چکیده

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 disease. Cardiological investigation of our patient after operation did not point towards an organic cause of intermittent left bundle branch block.

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

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 descr...

Intermittent left bundle branch block in the athletic heart syndrome.

A 30-year-old man with typical findings of the athletic heart syndrome is presented because of the unique feature of intermittent left bundle branch block. Observations during right atrial pacing and exercise support the concept of autonomic control of intraventricular conduction, both adrenergic and cholinergic.

Intermittent left bundle branch block: anatomic substrate as reflected in the electrocardiogram during normal conduction.

Examination of ECGs in patients with intermittent left bundle branch block (LBBB) may provide insight into mechanisms and cause of LBBB. In this study, we obtained ECG files of patients with intermittent LBBB by mail solicitation of cardiologists. The group suitable for analysis included 275 patients in whom both LBBB was documented and at least one 12-lead ECG was available which demonstrated ...

Electrophysiological studies in patients with rate-related intermittent left bundle-branch block.

Two patients who developed left bundle-branch block with increase in heart rate are presented. Atrial pacing during His bundle recording studies showed differing responses in the ventricular specialized conduction system of the two patients. In one, the onset of left bundle-branch block was associated with no change in the previously normal HVinterval (so msec), while in the second the HV inter...
