有心电图早复极波的人群中,仅少数伴有恶性室性心律失常或心脏性猝死,因此,为有早复极波患者寻找危险分层的指标已成为该领域的热点。最近,Roten等在《Heart Rhythm》杂志2016年第4期发表的文章指出,T波低平及T波和R波幅度的比值也能用于该危险分层。研究比较了92例有早复极波又合并室颤的患者和247例无症状而有早复极波患者的心电图。研究指标包括J波振幅、QTc值、Ⅱ导联和V5导联的T波振幅及T波/R波振幅(T/R)的比值。结果发现
Of the population with early polar wave of electrocardiogram, only a few are associated with malignant ventricular arrhythmia or sudden cardiac death. Therefore, finding an index of risk stratification for patients with early repolarization wave has become a hot topic in this field. Recently, an article by Roten et al. In Heart Rhythm magazine, Issue 4, 2016, pointed out that the ratio of T wave dip and T wave to R wave amplitude can also be used for this hazard stratification. The study compared 92 patients with early repolarization and ventricular fibrillation and 247 asymptomatic patients with early repolarization ECG. The study included J wave amplitude, QTc value, T wave amplitude and T wave / R wave amplitude (T / R) ratio between lead II and lead V5. turn out
