Manish Ranjan, Anil Kumar Singh

Abstract :

Background and Aim: A study was conducted to determine the effect of exercise on Electrocardiogram (ECG) variables in First year students of NMC,Patna , and gender variation of these variables was compared. Materials and Methods: 100 medical students were considered (55 males and 45 females), ages 18–24 years. The volunteers were subjected to exercise stress test by using bicycle ergometer. They exercised till exhaustion or attainment of 85% Heart Rate Maximum (HRmax) (Modified McArdle Protocol). ECGwas recorded pre and post–exercise. Results: The weight ranges from 45.37 ± 6.53 kg. QRS duration ranged from 0.04 to 0.12 seconds mean of 0.064 seconds. QRS voltage in V6 varied from 0.30 to 2.1 mv with a mean of 1.14 mv. The QTc interval was 0.31 to 0.47 seconds mean was 0.39 seconds. Conclusion: The study revealed an unexpected finding where PR, QRS and QT durations were prolonged post–exercise in apparently healthy young medical students.
