Chest pain and exercise induced left bundle branch block – A clinical dilemma

open access: yesJournal of Family Medicine and Primary Care, 2019
Exercise-induced left bundle branch block is a rare electrocardiographic phenomenon. We present two patients with angina pectoris who developed left bundle branch block on ECG during treadmill test. The first patient had non-obstructive coronary arteries

Current Opinions on New-Onset Left Bundle Branch Block after Transcatheter Aortic Valve Replacement and the Search for Physiological Pacing

open access: yesReviews in Cardiovascular Medicine, 2022
Transcatheter aortic valve replacement possesses a high validity for patients with aortic stenosis who are considered high risk for aortic valve replacement surgery, nowadays it is also considered for patients with intermediate risk or even lower risk in

Defining Left Bundle Branch Block Patterns in Cardiac Resynchronisation Therapy: A Return to His Bundle Recordings

open access: yesArrhythmia & Electrophysiology Review, 2019
Left bundle branch block (LBBB) is associated with improved outcome after cardiac resynchronisation therapy (CRT). One historical presumption of LBBB has been that the underlying pathophysiology involved diffuse disease throughout the distal conduction ...

Clinical implications of electrocardiographic bundle branch block in primary care

open access: yesHeart, 2019
Objectives Electrocardiographic bundle branch block (BBB) is common but the prognostic implications in primary care are unclear. We sought to investigate the relationship between electrocardiographic BBB subtypes and the risk of cardiovascular (CV ...

Peeling off the Mask: Pseudo Myocardial Infarction Pattern on Electrocardiogram During AICD Implantation

open access: yesIndian Pacing and Electrophysiology Journal, 2015
Lead induced transient right bundle branch block is not uncommon during pacemaker implantation. We describe a patient with old anterior wall myocardial infarction with severe left ventricular dysfunction presenting with recurrent ventricular tachycardia ...

Exercise-Induced Bundle Branch Block - an Infrequent Incidence

open access: yesNepalese Medical Journal, 2020
We describe an elderly woman who underwent a treadmill test preoperatively and was found to have Exercise-induced Left Bundle Branch Block without chest pain. Coronary angiogram was done which revealed a 70% stenosis in the fi rst diagonal branch of Left

A note on $2\times 2$ block-diagonal preconditioning [PDF]

open access: yesarXiv, 2020
For 2x2 block matrices, it is well-known that block-triangular or block-LDU preconditioners with an exact Schur complement (inverse) converge in at most two iterations for fixed-point or minimal-residual methods. Similarly, for saddle-point matrices with a zero (2,2)-block, block-diagonal preconditioners converge in at most three iterations for minimal-

Total Masquerading Bundle Branch Block [PDF]

open access: yesAnnals of Noninvasive Electrocardiology, 2015
We report a case of 82-year-old female with total masquerading bundle branch block. We discuss the problems with ECG analysis.

Expanding benefits from cardiac resynchronization therapy to exercise‐induced left bundle branch block in advanced heart failure

open access: yesESC Heart Failure, 2020
Indications of cardiac resynchronization therapy (CRT) do not include exercise‐induced left bundle branch block, but functional impairment could be improved with CRT in such cases.
