Rate dependent left bundle branch block during general anaesthesia : Lesson for a novice anaesthetist

نویسنده

  • Manish Ruhela
چکیده

Rate dependent left bundle branch block (LBBB) occasionally occurs during anaesthesia when the heart rate exceeds a critical value. Transient LBBB has been associated with increased heart rate under general and local anesthesia and without obvious aetiologic factors during anaesthesia [1]. It is usually a benign disorder but it may mask the ECG manifestations of ischemia. This case report describes a case of rate dependent LBBB which occurred during general anaesthesia. Criteria for correct diagnosis of this benign entity of LBBB and methods for reversion to normal sinus rhythm for confirming the rate-dependent LBBB will be discussed in this article.

Intraoperative diagnosis of rate-dependent bundle branch block.

Rate-dependent left bundle branch block (LBBB) occasionally occurs during anaesthesia when the heart rate exceeds a critical value. While it is usually a benign disorder, it may mask the electrocardiographic manifestations of myocardial ischaemia and the ST-T wave pattern associated with LBBB may be mistaken for those of ischaemia. This case report presents two cases in which rate-dependent LBB...

Left Bundle Branch Block Under General Anaesthesia in an Athlete's Heart.

Left bundle branch block (LBBB) during anaesthesia is uncommon. During general anaesthesia, LBBB may be related to hypertension or tachycardia and its acute onset makes the diagnosis of acute myocardial ischemia or infarction difficult. We would like to present a case report of a healthy patient who developed LBBB intra operatively. Acute LBBB should lead to suspicion of acute coronary syndrome...

The Rate Dependent Bundle Branch Block

A chronic hypertensive patient with electrocardiogram (ECG) showing left bundle branch block (LBBB) was given general anesthesia for right modified radical mastectomy. Her ECG reverted to normal sinus rhythm intermittently during peri-operative period. This intermittent ratedependent LBBB is a rare entity. Though hypertension is one significant co-morbid condition, the risk evalution of LBBB du...
