Key result
Case report details severe LV dysfunction, concentric LVH, and preexcitation in a 16-year-old boy.
Why the study?
The interpretation of ECG findings and underlying pathology in a patient with left ventricular hypertrophy and preexcitation with severe LV dysfunction is unclear.
Case Report (n=1)

Alerts clinicians to syndromic cardiomyopathy evaluation in adolescents with myopathy and HF; leaves open specific etiology and management implications.
A 16-year-old boy with a history of intellectual disability and pathological myopia presented with worsening shortness of breath and swelling of feet of 2 months duration.On examination, he had a regular heart rate of 66 beats per minute, blood pressure of 90/60 mm Hg, jugular venous distension, S3 gallop, and bibasilar rales.Neurological examination revealed symmetric proximal myopathy.A 12-lead ECG obtained at admission is shown in Figure 1.An echocardiogram showed concentric left ventricular hypertrophy (LVH) and severe impairment of the left ventricular ejection fraction (30%).He had elevated natriuretic peptide levels and raised transaminases and required intravenous diuretics for initial heart failure stabilization.What is the interpretation of the ECG and what is the underlying pathology in our patient?Please turn the page to read the diagnosis.
