摘要

摘要: 目的：比较不同消融导管治疗三尖瓣环起源室性心律失常的疗效，并分析心电图特征。方法：入选三尖瓣环起源室性心律失常的射频消融患者54例，其中常规消融组21例，冷盐水灌注消融组33例。通过同步12导联心电图分析心电图特征及进行初步定位，然后进行非接触心内膜标测定位消融。结果：与常规消融组比较，冷盐水灌注消融组手术成功率较高（100.0%：90.5%，P<0.05），手术时间较短[（46.11±7.18）min：（50.98±10.03）min，P<0.05]，放电时间较短[（3.74±1.32）min：（5.10±2.30）min，P<0.01]，放电次数较少[（2.74±1.16）次：（4.86±2.00）次，P<0.01]。结论：对于三尖瓣环起源室性心律失常的射频消融，冷盐水灌注导管可能有利于提高手术成功率，缩短手术时间，体表发作心电图能对其初步定位提供帮助。

Abstract: Objective: To compare the efficacy of different ablation catheters treatment on ventricular arrhythmias originating from tricuspid annulus. Method: We selected 54 patients with radiofrequency ablation due to ventricular arrhythmias originating from tricuspid annulus.Twenty-one cases were in conventional ablation group and 33 cases were in cold saline infusion ablation group.We also analyzed the ECG characteristics and initial positioning by synchronous 12-lead ECG, then we performed radiofrequency ablation through non-contact endocardial mapping. Result: Success rate of surgery was higher(100.0% vs 90.5%, P<0.05), operative time was shorter[(46.11±7.18)min vs(50.98±10.03)min, P<0.05], discharge time was shorter[(3.74±1.32)min vs(5.10±2.30)min, P<0.01] and discharge times was less[(2.74±1.16)times vs(4.86±2.00)times, P<0.01] in cold saline infusion ablation group compared with conventional ablation group. Conclusion: In patients with ventricular arrhythmias originating from tricuspid annulus, cold saline infusion catheter may help to improve the success rate of surgery and shorten the operative time, the surface attack ECG can help to its preliminary position.
