概括
在儿科心电图 (ECG) 期间将肢体电极放置在干上会改变测量结果,特别是在较矮的儿童中. 这种修改的心电图位置可能导致误解心脏异常.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 电心电图是指心电图.
- 生物医学工程 生物医学工程
背景情况:
- 儿童的标准心电图 (ECG) 通常使用干四肢电极放置.
- 这种修改的儿科心电图配置对诊断准确性的影响尚未得到充分研究.
研究的目的:
- 为了在健康儿童中比较标准的四肢主导心电图与干四肢主导心电图.
- 评估孩子的身高如何影响这两种心电图配置之间的一致性.
主要方法:
- 185名儿童 (5-18岁) 进行了两次12线心电图:一个标准的,一个带有干四肢的.
- 通过使用Bland-Altman图表和高度依赖错误分析,对17个ECG参数的一致性进行了评估.
主要成果:
- 干位置将QRS和P波轴向右移动,并改变了前幅度.
- PR间隔和QRS持续时间显示一致,但QTc间隔的一致范围很大.
- 在矮小的儿童中,测量误差更大,并且随着参数大小的增加而增加.
结论:
- 经过修改的干四肢电极放置显著改变了儿科心电图信号.
- 这可能导致心脏异常的错误分类,特别是在较短的儿童或接近正常限度的儿童中.

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.

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.
