A 12-lead ECG was recorded: There is sinus rhythm with RBBB and right axis deviation. Guide to this image: 30 minutes later, at 31 C, this ECG was recorded: The RBBB has resolved. Osborn waves persist The next day, this ECG was recorded at a normal temperature: Peak hs troponin I was 650 ng/L Day 1 echo ECMO flow 2.9
