Abstract: 

A 39-year-old woman presented to a peripheral hospital with a 1-month history of fatigue, presyncope, exertional dyspnea, joint pain, and fever. Her medical history was significant for Child-Pugh A liver cirrhosis secondary to alcohol, gestational diabetes, hypertension, and mononucleosis one month ago. Her examination demonstrated a heart rate of 30 beats per minute but was otherwise unremarkable. Preliminary investigations in a peripheral hospital showed lymphopenia and 2:1 AVB. Further monitoring on telemetry showed alternating right bundle branch block and left bundle branch block, as well as intermittent complete heart block. The patient was transferred to a tertiary center, and a temporary transvenous pacing was placed owing to symptomatic heart block.
