Key result
Hypertension in Indian adults was associated with reduced heart rate variability total power compared to normotensive individuals.
Why the study?
Autonomic imbalance is observed in hypertensive individuals, motivating a comparison of heart rate variability between normotensive and hypertensive Indian adults.
Is heart rate variability reduced in hypertensive compared to normotensive Indian adults?
Observational
Is heart rate variability reduced in hypertensive compared to normotensive Indian adults?

Hypertension is associated with a significant reduction in heart rate variability, indicating autonomic imbalance in this population.
Autonomic imbalance is seen in hypertensive. This study was designed to compare heart rate variability in normotensive and hypertensive Indian adults. HRV records beat to beat variation in R-R intervals in milliseconds in electrocardiogram. Lead II ECG was recorded and a 5 minutes' stationary, artifacts free recording was selected for data analysis. HRV measures like total power was significantly less in hypertensive (303.37 ± 438.1) as compared to normotensive (534.16 ± 818.41). Standard deviation of normal-to-normal RR intervals was significantly reduced in hypertensive. A significant reduction of HRV was seen in hypertensive as compared to normotensive.
