6例完全性房室传导阻滞(Ⅲ°A-VB)希氏束电图显示,1例为希氏束远端阻滞;1例为多层阻滞,即房室结完全性阻滞(A-H 中断)与完全性右束支阻滞、左前分支阻滞和Ⅰ度左后分支阻滞(H-V 延长);1例为希氏束近端阻滞。希氏束远端阻滞者心室率均<40次/分,均有昏厥史,2/4病人 QRS 波<0.12″,但Ⅲ°A-VB 者QRS 波未见明显延长,尚不能排除希氏束远端阻滞的可能性。4例希氏束远端阻滞者心室起搏未见室房逆传现象,可能远端阻滞的Ⅲ°A-VB 的室房逆传现象较为少见。
Six cases of complete atrioventricular block (Ⅲ ° A-VB) His bundle beam showed 1 case of His bundle distal block; 1 case of multi-block, that is, atrioventricular block complete block (AH interruption) and complete right bundle branch block, left anterior branch block and I degree left posterior branch block (HV extension); 1 case of proximal bundle sheath. His bundle beam distal block rate ventricular rate were <40 beats / min, have a history of syncope, 2/4 patients with QRS wave <0.12 ", but the QRA wave of Ⅲ ° A-VB no significant prolongation, The possibility of remote blocking of the bundle. There was no retrograde evidence of ventricular pacing in 4 patients with His bundle distraction block, and there was a rare case of retropharyngeal occlusion of Ⅲ ° A-VB in the distal block .
