In 2011, we reported the case of an asymptomatic athlete with a family history of sudden death (unknown cause), presenting with deep TWI, who was provided with medical clearance for competitive sport due to lack of a definitive diagnosis of cardiac pathology.1 Three months after receiving clearance, however, the athlete had a transient loss of consciousness during exercise (training at his club) and was found to have a serious rhythm disturbance during intensive exercise on follow-up graded exercise testing.
