Atrial standstill in suspected isolated cardiac sarcoidosis

Abstract

Most of the abnormal cardiac conduction system findings are atrial tachyarrhythmias in cardiac sarcoidosis. However, atrial standstill as a sick-sinus syndrome could be complicated in the case of diffuse atrial fibrosis. Herein, we present an interesting and valuable case of atrial standstill with suspected isolated cardiac sarcoidosis.
