Abstract
A 55 year old healthy man with chronic bifascicular block (right bundle branch block and left anterior hemiblock) had a near syncopal episode. A treadmill test showed exercise induced Mobitz type II AV block manifested clinically by paradoxical slowing of the heart rate and decreased blood pressure. True His Purkinje block and pseudo AV block due to His extrasystoles were documented by an electrophysiological study.
摘要
一名55岁健康男性，患有慢性双分支阻滞（右束支传导阻滞和左前分支阻滞），曾发生一次接近晕厥的发作。平板运动试验显示运动诱发的莫氏Ⅱ型房室传导阻滞，临床表现为心率反常减慢和血压下降。电生理研究证实存在真正的希氏束-浦肯野纤维阻滞以及由希氏束期前收缩引起的假性房室传导阻滞。
