Introduction: The change in parasympathetic function is generally known physiological changes in aging of man. The present study was intended to evaluate Postural tachycardial index with age. Aim: To measure basal parasympathetic activity by using Postural tachycardial index in younger and elderly and to observe effect of aging on it. Materials and Methods: The subjects selected are 120 in number with age group 35 to >65 years of both sex and they are categorized into 4 groups based on their age. Group- I: The age of 35-45 years; Group-II: The age of 45- 55 years; Group-III: The age of 55-65 Years; Group-IV: The age of >65 years. PTI was measured by using ECG machine. Results: The examination of parameters body mass index, Heart Rate during resting, immediate standing were estimated for all subjects. The data was analyzed by using descriptive and inferential statistics. Discussion: The findings suggested that the mean of PTI decreases statistically in group III and IV. Conclusion: This study concluded that due to autonomic dysfunction the PTI decreases with increase in age. KEY WORDS: Postural tachycardial index, Body mass index, heart rate, Autonomic dysfunction.
