title: A case of dilated cardiomyopathy with abnormal atrioventricular conduction 5 years before the appearance of left ventricular systolic dysfunction.
abstract: The first manifestation of dilated cardiomyopathy is usually dyspnea as a result of left heart failure. In this report we describe an unusual patient with third-degree atrioventricular (AV) block unaccompanied by left ventricular dysfunction. Severe left ventricular dysfunction occurred 5 years after the implantation of a permanent pacemaker. We conclude that AV block should not be overlooked as an initial clinical manifestation of dilated cardiomyopathy.
