Dr. Smith's ECG Blog

CT angiogram chest: no aortic dissection or pulmonary embolism. He spent several days in the PICU, undergoing workup including: Serial troponins: rising from 5,700 ng/L (unknown if I or T) to greater than 25,000 ng/L (greater than the lab's upper limit of reporting). No further troponins were measured.

His initial high sensitivity troponin I returned at 1300 ng/L and given that his cardiac workup was otherwise unremarkable, a CT was obtained to evaluate for pulmonary embolism and aortic aneurysm or dissection but this too was unrevealing. Another EKG was also obtained. ECG at time 82 minutes: What do you think?
