An Abnormal Electrocardiogram Following Pacemaker Implantation: Red Flag or Red Herring?
preprint
OA: closed
Abstract
An 88-year-old man underwent a dual chamber pacemaker implantation for complete heart block. Post procedure 12-lead electrocardiogram showed some abnormal findings. The reader is challenged to identify the abnormalities and then explain the mechanism of these findings. The discussion then guides the reader with the explanation.
