BACKGROUND AND OBJECTIVES: With advancing age, degenerative changes occur in heart muscle and its conduction system. This study was undertaken to see the ECG changes in different age groups of healthy adults.
MATERIALS & METHODS: A cross sectional study was conducted in a group consisting of 150 (75 male and 75 female) Healthy adults in the age group 21 to 80 years. All the subjects were divided into different subgroups according to their sex and age. Lead II ECG was recorded on all subjects in supine position in an ambient temperature for 3 minutes by using Power lab. And the analysis of the ECG was done by the software in the same instrument. RR interval, Heart rate and ST height were used for analysis.
RESULTS: There was prolongation of R-R interval and decrease in heart rate and ST height with increasing age in both males and females.
CONCLUSION: In this study we saw changes in different ECG parameters in both males and females of different age groups. There were changes in some of the ECG parameters between males and females of different age groups. But all these changes were within physiological limits.
