We present the case of a patient with ischemic heart disease and intermittent left bundle branch block, reproducibly induced by laughter. Following treatment of ischemia with successful deployment of a drug-eluting stent, no further episodes of inducible LBBB were seen. Transient ischemia, exacerbated by elevated intrathoracic pressure during laughter, may have contributed to onset of this phenomenon.
我们报告了一例缺血性心脏病和间歇性左束支传导阻滞患者的病例，该患者的左束支传导阻滞可由大笑诱发且具有可重复性。在缺血部位成功放置药物洗脱支架治疗后，未再出现可诱发的左束支传导阻滞。大笑时胸腔内压力升高导致短暂性缺血，可能促成了这种现象的发生。
