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 ...

Characterization of AF Recurrence and Substrate Health by Electrographic Flow (EGF) Consistency in EGF Mapping

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Electrographic flow (EGF) mapping is an FDA 510(k)‐cleared method for visualizing atrial activation wavefronts in atrial fibrillation (AF). Its clinical efficacy in detecting AF sources was demonstrated in the FLOW‐AF randomized controlled trial, and the underlying machine learning strategy used to develop and refine EGF source ...

Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Electrogram peak‐to‐peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography–derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained with omnipolar, bipolar, and unipolar mapping.

Development and Validation of a Novel Contact Force‐Integrated Pulsed Field Quantization Index for Pulmonary Vein Isolation in a Porcine Model

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
A two‐phase pre‐clinical porcine study was performed to develop and validate the Pulsed Field Quantisation Index (PFQI), the first bipolar‐specific ablation index integrating real‐time contact force (CF), pulse‐train number, delivery voltage, and impedance variation for bipolar pulsed field ablation (PFA).

Research Review: A scoping review exploring the needs, barriers, and facilitators to the collection of biological data in adolescence for mental health research

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background There is increasing recognition of the challenge of representativeness in data, including economic, social, and ethnic diversity, in biological mental health research. This is a particular challenge in adolescence, where brain and body development are impacted by the environment.

Pushing the limits of atomic force microscopy: Emerging methods for speed, resolution, and quantitative analysis

open access: yesJournal of Microscopy, EarlyView.
Abstract Since its introduction 40 years ago, atomic force microscopy (AFM) has transformed nanoscale imaging across the physical and life sciences. In biology, AFM has provided unprecedented insights into nanoscale biomolecular organisation under near‐physiological conditions, revealing structures and interactions inaccessible to many conventional ...
