摘要
近年来,右室肥厚心电图诊断研究领域出现了许多新进展。Van Bommel等提出了心力衰竭合并左束支阻滞患者诊断右室扩大的心电图标准,即aVR导联终末正向波(晚R波),所有肢体导联QRS波低电压(<0.6 mV)和V5导联R/S<1。RV1>0.6 mV,V1导联R/S>1,RaVR>0.4 mV,PⅡ>0.25 mV这4项标准有助于明确肺动脉高压患者是否存在右室肥厚。最近的MESA-RV研究提示,应用传统心电图标准诊断轻度右室肥厚特异性较高,但敏感性较低。
Inrecentyears,manynewadvanceshaveariseninthediagnosisandresearchof ECG of right ventricular（RV）hypertrophy.In order to determine RV dilatation in patients with heart failure and left bundle branch block,Van Bommel et al proposed three ECG diagnostic crite-ria,which included the presence of terminal waves in forward direction（late R-wave）,low voltages （〈0.6 mV）of QRS complex in all limb leads and the ratio of R/S〈1 in lead V5 .Furthermore, the four ECG diagnostic criteria including RV1〉0.6 mV,R/S〉1 in V1 lead,RaVR 〉0.4 mV and PⅡ〉0.25 mV proved to be useful in determining RV hypertrophy in patients with pulmonary arterial hypertension.Recent MESA-RV study suggested that in diagnosing mild RV hypertrophy,traditional ECG screening criterion had high specificity and yet low sensitivity relatively.
