Mobitz II Second-Degree Heart Block During Total Hip Arthroplasty: ACase Report.

Spontaneous intraoperative development of Mobitz II second-degree atrioventricular block is a rare event which requires decisive action on the part of anesthesiologists and anesthetists. Given that this arrhythmia can be fatal if not properly managed, it is imperative that every practitioner know how it should be managed. Currently, there is a lack of literature discussing what to expect when a patient develops this complication and what the best management strategies are. This case report describes the unexpected development of Mobitz II second-degree atrioventricular block in an elderly patient with no prior history of conduction abnormalities undergoing total hip arthroplasty and how it was managed during the perioperative period to avoid morbidity or mortality. It includes a proposed management algorithm as an easy to use guide in the management of similar clinical scenarios. While this algorithm should be familiar to anesthesiologists and experienced anesthetists, it can serve as a reference in critical situations, and may help in educating trainees.
