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.

Contribution of the respiratory rhythm to sinus arrhythmia in normal unanesthetized subjects during positive-pres sure mechanical hyperventilation

, 2004
The precise contribution of the CO2-dependent respiratory rhythm to sinus arrhythmia in eupnea is unclear. The respiratory rhythm and sinus arrhythmia were measured in 12 normal, unanesthetized subjects in normocapnia and hypocapnia during mechanical ...

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.

Myasthenia Gravis and Thymoma

Muscle &Nerve, Volume 74, Issue 4, Page 1156-1173, October 2026.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.

Expiration-Triggered Sinus Arrhythmia Predicts Mortality Risk in the General Elderly Population

Journal of Cardiovascular Development and Disease
Reduced respiratory sinus arrhythmia, quantified as expiration-triggered sinus arrhythmia (ETA) from simultaneous electrocardiogram and respiration recordings, is a strong long-term mortality predictor in myocardial infarction survivors.

Inspiratory and expiratory sinus arrhythmia in healthy human

Physiological Reports
Breathing and ECG were recorded in 33 healthy human subjects at rest. The RR interval was labeled according to its occurrence in the respiratory phases: II (both R waves during inspiration), IE (first R wave in inspiration and following R wave in ...

Anaesthetic Techniques for Cardiac Ablation—A Scoping Review

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 9, October 2026.
ABSTRACT Background Cardiac arrhythmias, particularly atrial fibrillation, have rising prevalence and represent a growing global health burden. Catheter ablation is a commonly used treatment demanding sedation or anaesthesia for comfort, stability and safety. Anaesthetic techniques vary globally, and the optimal strategy has yet to be determined.
