Agreement of the performance of equine electrocardiogram recording devices for ECG complexity analysis

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Non‐linear equine electrocardiography (ECG) analysis is an actively developing study area which has the potential to lead to novel, artificial intelligence‐based diagnostic tools in equine cardiology. As more ECG recording devices are becoming available, there is a need to ensure results are interchangeable regardless of the ...

Automatic Mode Switching in Atrial Fibrillation [PDF]

open access: yes, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Imaging and physiology across the high–low cerebrospinal fluid pressure spectrum: Navigating diagnostic uncertainty in headache practice

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study was conducted to provide a clinically oriented, mechanism‐based framework for interpreting neuroimaging across disorders of cerebrospinal fluid (CSF) pressure, with particular emphasis on patients who fall between classic diagnostic categories of spontaneous intracranial hypotension (SIH) and idiopathic intracranial ...

Initial Pre‐Clinical Evaluation of the Augmented Ultra‐Low Temperature Cryoablation Catheter for Ventricular Ablations

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Ultra‐low Temperature Cryoablation (ULTC) using nitrogen cryogen near its boiling temperature of −196°C is a novel cardiac ablation modality capable of producing titratable lesions with depth exceeding 10 mm and has been recently introduced for catheter treatment of drug‐refractory ventricular tachycardia (VT). The ablative action

Sustained Idiopathic Outflow Tract Ventricular Tachycardia: Clinical Evidence for RVOT Predominance

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Idiopathic outflow tract premature ventricular contractions (PVCs) are most commonly localized in the right ventricular outflow tract (RVOT). The clinical significance of sustained outflow tract ventricular tachycardia (OT‐VT) regarding any predominance to one specific anatomic area remains uncertain.

Novel Observations on the Precursor Arrhythmias of Ventricular Fibrillation in the Ambulatory Setting

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Ventricular fibrillation (VF) is a lethal arrhythmia documented on outpatient telemetry monitoring. Ambulatory ECG in arrhythmic sudden death has shown VF as the terminal arrhythmia in about 80% of cases. Studies of VF in the ambulatory setting are sparse but suggest VF is commonly preceded by monomorphic ventricular tachycardia ...

The role of CaMKII-dependent augmented INa,L in arrhythmias during acute β-adrenergic stimulation [PDF]

open access: yes, 2018
The heart has evolved elaborate pathways for adapting function to acute stress stimuli [e.g. sympathetic stimulation of β-adrenergic receptors (β-ARs)].

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 ...
