In this case, in spite of the story of atypical chest pain and an initial cardiogram that the EKG machine interpreted as probable LVH with secondary repolarization changes, the patient evolved a non-Q MI. An angiogram showed a significant narrowing in the left anterior descending artery.

This is one of a series of three cardiograms. The first (below) was taken at 99/8/9@13h36hrs , the second at 99/08/09@22h20, and the third at 99/08/10@7h18.

Rate (/min) 56 QT (ms) 369
pr (ms) 153 QRS axis (degrees) -11
QRS (ms) 85
