Abstract
Heart rate is a measurement of how many times your heart beats in one minute. Resting heart rate can be an important measure of the health of heart muscle. Heart rate is the principal indicator used in field survey / study, now it denoted as a biomarker. Biomarker not only serve as traditional predictors of prognosis, it can also help to identify high-risk; therefore, the use of heart rate (HR) as a biomarker in assessment of cardio vascular disease and cardio vascular fitness status also. The present workshop will elaborate the calculation process of different cardiac strain indices and how these cardiac strain indices may alter the workload of an individual. Further elaboration along with the calculation process will be made during the presentation.
