Necrotizing myopathy presenting as congestive heart failure and life-threatening ventricular arrhythmias: a case report.

ABSTRACT:

Background

Necrotizing autoimmune myopathy is a rare subtype of idiopathic inflammatory myopathy; however, it can be associated with fatal cardiac manifestations.

Case summary

A 58-year-old female patient was referred for congestive heart failure with dysrhythmia. Electrocardiograms showed ventricular arrhythmias of various QRS complex morphologies and coupling intervals with beat-to-beat differences. Despite optimal medical therapy for heart failure, the patient was admitted for the progression of dyspnoea and generalized motor weakness. The burden of non-sustained ventricular tachycardia gradually increased, and ventricular fibrillation eventually occurred. In view of a differential diagnosis of an inflammatory myocardial diseases such as sarcoidosis, a cardiac biopsy was
