永久心律調節器裝置於患先天性完全房室傳導阻滯幼兒:一例報告

Permanent Pacemaker Implantation in a Young Child with Congenital Complete Atrioventricular Block: A Case Report

摘要


本文報告一例,15個月男童,因數度昏厥入受診療。理學檢查,體重低於正常兒的3個百分位,心率緩慢(每分鐘50次),沒有心雜音,右肋下可摸到2指寬的肝臟;心電圖呈完全房室傳導阻滯,超音波心圖及心導管血管攝影,沒發現先天性心臟異常,經裝永久性人工心律調節器,心跳調節於每分鐘90;後後病兒心律穩定,經4年追踨,狀況良好。

Congenital atrioventricular block is a congenital disorder of the cardiac conducting system. Pacemaker implantation is the treatment of choice for patients with congenital A-V block if prior medical treatment fails. The criteria for pacemaker implantation in infants and children are (1) frequent syncope (2) heart failure (3) ventricular rate below 55 beats/min (4) ventricular arrhythmia (5) QRS widening in the ECG (6) moderate to severe exercise intolerance. Our experience with a 15-month-old male child is herein presented. The patient suffered from frequent attacks of upper respiratory tract infection, bradycardia and complete A-V block as found on electrocardiograms. At 15 months old, he was admitted again due to respiratory tract infection and several attacks of syncope. Stokes-Adams syndrome was noted several times despite medical treatment. Following implantation of a VVI mode epicardiac pacemaker, the patient’s condition, including resistance to heart failure and respiration, were improved dramatically. He was followed up regularly for 4 years, his heart beat remaining stable.
