Diagnosing subtle forms of potentially life-threatening diseases.

ithin the first few months of my practice, I changed the ife of a young physician referred for right ventricular (RV) utflow tract ventricular tachycardia (VT) with the diagnois of arrhythmogenic right ventricular cardiomyopathy/ ysplasia (ARVC/D). This was an uncomfortable moment, ut not one nearly as bad as “the cardiologist’s worst ightmare” (1), making the opposite mistake of missing a ife-threatening diagnosis due to mimicking of a much more ommon benign condition. How often do we make that istake? Can it be prevented?
