A 50 year old woman with no evidence of structural heart disease was referred for ectopic incessant repetitive atrial tachycardia uncontrolled by medical therapy. Intracavitary and transesophageal simultaneous recordings revealed the earliest atrial electrical activity to be located in the left atrium. Intraoperative electrophysiologic mapping demonstrated that the site of earliest atrial activation was in a small diverticulum of the left atrial appendage. Excision of the appendage and isolation of left atrium was carried out with restoration of sinus rhythm. The patient was arrhythmia-free till 24 months later. Surgical treatment appears to be an effective therapeutic option for drug-resistant ectopic atrial tachycardia.
一名50岁无结构性心脏病证据的女性因药物治疗无法控制的异位持续性反复房性心动过速前来就诊。心腔内和经食管同步记录显示最早的心房电活动位于左心房。术中电生理标测表明最早的心房激动部位位于左心耳的一个小憩室内。切除心耳并隔离左心房后恢复了窦性心律。该患者在24个月后一直未出现心律失常。手术治疗似乎是耐药性异位房性心动过速的一种有效治疗选择。
