射频消融是通过造成心肌局部凝固性坏死而达到消融异常传导通路的目的,因而必然存在心肌损伤.本文通过对心脏肌钙蛋白T(cardiac troponinT,cTnT)及心肌酶(CK-MB)等心肌损伤敏感血清标志物的观察,探讨导管射频消融术中心肌损伤的影响因素.1 资料与方法1.1 对象1998～1999年因阵发性室上性心动过速,于本
Radiofrequency ablation (RFA) is a method to induce ablation of abnormal conduction pathways by causing local coagulation necrosis of the myocardium.Therefore, myocardial injury is bound to exist.This study investigated the effects of cardiac troponin T (cTnT) and myocardial enzymes (CK-MB) Sensitive serum markers observed catheter radiofrequency ablation of myocardial injury in the influencing factors.Materials and methods1.1 object 1998 to 1999 due to paroxysmal supraventricular tachycardia in this
