Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

The heart responds to pressure via the lung: Dive depth alters cardiac control in bottlenose dolphins

The Journal of Physiology, EarlyView.
Abstract figure legend Dive depth independently modulated cardiac regulation in bottlenose dolphins during controlled voluntary dives. Dolphins performed dives to 0.5, 5 and 10 m with standardized dive durations, allowing the effects of depth on cardiovascular responses to be evaluated.

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Slow calcium removal contributes to impaired lusitropic response to β‐adrenergic stimulation in HFpEF mice

The Journal of Physiology, EarlyView.
Abstract figure legend Heart failure with preserved ejection fraction (HFpEF) is the most common form of heart failure, yet major gaps remain in our understanding of its underlying mechanisms, disease progression and effective treatment strategies. Mice with HFpEF exhibited exercise intolerance and diastolic dysfunction in vivo, while isolated hearts ...
