PR interval is the important ECG parameter dependent on the heart and it indicates time required for conduction from atria to the ventricle. Physiological parameters show variations in normal subjects. The Physiological parameters also show gender variations. This study was conducted to compare the PR interval in males and females of same age groups.
To study and compare PR interval in males and females of same age group
Males and females of age from 20 years to 80 years were studied. ECG in lead II was recorded using Power lab 8/30 series
Mean standard deviation and proportion was used to present the data. Student‘t’ test was done. Pearson's correlation coefficient ‘r’ was used to examine relationship between ECG changes with difference age groups. A two tailed p-value less than 0.05 will be considered as significant.
PR interval increases as age increases. Prolongation of PR interval in females compared to males of same age group
PR interval may be prolonged even in clinically healthy individuals. As PR interval is determining conduction from atria to ventricles, individual with prolonged PR interval must have regular follow up for early detection of cardiovascular problem as degenerative changes are occurring with increasing age.
