“…One limitation of the present report relates to the absence of an electrophysiological study (EPS). As previously described, most cases of reported exercise induced CAVB are infranodal [10,11,17], though there are also reports describing a supranodal block [8], suggesting the utility of EPS to ascertain the specific site in question [8,10,13]. One possible explanation for exercise induced CAVB, as previously described [10,11,13], derives from the differences in the conduction properties and refractory periods between the AV node (with increased conduction and decreased refractory period associated with exercise) and the His-Purkinje system (not under autonomic control, and as such whose refractory period is not substantially altered by exercise).…”

Exercise stress testing can have a central role in the assessment of cardiovascular disease. Contemporary data, however, has highlighted the added value of imaging modalities over the exercise electrocardiogram in the investigation of coronary artery disease. Given the physiological changes associated with exercise and the possibility to address other parameters such as rhythm changes and the chronotropic response, exercise stress testing with continuous electrocardiographic monitoring can still have an important place in contemporary clinical practice. We report the case of a complete atrioventricular block associated with exercise and discuss the current role of exercise stress testing with continuous electrocardiographic monitoring in this entity.
