It was from a patient with chest pain: Note the obvious Brugada pattern. She has not yet been seen by electrophysiology or had further genetic testing for Brugada syndrome. The elevated troponin was attributed to either type 2 MI or to non-MI acute myocardial injury. There is no further workup at this time.

The patient denied any chest pain whatsoever, and a troponin at zero and 2 hours were both undetectable. A score including ECG pattern, early familial SCD antecedents, inducible electrophysiological study, presentation as syncope or as aborted SCD and SND had a predictive performance of 0.82. and proband status (HR 2.1).
