摘要:
应用高频心电图(HFECG)观察66例阵发性室上性心动过速患者射频消融(RFCA)前、后的高频切迹(HFN)的变化,以了解RFCA对心肌的损伤情况。结果显示 ①RFCA术后高频切迹(HFN)显著增加(9.6±3.5 vs 23.3±6.2,P<0.01);②累计放电能量越高,放电次数越多,HFN增加越明显(17.8±5.9 vs 12.0±5.1,17.0±5.0 vs 11.6±5.2,均为P<0.01);③心房放电组的累计放电能量和放电次数明显高于心室放电组(13760±8572 J vs 2988±1371 J,14.9±12.8 次vs 3.4±2.7次,均为P<0.01),而两组所造成的HFN变化却无明显差异(14.4±5.7 vs 12.0±5.6,P>0.05)。结论 HFECG可以早期而敏感地反映RFCA对心肌的损伤,影响心肌损伤程度的因素有累计放电能量、放电次数和放电部位。
Abstract:
To study myocardial injury after radiofrequency catheter ablation (RFCA),high frequency electrocardiogram (HFECG) was analysised in 66 patients undergoing RFCA. The result showed that high frequency notching (HFN) significantly increased after RFCA (9.6±3.5 vs 23.3±6.2,P<0.01); HFN of the group with more accumulated power and greater number of power release during RFCA was significantly greater than that of the group with less accumulated power and smaller number of power release (17.8±5.9 vs 12.0±5.1,17.0±5.0 vs 11.6±5.2,P<0.01,respectively). The accumulative power and the number of energy application in the atrium ablated group were significantly higher than those in the ventricle ablated group ( (13760±8572 J vs 2988±1371 J,14.9±12.8 vs 3.4±2.9,P<0.01,respectively), there was not any difference in the change of HFN between the two groups ((14.4±5.7 vs 12.0±5.6,P>0.05). These findings suggest that HFECG may sensitively monitor the myocardial injury induced by RFCA, and the level of myocardial injury was related to the accumulated power,the number of energy application and the position in RFCA.
