2例均为扩张型心肌病合并完全性左束支传导阻滞(CLBBB),NYHA心功能Ⅲ级,在接受心脏再同步化过程中,左室电极不能到达靶静脉,改用His束起搏治疗。1例57岁男性患者,随访10个月,临床症状明显改善,QRS波恢复正常,左室及左室射血分数恢复正常。另1例50岁的男性患者,随访12个月,临床症状明显改善,QRS波恢复正常,左室及左室射血分数恢复正常。
2 cases were dilated cardiomyopathy with complete left bundle branch block (CLBBB), NYHA cardiac function grade Ⅲ. During cardiac resynchronization, the left ventricular electrode could not reach the target vein and switch to His bundle treatment. A 57-year-old male patient was followed up for 10 months. The clinical symptoms were significantly improved, the QRS wave returned to normal, and left ventricular and left ventricular ejection fraction returned to normal. Another case of 50-year-old male patient was followed up for 12 months, clinical symptoms improved significantly, QRS wave returned to normal, left ventricular and left ventricular ejection fraction returned to normal.
