A 54-year-old man presented with palpitations. He had no other symptoms. Physical examination revealed, with the exception of a fast regular heart rhythm (200 beats/min), no abnormalities. His ECG is shown in figure 1. Intravenous verapamil terminated the tachycardia and a second ECG (figure 2) was taken.
