Abstract:

Abnormalities of conduction forms a minor diagnostic criterion in modified Jones criteria. Our patient was diagnosed as rheumatic fever on basis of clinical evidence and positive ASLO. Infective endocarditis was ruled out by negative blood cultures and echocardoigram. During hospital stay she had transient extraordinary prolonged PR interval which recovered uneventfully. 24 hour holter did not reveal any atrioventricular conduction abnormality. To best of our knowledge such isolated cases of marked PR prolongation has never been reported

Keywords:

rheumatic fever, PR interval, atrioventricular conduction
