Abstract

Background: Determination of the electrocardiographic changes among the hypertensive patients can reveal the early cardiac abnormalities. Objectives: The purpose of the present study was to find out the common electrocardiographic (ECG) changes in different grades of hypertensive patients.

Data were collected by face to face interview with a pre-designed structured questionnaire. Measurement of the blood pressure and the 12-lead surface electrocardiogram were done among the study group in a resting state. Results: A total number of 400 mild to severe grade hypertensive patients were recruited for this study of which male was 300 cases and female were 100 cases. The age ranges was 30 to 60 years, Among 400 hypertensive patients, abnormal electrocardiographic changes were found in 212(53%) patients.
