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).

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 (

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

Dyssynchrony without dysfunction: Left bundle branch block does not acutely reduce cardiac output

The Journal of Physiology, EarlyView.
Abstract figure legend Six electromechanical in silico heart models were simulated under healthy and pure acute left bundle branch block (LBBB) conditions. LBBB induced electrical dyssynchrony and increased left ventricular free wall strain, while the right and left ventricular ejection fraction remained relatively unchanged.

Characteristics and Outcomes After General Anaesthesia in Elderly Patients: A Nationwide Cohort Study

Acta Anaesthesiologica Scandinavica, Volume 71, Issue 1, January 2027.
ABSTRACT Background Elderly patients are more frail and have a higher burden of comorbidity, which could influence the risk of complications after anaesthesia. The aim of this study was to describe the elderly patient population undergoing general anaesthesia in Denmark.
