Tacrolimus as a Possible Trigger of Tachycardias in a Heart-Transplanted Patient with Severe Diarrhea

Abstract

Tacrolimus is a broadly used immunosuppressive agent in organ transplanted patients. It is known that it may induce arrhythmias. We here report on a heart transplanted patient with supraventricular and ventricular arrhythmias with an elevated tacrolimus trough serum level due to severe diarrhea.
