Abstract

PR interval is the interval between the onset of P wave and the onset of QRS complex. The normal PR interval is in the range of 0.12–0.28 sec Prolonged PR interval may be due to delayed conduction from atria to ventricles. Sometimes prolonged PR interval is seen in clinically healthy patients. In females till menopause the blood pressure is less than males of same age group due to protection by oestrogen. Aftermenopause risk of hypertension and also heart diseases increases. Again increasing age itself is responsible for degenerative changes in body. So this study was done for variation in PR interval in females with increasing age.

To study PR interval variations in females of different age groups.

Females of different age from 20 years to 80 years were studied. ECG in lead II was recorded using Power lab 8/30 series. Mean standard deviation & proportion was used to present the data. Students‘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.

Prolongation of PR interval with increasing age

Although clinically healthy, females with prolonged PR interval must be advised regular follow up to detect early cardiac insufficiency.
