ASSESSMENT OF CARDIAC AUTONOMIC DERANGEMENT IN SMOKERS BY COUNTING RESTING HEART RATE AND COUNTING HEART RATE AFTER INDUCING STRESS

Abstract

Introduction There is an established link between Heart Rate (HR) and cardiovascular health. HR is a very important vital parameter and it is an index of myocardial activity. According to the previous studies, smokers resting HR will be more due to autonomic dysfunction. The body releases a surge of hormones when under stress. These hormones cause the heart to beat faster and the blood vessels to narrow. Reacting to stress in unhealthy ways can raise blood pressure and increase the risk of heart attack and stroke. So counting resting HR and HR after inducing stress in the form of left arm local ischemia may help in assessing cardiovascular health.
