Four personal cases of exercise-induced conduction defects occurring during stress testing are reported. The significance of these changes is discussed in the light of the authors' observations and of the cases published in the literature. The development of atrioventricular block is usually related to pre-existing disease of the conduction system, whilst left anterior or posterior hemiblock is usually due to transient ischaemia related to significant stenosis of the coronary artery responsible for the vascularisation of the relevant bundle branch (usually a proximal stenosis of the left anterior descending artery). Complete left bundle branch block may be due to a number of conditions (including chronic ischaemic heart disease).
报告了4例在压力测试期间发生运动诱发传导缺陷的个人病例。根据作者的观察以及文献中发表的病例，讨论了这些变化的意义。房室传导阻滞的发生通常与传导系统的既往疾病有关，而左前或后半束支传导阻滞通常是由于与负责相关束支血管化的冠状动脉严重狭窄相关的短暂性缺血（通常是左前降支近端狭窄）。完全性左束支传导阻滞可能由多种情况引起（包括慢性缺血性心脏病）。
