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 ...

Generative MR Multitasking With Complex‐Harmonic Cardiac Encoding: Bridging the Gap Between Gated Imaging and Real‐Time Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2440-2450, November 2026.
ABSTRACT Purpose To develop a unified image reconstruction framework that bridges real‐time and gated cardiac MRI, including quantitative MRI. Methods We introduce generative multitasking, which learns subject‐ and dataset‐specific implicit neural temporal bases from sequence timings and an interpretable latent space for cardiac and respiratory motion.

Ephedrine for Reducing Onset Time of Rocuronium in Elderly Patients: A Randomised Study

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 10, November 2026.
ABSTRACT Introduction Onset time of rocuronium is prolonged in elderly patients compared to younger patients. Ephedrine reduces onset time of rocuronium in younger adults, but in elderly patients, the effect of ephedrine on onset time of rocuronium has not been investigated.

The “Spiked Helmet Sign” on Electrocardiogram Following Left Ventricular Assist Device Implantation: A Case Report

Annals of Noninvasive Electrocardiology, Volume 31, Issue 6, November 2026.
The Spiked Helmet Sign on electrocardiogram after LVAD implantation serves as a critical early warning of localized pericardial hematoma and impending tamponade. Prompt recognition should trigger immediate echocardiographic evaluation, as demonstrated in this case, to guide urgent management.
