To investigate an approach of treatment for atrial fibrillation with discrete ablation lesion, 12 dogs with experimental atrial fibrillation underwent radiofrequency catheter ablation. Atrial lesion was made at the most vulnerable site. The results showed that in 10 of 12 dogs persistent fibrillation could be ablated. There was no significant change in sinus heart rate, P wave duration, and corrected sinoatrial node recovery time (cSNRT). The results suggested that paroxysmal atrial fibrillation could be eliminated...

To investigate an approach of treatment for atrial fibrillation with discrete ablation lesion, 12 dogs with experimental atrial fibrillation underwent radiofrequency catheter ablation. Atrial lesion was made at the most vulnerable site. The results showed that in 10 of 12 dogs persistent fibrillation could be ablated. There was no significant change in sinus heart rate, P wave duration, and corrected sinoatrial node recovery time (cSNRT). The results suggested that paroxysmal atrial fibrillation could be eliminated by point ablation of the lesion, and that trigger activity might be involved in the mechanism of atrial fibrillation.

Objective To evaluate the efficacy and safety of idiopathic right ventricular tachycardia(VT) with radiofrequency catheter ablation.Methods 78 patients with idiopathic ventricular tachycardia underwent radiofrequency catheter ablation and follow-up.The VTs with a left bundle branch block-type QRS morphology and inferior axis suggested that they originated from right ventricular outflow tract (RVOT).The target site was determined by pace mapping (QRS complex during pacing is the same as spontaneous VT).Results Ventricular tachycadia was successfully ablated in 73(73/78,93.5%)patients.33%,41% and 26% of the ablated sites located in anterior,middle and posteror septum,respectively.From clinical manifestations and electrophysiological study,RVOT-VT can be divided into a simple-VT and VPCs(ventricular premature constricts)-VT patterns.The simple-VT (35 patients)is possibly related to trigger activity or reentry,VPCs-VT (43 patients) related to trigger or automatic activity.Ventricular tachycardia recurred in 3 patients during the follow-up of 6 months to 7 years.Except that one patient developed right bundle branch block during ablation,no ablation-related complications occurred.Conclusion The results suggest that radiofrequency catheter ablation is a safe and effective method for idiopathic ventricular tachycardia originating from right ventricular outflow tract.

目的 :探讨缺血再灌注心律失常机制及地尔硫、汉防己甲素对其的干预作用。方法 :采用玻璃微电极技术以豚鼠乳头肌为研究对象观察模拟缺血再灌注过程中动作电位的变化及地尔硫、汉防己甲素对其的影响。结果 :对照组动作电位时程 (APD50、APD90)、有效不应期 (ERP)、动作电位振幅 (APA)随缺血时间延长而降低 ,含氧台氏液复灌20min恢复。5μmol/L地尔硫和10μmol/L汉防己甲素可缩短APD90、ERP ,对APA无影响。缺血过程中不能减少ERP、APD的缩短程度 ,但相对延长ERP ,减少再灌注心律失常发生。结论 :触发或自律性异常是再灌注心律失常的发生机制 ,钙离子超负荷发挥作用。地尔硫和汉防己甲素可减少再灌注心律失常的发生 ,但有潜在致折返性心律失常危险。
