Benign Left Bundle Branch Block
Annals of Internal Medicine, 1969Abstract Ten patients with left bundle branch block (LBBB) without signs or symptoms of underlying heart disease were carefully studied clinically and by cardiac catheterization including selective...

Left bundle branch pacing in alternating bundle branch block
Journal of Electrocardiology, 2023We present a case of symptomatic intermittent AV block showing during monitorization alternating bundle branch block. Presuming a high need of pacing, conduction system pacing was considered a more physiological alternative in this patient. Left bundle branch pacing restored a stable atrioventricular synchrony with a paced QRS complex similar to the ...

Left bundle branch block masquerading as right bundle branch block
American Heart Journal, 1954Abstract 1. 1. Four cases having electrocardiograms with the following features have been presented: (a) signs of left bundle branch block in the limb leads; (b) signs of right bundle branch block in the precordial leads; (c) qR deflections in aVR. 2. 2.

The vectorcardiogram in left bundle branch block
The American Journal of Cardiology, 1961Abstract Thirty vectorcardiograms of left bundle branch block were studied. The time, direction, sense and position of the Q, R and ST-T loops were studied. Twenty-five cases had QRS loops with greater duration than 120 milliseconds and five ranged from 100 to 120 milliseconds. The Q loop was present in six cases.

The Incomplete Left Bundle Branch Block
Diseases of the Chest, 1963SUMMARY The incomplete left bundle branch block is an electrocardiographic entity, having well defined criteria, yet is a frequent cause of misinterpretation. The R>L septal depolarization results in loss of the normal left ventricular q wave, being replaced by an initial r wave. On occasion, the initial r wave component may be fused on the ascending

Hypotension and Left Bundle Branch Block
The American Journal of Cardiology, 2017A 69-year-old man with chronic kidney disease and no chest pain had the new onset of hypotension. An electrocardiogram revealed left bundle branch block and inferior ST-segment elevation concordant with the QRS complexes in leads II and aVF, a pattern diagnostic of acute inferior myocardial infarction.

A 70-year-old woman was admitted to the intensive coronary care unit with suspected myocardial infarction. During the follow-up period, the patient twice developed left bundle branch block, which was shown to be related to high serum potassium levels secondary to hyporeninemic hypoaldosteronism and moderate renal failure.

Left bundle-branch block is ventricular excitation that is prolonged 0.12 second or more. It creates a specific pattern on vectorcardiogram and electrocardiogram, but changes in standardization are often needed to bring out detail.
