目的:探讨阵发性室上性心动过速患者经导管射频消融术治疗后的临床效果。方法:56例阵发性室上心动过速患者,常规行心腔内电生理检查明确室上性心动过速类型。左侧房室旁道参与的折返性心动过速消融时采用主动脉瓣逆行途径或穿刺房间隔途径标测和消融,右侧房室旁道参与的折返性心动过速经右股静脉标测和消融,房室结折返性心动过速消融采用下位法消融慢径路。结果:56例阵发性室上性心动过速(PSVT)患者中房室结折返性心动过速39例(69.6%)、房室折返性心动过速17例(30.4%),其手术即时成功率为96.4%(54/56),平均手术时间为(108.6±20.5)min,术后复发率1.8%(1/56)。56例患者中出现手术并发症2例(3.6%),其中1例出现短暂性可逆性Ⅲ度房室传导阻滞,其余患者均无瓣膜损伤、心包填塞和死亡等严重并发症。结论:经导管射频消融治疗阵发性室上性心动过速是安全有效、成功率高、并发症少的方法。
Objective: To investigate the clinical effect of catheterized radiofrequency catheter ablation in patients with paroxysmal supraventricular tachycardia. Methods: 56 cases of patients with paroxysmal supraventricular tachycardia, routine electrophysiological examination of the heart to identify the type of supraventricular tachycardia. Left atrioventricular reentrant involved in reentrant tachycardia ablation by aortic valve retrograde approach or puncture atrial septal approach mapping and ablation, right atrial accessory pathway involved in reentrant tachycardia by the right femoral vein And ablation, atrioventricular nodal reentrant tachycardia ablation downstream method ablation slow path. Results: Among the 56 patients with paroxysmal supraventricular tachycardia (PSVT), 39 (69.6%) had atrioventricular nodal reentrant tachycardia and 17 (30.4%) had atrioventricular reentrant tachycardia The success rate was 96.4% (54/56), the average operation time was (108.6 ± 20.5) min, postoperative recurrence rate was 1.8% (1/56). Two of 56 patients had surgical complications (3.6%). One of them had transient reversible grade III atrioventricular block, and the rest had no serious complications such as valve injury, tamponade and death. Conclusions: Transcatheter radiofrequency catheter ablation of paroxysmal supraventricular tachycardia is a safe and effective method with high success rate and less complications.
