The interplay between dynamic regulation of ion‐channel gating and trafficking in cardiac arrhythmogenesis

The Journal of Physiology, EarlyView.
Abstract figure legend Cardiac cellular electrophysiology is modulated by multiple factors, including temperature, extracellular K+, heart rate/pacing frequency, and drugs. These modulators can have distinct effects on ion‐channel gating and transcription/trafficking over time.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (
