Left Bundle Branch Pacing in Transthyretin Cardiac Amyloidosis and Alternating Bundle Branch Block

JACC: Case Reports, 2020
Progressive conduction system disease affects patients with transthyretin cardiac amyloidosis, often requiring permanent pacing as the His-Purkinje system is affected. We present a case of left bundle branch pacing in a patient with transthyretin cardiac

Multi and Independent Block Approach in Public Cluster [PDF]

arXiv, 2007
We present extended multi block approach in the LIPI Public Cluster. The multi block approach enables a cluster to be divided into several independent blocks which run jobs owned by different users simultaneously. Previously, we have maintained the blocks using single master node for all blocks due to efficiency and resource limitations.

The Functional and Imaging Implications of Left Bundle Branch Pacing in Ischemic Cardiomyopathy

Biomolecules
Heart failure with reduced ejection fraction due to ischemic cardiomyopathy remains a significant clinical challenge. Electrical conduction delays exacerbate symptoms by causing uncoordinated contractions, reducing pumping efficiency, and increasing ...

Alternating wide complex tachycardia after surgical aortic valve replacement

Indian Pacing and Electrophysiology Journal, 2021
A 51-year-old male developed recurrent episodes of palpitations and pre-syncope after surgical aortic valve replacement. Electrocardiograms after surgery revealed a wide complex tachycardia with alternating left bundle branch and right bundle branch ...

Separability Properties for a Class of Block Matrices [PDF]

arXiv, 2015
It is shown that, for the block matrices belonging to $M(nd,\mathbb{C})$ with commuting and normal block entries of dimension $d$, the separability of such a block matrices is equivalent to its semi-positive definity. The separability decomposition of lenght equal to the dimension of the block matrix (which is smaller then Carath\'eodory theorem ...

Block Sparse Bayesian Learning: A Diversified Scheme [PDF]

arXiv
This paper introduces a novel prior called Diversified Block Sparse Prior to characterize the widespread block sparsity phenomenon in real-world data. By allowing diversification on intra-block variance and inter-block correlation matrices, we effectively address the sensitivity issue of existing block sparse learning methods to pre-defined block ...

Bayesian Hypothesis Testing for Block Sparse Signal Recovery [PDF]

arXiv, 2015
This letter presents a novel Block Bayesian Hypothesis Testing Algorithm (Block-BHTA) for reconstructing block sparse signals with unknown block structures. The Block-BHTA comprises the detection and recovery of the supports, and the estimation of the amplitudes of the block sparse signal.
