An infant with DiGeorge syndrome, multiple comorbidities, and truncus arteriosus type II underwent repair complicated by heart block necessitating placement of a dual-chamber bipolar pacing system with right ventricular leads and subsequent resynchronization with placement of left ventricular apical pacing leads. Resynchronization therapy improved QRS duration from 180 ms to 100 ms and ejection fraction from 25% to 54% over the course of 4 weeks with gradual return to normal function and eventual discharge.
一名患有迪乔治综合征、多种合并症且为II型共同动脉干的婴儿接受了修复手术，术后并发心脏传导阻滞，需要植入带有右心室导线的双腔双极起搏系统，随后通过植入左心室心尖起搏导线进行再同步化治疗。在4周的时间里，再同步化治疗使QRS时限从180毫秒缩短至100毫秒，射血分数从25%提高到54%，功能逐渐恢复正常并最终出院。
