Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias. [PDF]

Ann Noninvasive Electrocardiol, 2023
Accurate automatic wide QRS complex tachycardia (WCT) differentiation may be accomplished through the use of novel parameters derived from computerized data of the (i) WCT electrocardiogram (ECG) alone and (ii) paired WCT and baseline ECGs. Once automated WCT differentiation models are integrated into commercially available computerized ECG ...

The mortality for the implantable cardiac defibrillator in nonischemic cardiomyopathy: An updated systematic review and meta‐analysis

Clinical Cardiology, Volume 45, Issue 12, Page 1163-1170, December 2022., 2022
Abstract The implantable cardiac defibrillator (ICD) is common for the management of nonischemic cardiomyopathy (NICM). Mortality is a crucial issue for patients with NICM. We can understand the mortality events of ICD versus medicine treatment via a systemic review and meta‐analysis of randomized clinical trials.

Parallel QR Factorization of Block Low-Rank Matrices [PDF]

, 2022
We present two new algorithms for Householder QR factorization of Block Low-Rank (BLR) matrices: one that performs block-column-wise QR, and another that is based on tiled QR. We show how the block-column-wise algorithm exploits BLR structure to achieve arithmetic complexity of $\mathcal{O}(mn)$, while the tiled BLR-QR exhibits $\mathcal{O}(mn^{1.5 ...

Design of a web laboratory interface for ECG signal analysis using MATLAB builder NE

Open Computer Science, 2022
An electrocardiogram (ECG) is a noninvasive test, determining any defect in the heart rate or rhythm or changes in the shape of the QRS complex is very significant to detect cardiac arrhythmia.

Accurate Fetal QRS-Complex Classification from Abdominal Electrocardiogram Using Deep Learning

International Journal of Computational Intelligence Systems, 2023
Fetal heart monitoring during pregnancy plays a critical role in diagnosing congenital heart disease (CHD). A noninvasive fetal electrocardiogram (fECG) provides additional clinical information for fetal heart monitoring.

Fast Time-Evolution of Matrix-Product States using the QR decomposition [PDF]

, 2022
We propose and benchmark a modified time evolution block decimation (TEBD) algorithm that uses a truncation scheme based on the QR decomposition instead of the singular value decomposition (SVD). The modification reduces the scaling with the dimension of the physical Hilbert space $d$ from $d^3$ down to $d^2$. Moreover, the QR decomposition has a lower

VLSI Implementation of QRS Complex Detector Based on Wavelet Decomposition

IEEE Access, 2022
This paper presents a very large–scale integration chip for a novel discrete wavelet transform (DWT) based QRS complex detection algorithm. In many aspects of electrocardiogram (ECG) analyses, QRS complex detection is the first step.

Effects of capillary number and flow rates on the hydrodynamics of droplet generation in T-junction microfluidic systems [PDF]

Journal of the Taiwan Institute of Chemical Engineers, Volume 129, December 2021, Pages 64-79, 2021
The hydrodynamics of droplets is significant in wide-ranging applications involving immiscible fluids and emulsions in food and pharmaceutical. The control and manipulation of droplets are primarily a function of flow governing and geometrical parameters.
