Objective: To quantify the differences in the systolic and diastolic BP when three readings were taken (in sitting posture) at an interval of 5-10 minutes in hypertensive patients. Methodology: Twenty eight patients on anti-hypertensive therapy visiting the OPD were included in the study. Each person was seated in a quiet room for 5 minutes, followed by the recording of the blood pressure. The blood pressure was recorded two more times at an interval of 5 minutes between each recording. After 3 sitting recordings, a 4th reading was obtained in standing posture. Results: Results were analysed based on the JNC VII guidelines according to which a difference of more than 10 mm of Hg of systolic blood pressure and more than 5 mm of Hg differentiates various grades of hypertension. First reading was compared with the second and the third reading successively and analysed. 32.14% of the patients showed aberrant readings. 14% of the subjects, each, showed a significant difference between the first and the second reading and the first and the third systolic readings. Around 46% and 75% of the patients showed a significant difference in SBP and DBP respectively when compared between sitting and standing postures. Conclusion: It would be ideal to record blood pressure at least twice before labeling a patient as hypertensive, and also before adjusting the dose of the drugs in a hypertensive.
