New Insights into Pacing Induced Cardiomyopathy

Reviews in Cardiovascular Medicine
Pacing induced cardiomyopathy (PICM) can occur as a complication due to pacing the right ventricle. Its precise definition varies across different studies, leading to uncertainty as to the best approach for managing this entity. More than 10% of patients

Design of a photochromic oscillator to be used as dynamical model of pacemaker neurons

, 2021
Neuromorphic engineering implements surrogates of neurons to develop Artificial Intelligence. A strategy to devise artificial neuron models is to use non-linear chemical systems that can mimic neural dynamics.

Channelrhodopsin ion selectivity determines mechanisms and efficacy of optogenetic defibrillation in human atria and ventricles

The Journal of Physiology, EarlyView.
Abstract figure legend A, we used in silico models of human cardiomyocytes and microelectrode recordings on transgenic zebrafish hearts to study electrophysiology during optogenetic perturbations. Specifically, we compared effects of three distinct classes of channelrhodopsins: the cation non‐selective Chlamydomonas reinhardtii channelrhodopsin‐2 (ChR2)

Cardiovascular Autonomic Neuropathy in Charcot–Marie–Tooth Disease: A Genotype‐Stratified Study of PMP22 Duplication and GJB1 Mutation Carriers

Journal of the Peripheral Nervous System, Volume 31, Issue 4, December 2026.
ABSTRACT Background and Aims Data on cardiovascular autonomic neuropathy (CAN) are sparse in Charcot–Marie–Tooth disease. We aimed to determine the prevalence of CAN in CMT1A and CMTX1 and its associations with neuropathy severity and heart rate variability (HRV), compared with age‐ and sex‐matched controls. Methods Thirty‐six CMT1A, 24 CMTX1 patients,

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Influence of Pacemaker Artifacts on Deep Neural Networks for ECG Classification

Current Directions in Biomedical Engineering
Patients with pacemakers represent a high-risk group for cardiovascular events. While deep learning has recently shown promising results in detecting many abnormalities in electrocardiograms (ECGs), little attention has been paid to its performance in ...

Diagnostic image quality of shoulder magnetic resonance imaging at 0.55T in healthy subjects and patients with rotator cuff injury: Prospective comparison with 1.5T

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Lower‑field 0.55 T MRI scanners with large‑bore design could offer patients more comfortable feeling and flexible position. With the advances in deep‑learning reconstruction and hardware optimization, 0.55T have greatly improved their image quality and cost‑effectiveness for musculoskeletal applications. However, its feasibility for
