A 76-year-old man presented to the Emergency Department after a
syncopal episode at home.
He recovered spontaneously but his wife, who witnessed the
episode, insisted that he go to hospital. His only recollection of
the episode was that he suddenly felt light-headed and then he
passed out. He said that the episode was not preceded by chest pain
or breathlessness. He had a previous history of an anterior
myocardial infarction (MI) three months previously.
On examination, he appeared well. His pulse was 80 beats per
minute and regular with a blood pressure of 110/70 mmHg. He had a
diffuse apex beat. The heart sounds were normal with no added
sounds or murmurs.
A 12-lead ECG showed ST segment elevation in leads V3 to V6 and
frequent ventricular extrasystoles. A serum troponin-T, taken
twelve hours after the episode, was normal.
What is the most likely diagnosis?
