Equine vegetative endocarditis and vertebral osteomyelitis due to refractory Erysipelothrix rhusiopathiae infection

open access: yesEquine Veterinary Education, EarlyView.
Summary Erysipelothrix rhusiopathiae was the causative agent of vegetative endocarditis and vertebral osteomyelitis in a 24‐year‐old Irish draught gelding that presented with prolonged history of intermittent pyrexia and tachycardia. Clinical investigations revealed persistently reduced neck mobility, tachydysrhythmia and episodic pyrexia up to 41°C ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

open access: yesThe FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...

Multi-Class Arrhythmia Detection from PPG Signals Based on VGG-BiLSTM Hybrid Deep Learning Model

open access: yesBiosensors
Arrhythmia is a common and potentially life-threatening cardiovascular condition. Photoplethysmography (PPG) has emerged as a noninvasive alternative to electrocardiography for cardiac rhythm monitoring, yet most PPG-based methods remain limited to ...

First United States Experience With Focal Pulsed‐Field Ablation Using the FARAPOINT Catheter for Refractory Ventricular Tachycardia

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Drug‐refractory ventricular tachycardia (VT) after failed radiofrequency (RF) ablation remains a clinical challenge. Pulsed‐field ablation (PFA) is expanding to ventricular applications, but United States experience with focal pulsed‐field‐only catheters in VT is sparse, and pulsed‐field platforms are not equivalent across ...

Natural history of ventricular premature contractions in children with a structurally normal heart: does origin matter?

open access: yes, 2008
Aims Premature ventricular contractions (PVCs) are thought to be innocent in children with normal hearts, especially if they disappear during exercise.

Feasibility, Safety, and Efficacy of Pulsed Field Ablation for Ventricular Arrhythmias: Insights From a Large Health System Registry in the United States

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging non‐thermal ablation modality with proven safety in atrial arrhythmia ablation. However, data on its performance for ventricular arrhythmias (VA) remain limited. Objective To evaluate the feasibility, safety, and efficacy of PFA for complex VA in a multicenter real‐world US registry ...

Premature ventricular contractions in normal children.

open access: yesThe Turkish journal of pediatrics, 2008
Premature ventricular contractions (PVCs) are frequently seen in children with normal cardiac findings. The purpose of this study was to evaluate the characteristics and the prognosis of PVCs in children with normal heart. This study included 149 children with PVC who did not have systemic or cardiac disease. Their median age at diagnosis was 10 years (

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...
