摘要
报告1例扩张型心肌病合并完全性左束支传导阻滞患者,入院后给予强心、扩管、利尿、抑制心肌重构和改善心肌代谢等治疗,住院过程中患者反复发作室颤,且心功能差,行心脏再同步化治疗除颤器(CRT-D)植入术,术后患者症状明显改善,随访近2年,超声心动图示:左室舒张末内径由70 mm缩小到42 mm,左房内径由34 mm缩小到30 mm,左室射血分数由0.35提高到0.62。患者一般状况良好,日常活动不受限制,为CRT-D超反应,由此推测出本例患者取得超反应的原因可能是CRT-D纠正了传导阻滞导致的心脏进行性扩大。
A case of dilated cardiomyopathy complicated with complete left bundle branch block was reported.After admission,the patient was treated with cardiotonic,dilatation,diuresis,inhibition of myocardial remodeling,improvement of myocardial metabolism and so on.The patient was with recurrent ventricular fibrillation during hospitalization and poor heart function,and the patient's symptoms improved significantly after CRT-D(cardiac resynchronization therapy-defibrillator)implantation.Followed up for nearly 2 years,echocardiography showed that left ventricular end diastolic dimension reduced from 70mm to 42 mm,left atrium dimension reduced from 34 mm to 30 mm,and left ventricular ejection fraction increased from 0.35 to 0.62.The patient was generally in good condition and no restrictions on daily activities,which was the CRT-D hyperreactivity.The reason for this patient's hyperreactivity might be that CRT-D has corrected the progressive enlargement of the heart caused by conduction block.
