Abstract

Purpose: In this study, we wanted to correlate the change in the blood pressure in supine position on immediately standing up to the change in blood pressure after 2 minutes of standing in hypertensive and normotensive individuals. Materials and Method: By keeping inclusion and exclusion criteria, the 50 subjects selected for this study were aged between 15 and 55 years, were of both sexes and were categorized into four groups based on their age. By taking the position of the patient into consideration, blood pressure was recorded in the lying and the standing posture. Error difference in blood pressure was found in standing position by double recording. Questionnaires evaluated about smoking habits, medication use and history of past illness. Statistical analysis was done by t-test. Result: From the above study, it is found that blood pressure in hypertensive patients varies in lying position than in standing position (p < 0.01) with less error in blood pressure recording (p < 0.05). It also shows that in hypertensive persons, systolic blood pressure increases compared to diastolic blood in standing position as well as sitting position. Conclusion: Thus it was concluded that there is significant correlation between blood pressure and posture which varies in lying position than in standing position in hypertensive patients.
