Left bundle branch pacing in heart failure patients with left bundle branch block: A systematic review and meta‐analysis

Pacing and clinical electrophysiology : PACE, 2021
The clinical benefit of cardiac resynchronization therapy (CRT) in heart failure patients with left bundle branch block (LBBB) has been demonstrated. However, a nonresponse rate of CRT nearly 1/3.

Left bundle branch pacing in alternating bundle branch block

Journal of Electrocardiology, 2023
We 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 ...

ECG patterns of successful permanent left bundle branch area pacing in bradycardia patients with typical bundle branch block

Pacing and clinical electrophysiology : PACE, 2020
To assess the electrocardiogram patterns of paced QRS narrowing after successful left bundle branch area pacing (LBBAP) and echocardiographic measurements in patients with bradycardia and bundle branch block (BBB).

Left bundle branch block masquerading as right bundle branch block

American Heart Journal, 1954
Abstract 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, 1961
Abstract 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, 1963
SUMMARY 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, 2017
A 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.
