长时间的R波峰值时间 (RWPT) 是COVID-19患者死亡率的重要指标. 这种心电图测量可以帮助分层分类肺炎病例中严重结果的风险.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 医学诊断 医学诊断 医学诊断
背景情况:
- R波峰值时间 (RWPT),也称为内在曲时间,测量心室激活.
- RWPT为心血管疾病 (如缩,缺血和导电异常) 提供预后信息.
- 升高的RWPT与各种心血管疾病有关.
研究的目的:
- 调查R波高峰时间 (RWPT) 与COVID-19肺炎重症监护室 (ICU) 患者的死亡率之间的关联.
- 为了确定RWPT是否可以作为COVID-19结果的预后标记.
主要方法:
- 对640名COVID-19ICU患者 (2021年1月 - 2022年6月) 的回顾性分析.
- 患者被分为生存 (510) 和死亡 (130) 组.
- 分析了临床数据,实验室标记物 (Troponin,LDH,CRP,D-dimer),T峰到T端间隔 (Tpe) 和RWPT.
主要成果:
- 死亡的群体年龄大得多,患上COPD的患病率更高.
- 在死者组中观察到高水平的热波,LDH,CRP,D-二次体,Tpe间隔和RWPT.
- 二进制逻辑回归确定了年龄,COPD,LDH,CRP,热血素,D-二次体,Tpe间隔和RWPT作为死亡的独立风险因素.
结论:
- 长时间的R波峰值时间 (RWPT) 是COVID-19肺炎患者死亡的重要独立风险因素.
- RWPT可以成为严重COVID-19患者风险分层的一个有价值的工具.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....
