Idiopathic inflammatory myopathies are rare connective tissue disorders, in which inflammatory process affects mainly skeletal muscles leading to their progressive weakness. However internal organs can be affected as well, deteriorating the course of disease. We present cases of two patients with cardiac manifestations as predominant symptoms of idiopathic inflammatory myopathies. In both cases arrhythmia was the leading symptom preceding diagnosis of myositis.
