对25例接受射频消蚀治疗的预激综合征及阵发性室上性心动过速患者测定其治疗前后血清心脏肌钙蛋白T(cTnT)。结果发现,治疗后血清cTnT升高(P<0.05),表明射频消蚀术对心肌细胞有损伤,其损伤程度与射频消蚀时放电次数有关(r=0.59,p=0.002);但对患者心脏功能无明显影响。
Serum cardiac troponin T (cTnT) was measured before and after treatment in 25 patients with WPW syndrome and paroxysmal supraventricular tachycardia undergoing radiofrequency ablation. The results showed that serum cTnT increased (P <0.05) after treatment, indicating that radio frequency ablation could damage cardiomyocytes and the degree of injury was related to the number of discharges during radio-frequency ablation (r = 0.59, p = 0.002) No significant effect on cardiac function.
