Bundle-Branch Block [PDF]

Circulation, 1964
As part of an inclusive health examination of the population of Tecumseh, Michigan, electrocardiograms were recorded from 8,641 persons of all ages, 87.9 per cent of those living in the study area. Eighteen persons, twelve men and six women, had complete right bundle-branch block and a like number, composed of six men and 12 women, had left.

Constructing minimal blocking sets using field reduction [PDF]

J. Combin. Designs 24 (2015), 36-52, 2015
We present a construction for minimal blocking sets with respect to $(k-1)$-spaces in $\mathrm{PG}(n-1,q^t)$, the $(n-1)$-dimensional projective space over the finite field $\mathbb{F}_{q^t}$ of order $q^t$. The construction relies on the use of blocking cones in the {\em field reduced} representation of $\mathrm{PG}(n-1,q^t)$, extending the well-known

Episodic Left Bundle Branch Block—A Comprehensive Review of the Literature

Annals of Noninvasive Electrocardiology, 2016
Episodic (transient/ intermittent) left bundle branch block (LBBB) has been associated with different conditions such as bradycardia, tachycardia, anesthesia, acute pulmonary embolism, changes in intrathoracic pressure, chest trauma, cardiac ...

Vector electrocardiographic alterations after percutaneous septal ablation in obstructive hypertrophic cardiomyopathy: possible anatomic causes

Arquivos Brasileiros de Cardiologia, 2002
OBJECTIVE: Analyze the dromotropic disturbances (vector-electrocardiographic), and the possible anatomic causes, provoked by selective alcohol injection in the septal branch, for percutaneous treatment, of obstructive hypertrophic cardiomyopathy. METHODS:

Atrial Septal Defect Associated With Right Bundle Branch Block Masking Brugada Syndrome

JACC: Case Reports, 2023
A type 1 Brugada electrocardiogram pattern may be masked by typical right bundle branch block aspect. We present 2 cases (male patients, aged 18 and 22 years) of associated ostium secundum atrial septal defect with a right bundle branch block aspect and ...

The spectral laws of Hermitian block-matrices with large random blocks [PDF]

arXiv, 2007
We are going to study the limiting spectral measure of fixed dimensional Hermitian block-matrices with large dimensional Wigner blocks. We are going also to identify the limiting spectral measure when the Hermitian block-structure is Circulant. Using the limiting spectral measure of a Hermitian Circulant block-matrix we will show that the spectral ...

Core blocks of Ariki-Koike algebras II: the weight of a core block [PDF]

arXiv, 2007
We study combinatorial blocks of multipartitions, exploring further the notions of weight, hub and core block introduced by the author in earlier papers. We answer the question of which pairs (w,theta) occur as the weight and hub of a block, and we examine the action of the affine Weyl group on the set of blocks.
