摘要
为探讨阵发性室上性心动过速时复极改变与临床分型的关系,对28例房室折返性心动过速患者和22例房室结内折返性心动过速患者的心电图、食管调搏以及心内电生理检查进行回顾性分析。结果发现两组患者室上性心动过速时R-R间期差异并无显著意义(332.1±39.4ms对350±38ms,P>0.05),但在QRS波群电交替、ST-T改变方向差异均有显著意义(54％对14％,61％对27％,P<0.05)。并发现ST-T改变的导联与旁道位置有一定关系。提示分析阵发性室上性今动过速时的复极改变可作为鉴别室上性心动过速类型和旁道位置的一种新的辅助诊断方法。
To investigate relationship between changes in depolarization and its clinical phenotype in paroxysmal supraventricular tachycardial (PSVT), authors analysed data of electrocardiograms, transesophageal cardiac pacing and intracardiac electrophysiology in 28 atrioventricular reentry tachycardiac patients, It showed no significance in R-R intervals of two groups (332.1 ± 39.4vs. 350±38,P > 0.05) .But significant difference existed in QRS complex alternate and change of ST-T between two groups(14% vs. 54% ,27% vs. 61% ,P < 0.05). They also found some relationship between change of ST-T and location of pathway. It suggests that analysis of changes in depolarization in PSVT might be a new way to assist in diagnosis of types of PS VT and location of pathway.
