ECG and histological findings of the heart in a 63-year-old man with metastatic melanoma who developed fulminant lymphocytic myocarditis following initial doses of nivolumab and ipilimumab and who developed complete heart block.36 Despite intense treatment (intravenous methylprednisolone 1 g/kg daily for 4 days plus infliximab 5 mg/kg), fatal complete heart block occurred. Initial right bundle branch block (RBBB) and ST depression (A) progressed rapidly to complete heart block and cardiac arrest (B). Autopsy showed lymphocytic infiltration in myocardium (C) comprised CD3+ T cells (D), many of which were CD8+ lymphocytes (E) and CD68+ macrophages (F) (adapted with permission from Johnson et al36).
