Abstract :

Aim: To compare blood pressure (SBP and DBP), heart rate, P wave duration, PR interval, QRS complex, QT interval, ST duration and T wave duration in young prehypertensive cases and normotensive controls. Materials and Methods: Total 600 subjects including 300 prehypertensive cases (20–45yrs age) and normotensive controls (20–45yrs age) were examined from Feuary 2019 to July 2020. The case and controls were taken from general population and medicine outpatient department of UPUMS, Saifai, Etawah. Detailed history and clinical examination was carried out and anthropometric measurements were recorded. Blood pressure of each subject was recorded by using manual sphygmomanometer in supine position. Electrocardiogram of each subject was recorded in supine position by using Clarity ECG: CMECG–01, Clarity Medical Private Limited. It is computer based automatic 12 lead ECG machine. Results: The mean difference between SBP and DBP, QRS duration, QT interval, ST changes, and T wave duration in prehypertensive cases and normotensive controls was found statistically significant, while the mean of heart rate, P wave duration, PR interval showing no statistical significance. Conclusion: The finding according to the present study suggested that most of the patient in the study, prehypertensive group had significantly higher BP, QRS interval, QT duration, ST changes, and T wave changes as compared to normotensive controls. The heart rate, p wave and PR interval had no significant comparative difference. Hence, the early evaluation of the prehypertensive individual with the help of electrocardiographic parameters may help to assess the cardiovascular status of an individual.
