Abstract

Background: The heart’s electrical activity has been the subject of numerous research concerning various physiological parameters. The frontal QRS-T angle (FQRST) is an advanced ECG variable with clinical epidemiological utility. This study aimed to determine the relationship between FQRST and physical activity exposure among young adults. Methods: We recorded the ECG with 12 leads of 124 participants (mean age 20.28 ± 2.23 years, age range 18–27 years). Next, we measured their physical activity level (PAL) with the International Physical Activity Questionnaire—Short Form (IPAQ), which categorizes activity into three classes: low, moderate, or high. Results: An inferential analysis, based on the Kruskal-Wallis H test and Mann–Whitney U test, revealed a statistically significant difference in FQRST between the three groups of subjects, classified by their PAL (p < 0.001). We also identified a significant regression model between the body mass index (BMI) and the FQRST (p < 0.001). Conclusions: The physical activity regime of young adults significantly influences the concordance between ventricular depolarization and repolarization, reflected in the FQRST’s width. Also, we found a regression model between FQRST and BMI with statistical significance.
