Key result
Among 1,126 individuals, inter-arm systolic blood pressure variation was 0-10 mmHg in 936 subjects, 11-20 mmHg in 178 subjects, and 21-30 mmHg in 12 subjects.
Why the study?
Blood pressure should be measured in both arms because differences exist and single-arm measurement may cause hypertension underdiagnosis, while confirming inter-arm differences requires repeated measurement to avoid overestimating prevalence.
What is the prevalence of inter-arm blood pressure and pulse rate variation, and is it associated with cardiovascular disease?

Measuring blood pressure in both arms is important as inter-arm variations of 21-30 mmHg may indicate underlying cardiovascular disease.
Background: Blood pressure is vital sign, along with heart rate, oxygen saturation, respiratory rate and body temperature. Blood pressure, in normal adult, is approximately 120/80 mmHg. Difference between measured systolic and diastolic pressures is called pulse pressure. Pulse pressure is due to cardiac output. Blood pressure should be measured in both arms at first visit because differences exist and measurement in only one arm may lead to under diagnosis of hypertension. Confirmation of an inter-arm difference requires a method of repeated simultaneous measurement, to avoid overestimation of prevalence. Method: Apparatus used is digital sphygmomanometer. Blood pressure and pulse rate is measured of both arms, thrice each time, concordant readings are considered and noted for this purpose of blood pressure and pulse rate in different age groups persons. Result: Total Persons investigated of different age groups = 1126, Males = 517, Females = 609, total SBPV in range of 0-10mmHg =936, 11-20mmHg=178, 21-30mmHg=12. DBPV in range of 0-10mmHg=1097,11- 20mmHg= 26, 21-30mmHg=3.PV=26, 0-10mmHg=1109,11-20mmHg=15, 21-30mmHg=2. Diseased persons=325, Normal persons=801. Conclusion: Variation in blood pressure and pulse rate in inter-arms observed in different age groups from 0-10mmHg to 21-30mmHg. More variation may show cardiovascular disease in individual. Total person investigated are 1126 out of which 801 are normal and 325 are suffering with hypertension, diabetes, hypertension with diabetes and hypotension. Maximum variation is found in 0-10mmHg in systolic blood pressure, diastolic blood pressure and pulse which is not showing significant diseases and minimum in 21- 30mmHg which is showing cardiovascular diseases and their probabilities.

Naresh Vashist (2020) conducted a cross-sectional in Inter-arm blood pressure variation (n=1,126). Inter-arm blood pressure measurement was evaluated on Inter-arm variation in systolic blood pressure. Among 1,126 individuals, inter-arm systolic blood pressure variation was 0-10 mmHg in 936 subjects, 11-20 mmHg in 178 subjects, and 21-30 mmHg in 12 subjects.
