Figure 1. Initial 12-lead electrocardiogram recorded in the patient's home (A) and rhythm strip recordings of lead II during transportation (B) and shortly after arrival at the coronary care unit (C and D). Asterisks on panel A mark tented T waves with narrow bases. Note, that flattened P waves are discernable on panel B (arrows), but not on the following strips (C and D), which demonstrate progressive widening of the QRS complexes.
