Case 3

Abstract

A 51-year-old male with a history of pulmonary fibrosis and a single lung transplant is found to have atrial flutter on routine follow-up. Initially he is unaware of this rhythm, but later recalls an increase in fatigue over the previous week. He is referred for evaluation by an electrophysiologist. A Holter monitor shows his heart rate to be approximately 90 on average. He has periods of normal sinus rhythm and periods of atrial flutter. A 12-lead ECG during atrial flutter is shown in Fig. 3.1. © Springer-Verlag London Limited 2011.
