen, but was dependent on level of consciousness, type of CVA, extent of lesion and other co-existent disease. CONCLUSION Patient with cerebrovascular accident often have abnormal ECG changes in absence of unknown organic heart disease or electrolyte imbalance, more common in intracerebral haemorrhage and subarachnoid haemorrhage. The most common ECG changes are T-wave changes, prolonged QTC, ST segment changes and arrhythmias. The ECG changes did not relate to the mortality in patients with cerebrovascular accidents.
