The role of M cells and the long QT syndrome in cardiac arrhythmias: simulation studies of reentrant excitations using a detailed electrophysiological model

, 2004
In this numerical study, we investigate the role of intrinsic heterogeneities of cardiac tissue due to M cells in the generation and maintenance of reentrant excitations using the detailed Luo-Rudy dynamic model. This model has been extended to include a

Advances in Conductive Nanomaterials for Cardiac Arrhythmia and Future Directions in Bioevaluation Strategies

Advanced Healthcare Materials, EarlyView.
Conductive nanomaterials (CNMs) show promising potential in cardiac tissue regeneration and restoring cardiac rhythm as reported in several in vitro studies. This review article elaborates on the applications of CNMs in the treatment of myocardial infarction (MI) and MI‐induced cardiac arrhythmias, and it sheds light on the innovative approach of ...

Correction for Heart Rate Is Not Necessary for QT Dispersion in Individuals without Structural Heart Disease and Patients with Ventricular Tachycardia

Annals of Noninvasive Electrocardiology, 2001
Background: It remains controversial whether QT dispersion should be corrected for heart rate, especially when the limitations of rate correction formulae are considered.

Non‐PFAS‐Based Magnetic Polymer Sorbents for Efficient Removal of Perfluorinated Compounds from Landfill Leachate

Advanced Materials, EarlyView.
Magnetic polymer sorbents featuring non‐per‐ and polyfluoroalkyl substances (non‐PFAS)‐based fluorinated and cationic groups enable selective and efficient removal of multiple PFAS from complex landfill leachate. By optimizing functional group balance and polymer design, the sorbents achieve >90% removal, excellent reusability, and outperform ...

Effects of propranolol on the QT dispersion in congestive heart failure

Arquivos Brasileiros de Cardiologia, 1999
OBJECTIVE - Studies have shown that therapy with beta-blockers reduces mortality in patients with heart failure. However, there are no studies describing the effects of propranolol on the QT dispersion in this population.

The neutrino emission due to plasmon decay and neutrino luminosity of white dwarfs

, 2007
One of the effective mechanisms of neutrino energy losses in red giants, presupernovae and in the cores of white dwarfs is the emission of neutrino-antineutrino pairs in the process of plasmon decay. In this paper, we numerically calculate the emissivity
