本文采用Lewis室早诊断标准,并排除多形、多源及联律间期不等之室早,对101例诊断为单灶性室早患者的心电图进行了分析研究.结果表明完早联律间期跟窦性心动周期呈正相关(r为+0.96),并提出了室早联律间期随心动周期变化而变化特征的新指标——变化率的概念,且认为在描述室早QRs波群方末向与T波方向关系时,宜用“室早T波方向与QRs波群终未向量方向相反”一语为要.从而,为进一步加深时室早本身及其和临床关系的认识提供了新的线索.
In this paper, the diagnostic criteria for early diagnosis of Lewis chamber, and exclude pleomorphic, multi-source and associated interventricular septal abnormalities, 101 cases of patients diagnosed as early single ECG were analyzed. The interval was positively correlated with sinus rhythm (r = +0.96). The concept of rate of change was also proposed. The concept of rate of change It is appropriate to use the phrase “the direction of early T-wave in the ventricle is opposite to the direction of the final unvector of the QRs complex” in the relationship between the end-group direction and the T-wave direction.Therefore, to further deepen the knowledge of early ventricular tachycardia itself and its clinical relationship Provide new clues.
