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 ( < 0.001). We also identified a significant regression model between the body mass index (BMI) and the FQRST ( < 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.
背景
心脏的电活动一直是许多涉及各种生理参数的研究的主题。额面 QRS-T 角（FQRST）是一种具有临床流行病学效用的先进心电图变量。本研究旨在确定 FQRST 与年轻成年人身体活动暴露之间的关系。
方法
我们记录了 124 名参与者（平均年龄 20.28 ± 2.23 岁，年龄范围 18-27 岁）的 12 导联心电图。然后，我们使用国际体力活动问卷-短表（IPAQ）测量了他们的体力活动水平（PAL），该问卷将活动分为低、中、高三类。
结果
基于 Kruskal-Wallis H 检验和曼-惠特尼 U 检验的推断分析显示，根据 PAL（<0.001）分类的三组受试者的 FQRST 存在统计学差异。我们还确定了 BMI 和 FQRST 之间存在显著的回归模型（<0.001）。
结论
年轻成年人的体力活动方式显著影响心室去极化和复极之间的一致性，这反映在 FQRST 的宽度上。此外，我们发现 FQRST 和 BMI 之间存在具有统计学意义的回归模型。
