本文报告了1982年11月至1984年9月间,经静脉心内膜心肌活检73例的心电图监护结果。右心活检时,活检钳在心腔和心壁的定位必须经心腔心电图确定。将活检钳尾端通过导线连接于心电图机上胸前导联电极,即可连续描记心腔心电图。活检钳从右房上部至右室下部的行程中P波和QRS波形态可出现进行性变化,一旦活检钳紧贴心室壁,心腔心电图ST明显抬高,为此,心腔心电图能协助活检钳定位。本组有45例在心肌活检操作过程中,出现一过性心律失常,一般不出现临床症状。
This article reports the electrocardiographic surveillance of 73 patients with transthmatic endomyocardial biopsy from November 1982 to September 1984. Right heart biopsy, biopsy forceps in the heart and heart wall positioning must be confirmed by the heart chamber electrocardiogram. The biopsy forceps through the end of the wire connected to the electrocardiogram chest lead electrode, continuous tracing cardiocardiography. Biopsy forceps from the right atrium to the lower part of the right stroke in the lower reaches of the journey of P wave and QRS wave morphology may occur changes, once the biopsy forceps close to the ventricular wall, ST-cardiac electrocardiogram significantly elevated, therefore, intracardiac electrocardiography can assist in biopsy Clamp positioning. This group of 45 patients during myocardial biopsy, a transient arrhythmia, the general does not appear clinical symptoms.
