interesting findings. Q waves usually represent scar tissue, yet there are numerous causes for the develop-ment of abnormal Q waves that are not due to myocardial infarction.1 Limited information is available to explain readily the transient nature of Q waves induced by exercise. We pre-sent an ECG illustrating a less appreciated cause of Q wave.
