Here is his ECG. See this articles: Heart Failure with Preserved Ejection Fraction (NEJM review) One etiology of LVH on the ECG is Hypertrophic Cardiolmyopathy (HOCM), and sometimes ECGs in patients with HOCM are specific for HOCM. But this ECG is NOT specific for HOCM. Figure-1: The ECG in today's case.

An ECG was obtained shortly after arrival: ECG 1 What do you think? The ECG has a lot of artifact, and the amplitude is very small, making interpretation challenging.

Past medical history included RBBB without other cardiac history, but old ECG was not available. As for the ECG, it could represent OMI, but RBBB is also a clue that it may be PE. But with prehospital and ED ECGs being ‘STEMI negative’, the ECG was signed off and the patient waited to be seen.
