Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management
Advanced Science, EarlyView.Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

Animal Models and Experimental Medicine, EarlyView.Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss

Synchronization of the cardiac pacemaker model with delayed pulse-coupling [PDF]
arXiv, 2011 We consider the integrate-and-fire model of the cardiac pacemaker with delayed pulsatile coupling. Sufficient conditions of synchronization are obtained for identical and non-identical oscillators.

Multiple mechanisms of spiral wave breakup in a model of cardiac electrical activity [PDF]
, 2002 It has become widely accepted that the most dangerous cardiac arrhythmias are due to re- entrant waves, i.e., electrical wave(s) that re-circulate repeatedly throughout the tissue at a higher frequency than the waves produced by the heart's natural pacemaker (sinoatrial node). However, the complicated structure of cardiac tissue, as well as the complex

Deep Spatio-temporal Sparse Decomposition for Trend Prediction and Anomaly Detection in Cardiac Electrical Conduction [PDF]
arXiv, 2021 Electrical conduction among cardiac tissue is commonly modeled with partial differential equations, i.e., reaction-diffusion equation, where the reaction term describes cellular stimulation and diffusion term describes electrical propagation. Detecting and identifying of cardiac cells that produce abnormal electrical impulses in such nonlinear dynamic ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Genetically engineered cardiac pacemaker: stem cells transfected with HCN2 gene and myocytes - a model [PDF]
arXiv, 2005 Artificial biological pacemakers were developed and tested in canine ventricles. Next steps will require obtaining oscillations sensitive to external regulations, and robust with respect to long term drifts of expression levels of pacemaker currents and gap junctions. We introduce mathematical models intended to be used in parallel with the experiments.

ESC Heart Failure, EarlyView.Atrial fibrillation (AF) was observed in almost half of patients with insertable cardiac monitor and symptomatic heart failure (HF). One‐fourth of the patients had new onset AF and a higher rate of HF events compared with patients without AF. AF incidence was similar in HF patients with preserved versus reduced left ventricular ejection fraction ...
