Sex‐specific differences in mortality and neurocardiac interactions in the Kv1.1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP)

The Journal of Physiology, EarlyView.
Abstract figure legend The Kcna1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP) exhibits sex‐specific differences in SUDEP risk. Female mice exhibit a lower SUDEP risk than males, despite similar seizure characteristics and interictal cardiac function across sexes.

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.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

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 ...

Non‐invasive assessment of integrated cardiorespiratory network dynamics after physiological stress in humans

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to develop a non‐invasive method for visualizing the cardiorespiratory network under baseline conditions and following isolated or combined exposure to hypoxia, exercise, and sleep deprivation. Twenty‐two healthy participants underwent assessments at rest and after normobaric hypoxia (FIO2${{F}_{{\mathrm{I ...

Left Bundle Branch Area Pacing vs. Biventricular Pacing for Cardiac Resynchronization: Propensity Score Analysis

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
In this two‐center propensity score–weighted cohort of de novo CRT recipients, left bundle branch area pacing was associated with comparable resynchronization and clinical outcomes to biventricular pacing, with fewer late device‐related complications. ABSTRACT Background Left bundle branch area pacing (LBBAP) has emerged as a promising alternative to ...

An open‐label, single‐arm, dose‐escalating concentration–QT study to investigate the cardiac effects and safety of paroxetine in healthy adults

British Journal of Clinical Pharmacology, Volume 92, Issue 5, Page 1385-1396, May 2026.
Abstract Aims Paroxetine is a selective serotonin reuptake inhibitor (SSRI), approved for treatment of major depressive disorder and anxiety disorders. Some SSRIs are known to prolong the QT interval; however, clinical evidence to establish a lack of association between paroxetine and corrected QT interval (QTc) prolongation is limited. Therefore, this

Acute Music‐Frequency Exposure Modulates Salivary Stress and Neurotrophic Markers in Young Adults: A Randomized Controlled Trial

Brain and Behavior, Volume 16, Issue 5, May 2026.
Distinct music frequencies used are as follows: – 528 Hz → BDNF & CREB (learning, memory, and neuroplasticity). – 432 Hz → GRP78 (cellular stress response marker). – Stroop Test → No immediate cognitive difference. Note that a frequency of 528 Hz showed a pattern compatible with enhanced neurotrophic signaling, while a frequency of 432 Hz was linked to

Perforation of Jejunum as a Rare Complication of Pericardiocentesis: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT The safety of pericardiocentesis as a therapy for cardiac tamponade has improved since the advent of echocardiography‐guided pericardiocentesis. The most serious complications include injury of the cardiac chambers, laceration of the coronary arteries or intercostal vessels, puncture of the abdominal viscera or peritoneal cavity, pneumothorax,
