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

Intermittent left bundle branch block is uncommon. During anaesthesia,, left bundle branch block may be related to hypertension or tachycardia and its occurrence makes the diagnosis of acute myocardial ischaemia or infarction difficult. Patients with intermittent left bundle branch block often develop established left bundle branch block, which may represent an earlier state of ischaemic heart ...

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 (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...

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...
