A 42-year-old man presented to the emergency department with a history of central non-radiating chest pain lasting for 25 min, 2 h back. The pain was associated with vomiting and sweating, and subsided spontaneously. He was pain free at the time of presentation. He had had similar episode 3 weeks previously, which lasted less than a minute while he was rock climbing. There was history of hyperlipidaemia for which he was not taking any medication. His physical examination including cardiac evaluation was within normal limits. The cardiac enzymes were also normal. His electrocardiogram on admission is shown in Fig. 1. What would your diagnosis be and what would you expect to find on cardiac catheterisation?
