Complete left bundle branch blocks have focused our attention, primarily because they are a sign predictive of mortality and a predictor of coexisting cardiovascular disease. Left bundle branch block (LBBB) is usually permanent but may occur transiently or intermittently. Spontaneous remission of LBBB rarely occurs during anesthesia. We present two patients in whom chronic LBBB reverted to normal sinus rhythm shortly following denitrogenation with inhalation of 100% oxygen during induction of anesthesia.
Case Details
Disease Location
Heart
Personal Characteristics
A 78-kg, 81 years old retired fisherman suffering from cholelithiasis and cholecystitis. No history of cardiovascular disease, just hypertension.
Clinical Characteristics
Patient scheduled for laparoscopic cholecystectomy. Clbbb during operating room.
Remission Characteristics
While patient (2) was denitrogenized with oxygen, the clbb suddenly reverighted to normal sinus rhythm.
Treatment & Mechanisms
Proposed Remission Mechanisms
Oxygen supplement had quenched the increased myocardial oxygen demand state which the chronic lbbb preconditioned
Non-Clinical Treatment
Oxygen
