概括
使用性别特异的QRS电压的新型心电图 (ECG) 标准可以改善运动员对病态左心室缩的检测. 这些更新的标准提高了敏感性,同时保持了运动员查的特异性.
科学领域:
- 心脏病学 心脏病学
- 运动医学 运动医学
- 电心电图是指心电图.
背景情况:
- 左心室缩是运动员常见的心电图发现.
- 现有的基于振幅的标准通常会产生错误的阳性结果,需要改进选方法.
研究的目的:
- 重新评估心电图 (ECG) 标准,用于对运动员进行左心室缩的查.
- 使用大型数字心电图数据库将QRS振幅测量和人口因素纳入.
主要方法:
- 从2010年到2021年,对9254名年轻运动员 (12至35岁) 的心电图进行了回顾性分析.
- 评估的R和S波幅 (R的第99个百分点,S的第一个百分点),Sokolov-Lyon (SL) 和四肢 (LL) 评分.
- 在单变量和多变量分析中根据性别,运动,年龄,阶级,BMI和心率进行调整.
主要成果:
- 在R波和S波电压中观察到显著的性别差异.
- 与女性相比,男性运动员的SL和LL得分较高.
- 性别是SL和LL分数的最强预测因素,其他因素的影响较弱.
结论:

1.7K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
