Abstract
- Transient left bundle branch block (LBBB) is uncommon during anesthesia. It is mainly related to the changes in blood pressure or heart rate. Its occurrence can be confused with acute myocardial ischemia or ventricular tachycardia, therefore differential diagnosis is important. We report a case of transient LBBB which developed with hypoxia during monitored anesthesia care. LBBB is reversed to sinus rhythm after recovery from hypoxia.
