电心电图 (ECG) 可以帮助诊断肺动脉高血压 (PAH) 在患有严重三回 (TR) 的患者. 特定的ECG标准,包括R:S V1比率和R V1/2 + S I/aVL - S V1,有助于区分PAH与孤立的TR.
科学领域:
- 心脏病学 心脏病学
- 医学诊断 医学诊断 医学诊断
背景情况:
- 心声学对于查肺高血压 (PH) 使用三回 (TR) 速度至关重要.
- 严重的TR可能导致低估肺动脉压力,可能掩盖PH.
- 在严重的TR中,准确的PH诊断需要探索补充诊断工具.
研究的目的:
- 评估心电图 (ECG) 在预测严重TR患者肺动脉高血压 (PAH) 的有用性.
- 为了确定特定的ECG标准表明PAH在严重TR的背景下.
- 评估心电图在区分PAH与分离的TR (iTR) 中的作用.
主要方法:
- 对83名患有严重TR的患者进行分析,这些患者接受了右心脏导管治疗.
- 在患有PAH (n=58) 和孤立TR (iTR,n=25) 的患者之间,ECG发现的比较.
- ROC分析以确定最佳的ECG值来预测PAH.
主要成果:
- 特定的心电图标准,包括R:S V1 > 1.5,最大R V1/2 +最大S I/aVL - S V1 > 3 mm,和S I/R I > 0.71,与PAH相关.
- 这些标准显示了显著的AUC值 (0.74-0.79) 和不同的灵敏度/特异性.
- 心房的存在预测了 iTR,敏感度为76%和特异性为81%.
结论:
- 电脑电图分析为在重症TR患者中诊断PAH提供了宝贵的见解.
- 前庭动表明孤立的TR,而特定的ECG电压标准则有利于PAH的二次TR.
- 电脑心电图可以提高诊断的准确性,指导进一步的肺高血压的侵入性评估.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

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...
