Electrode catheter ablation may be used to treat supraventricular tachyarrhythmias refractory to medical treatment. Initially it was used to treat atrial fibrillation with rapid A-V conduction and later for ablation of para-septal abnormal bundles or ventricular tachycardia foci. A patient with advanced chronic air flow limitation developed atrial fibrillation with rapid ventricular response and heart failure. Drugs and cardioversion failed in controlling the arrhythmia. Partial electrode catheter ablation of the A-V node was followed by a decrease of ventricular rate from 170 to 90 per min associated to an improvement of heart failure.
电极导管消融术可用于治疗药物治疗无效的室上性快速心律失常。最初它用于治疗伴有快速房室传导的心房颤动，后来用于消融间隔旁异常束或室性心动过速病灶。一名患有晚期慢性气流受限的患者发生了伴有快速心室反应和心力衰竭的心房颤动。药物治疗和心脏复律未能控制心律失常。对房室结进行部分电极导管消融后，心室率从每分钟170次降至90次，同时心力衰竭有所改善。
