Another factor to be considered, according to Chou’s textbook, is that many patients have dual AVN physiology and conduction is preferential down the fast pathway. It doesn’t meet any conventional STEMI criteria, but there is patently obvious increased area under the curve. The shortened PR-interval is probably an accessory pathway.”

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Look at the aortic outflow tract.
