Resolution of new left bundle branch block and ventricular tachycardia with immunosuppressive therapy in a patient with cardiac sarcoidosis

Abstract

About 5% of patients with sarcoidosis have symptomatic cardiac involvement while 20%–25% of the patients have cardiac involvement in the absence of symptoms.1, 2 These patients may present with conduction system abnormalities, ventricular arrhythmias, or heart failure symptoms. Patients with cardiac sarcoidosis (CS) are known to have a worse prognosis compared to those without cardiac involvement.3 We report a case of left bundle branch block and ventricular tachycardia (VT) in a patient with CS that resolved with immunosuppressive therapy.
