Two new cases of exercise related left-bundle branch block are reported in this study. They should be added to the twenty established and published cases. Comparison opens the way to discussion of the mechanism of onset. Ischemia is often accused, although no exploration has been able to demonstrate its responsibility in the origin of the problem. These two cases have novel features, particularly in describing the first case of painful exercise related bundle branch block in a subject twenty-three years of age. Ischemia linked to epicardial coronary lesions cannot be held responsible, but the possibility of micro-circulatory ischemia is suggested.
本研究报告了两例与运动相关的左束支传导阻滞新病例。应将它们添加到已确立并发表的20例病例中。对比为探讨发病机制开辟了道路。尽管尚无探索能够证明缺血在该问题起源中的责任，但缺血常被归咎于此。这两例病例有新的特点，特别是描述了一名23岁受试者中首例与疼痛性运动相关的束支传导阻滞。与心外膜冠状动脉病变相关的缺血不能被认定为病因，但提示了微循环缺血的可能性。
