Reflex Syncope With Complete Heart Block Triggered by Swallowing in a Patient on Immune Checkpoint Inhibitor Therapy

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Immune checkpoint inhibitors (ICIs) are now standard of care for most advanced solid tumors. While effective, they are associated with immune‐related adverse events (irAEs), including rare autonomic complications. We present a patient with metastatic lung adenocarcinoma receiving nivolumab and ipilimumab who developed reflex syncope with ...

Sinus Bradycardia in Endurance Athletes From Physiological Adaptation to Potential Pathology

open access: yesQuality in Sport
Sinus bradycardia is a common electrocardiographic finding in trained athletes and a hallmark feature of the athlete’s heart. Reduced resting heart rate, particularly in endurance athletes, reflects physiological adaptation to long-term intensive ...

Brain strain: Blood flow and metabolism in environmental extremes

open access: yesExperimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Congenital sick sinus syndrome with breath holding and severe syncope episodes during infancy. A case report

open access: yesThe Turkish Journal of Pediatrics, 2000
Sick sinus syndrome is a rare cause of bradycardia in children without structural heart disease. A case of profound sinus bradycardia, sinus arrest with junctional escape, and pauses in a two-year-old infant with breath-holding and syncope ...

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

open access: yesThe 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.

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

open access: yesThe Journal of Physiology, Volume 604, Issue 13, Page 5458-5492, 1 July 2026.
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.

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.
