Background: Measurement of Systolic Time Intervals (STIs) is a non-invasive and convenient way of assessing left ventricular electro-mechanical activity in health and disease. In this study, we assessed some of the parameters of STIs in a group of healthy young adults from the first-year students of a government medical college in West Bengal, India. Objectives: To assess QT, QS2 and their ratio and compare them between the girls and boys and to create a regional database in comparison to the international values. Methods: IX-TA-220 multichannel recorder was used to record Electrocardiogram (ECG), Heart sound (Phonocardiogram) and Carotid pulse tracing in lying down position at noon and in the postabsorptive stage after the last meal. Results: Mean values of the proposed parameters were analysed by Microsoft Excel software and compared between the boys and girls and also with available international reference values. QS2-Index (QS2-I) was calculated using Wandermann equation6. There were significant differences in the mean values of QT, QS2-I and QT/QS2 between the two sexes. Also, the observed values of QS2-I were slightly longer than international standards. Conclusion: Observed deviation in the duration of systolic intervals from the available international data might be due to geographical and genetic differences. The difference was observed even between the two sexes. Hence the diagnosis of probable cardiac complications should be done based on regional as well as age __ampersandsignamp; sex-specific references.
