Exercise‐induced ST‐segment changes simulating myocardial ischemia have been described in otherwise normal subjects during hyperventilation. We present the case of a 60‐year‐old man with pectus excavatum showing significant exercise‐induced “pseudo‐ischaemic” ST‐segment changes with neither coronary artery disease nor anxiety‐induced hyperventilation. We found no report of the possible causative role of a narrow antero‐posterior chest diameter in inducing “pseudo‐ischaemic” ST‐segment changes during exercise stress test in the literature.
