ABSTRACT
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.
