A Case of Lymphocytic Myocarditis With Complete Heart Block Requiring Permanent Pacemaker Implantation

Lymphocytic myocarditis (LM) is a rare condition with a broad spectrum of clinical presentations. Complete heart block (CHB) is an uncommon sequela. We present a case of a young man with biopsy-proven LM who presented with cardiogenic shock and went on to develop nonresolving CHB, requiring permanent pacemaker implantation.
