VARIATION IN HEART RATE AMONG HEALTHY INDIVIDUALS

Variability of heart rate is considered as an indicator of autonomic status. Very little work has been done on heart rate variability in normal healthy volunteers. Objective: Our aim was to increase the reference values of heart rate variability in our healthy population. Study Design: A non- interventional descriptive study. Place and Duration: In the Physiology Department of Services Hospital Lahore for one year duration from March 2016 to March 2017. Method: Holter monitoring was performed between 'Reynolds Medical' and 'Holter ECG Recorder' using CF Card life for healthy volunteers from 37 to 24 hours. Results: The average rhythm of heart rhythm in normal healthy volunteers in our population, RR intervals standard deviation (SDNN), NN intervals (SDANN) and NN intervals with sequential Root standard deviation square root. (RMSSD) were evaluated. A change in heart rate variability between foreign volunteers, RMSSD and domestic people was significant high in the local population (p
