Conduction and refractoriness alternans may be seen with WPW-related as well as AV Nodal-dependent reentr y tachycardias — atrial fibrillation — acute pulmonary embolus — myocardial contusion — and severe LV dysfunction. Therefore — identification of QRS alternans during a regular SVT does not prove the existence of an accessory pathway.

CT pulmonary angiogram was negative for pulmonary embolism. If the patient continues to have reperfusion, then we would expect progressive terminal T wave inversion then full T wave inversion over time in the future ECGs. Second troponin T resulted at 1,318 ng/L. Chest x-ray was read as normal. Heparin was started. Reocclusion!
