POLYMYOSITIS COMPLICATED WITH COMPLETE ATRIOVENTRICULAR BLOCK: A CASE REPORT AND LITERATURE REVIEW

Background: Cardiac involvement in polymyositis is often asymptomatic. Electrocardiogram (ECG) remains a cornerstone for the screening of conduction disturbances and other electrocardiographic abnormalities. Case presentation: We report the case of a 35 year-old-woman with polymyositis complicated with a complete atrioventricular block 10 years after the beginning of her symptoms. She was admitted to the hospital for syncope and benefited from a pacemaker insertion without incident. Conclusion: Cardiac effects of polymyositis are associated with poor prognosis and might appear in patients in remission of the disease.
