Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Background Catheter ablation is an established therapy for atrial fibrillation (AF), with thermal ablation as a standard modality. Pulsed‐field ablation (PFA) is a nonthermal alternative that selectively ablates myocardium while sparing collateral tissue. Its comparative autonomic impact relative to thermal ablation remains unclear.

Experimental Physiology, EarlyView.Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Zdravniški Vestnik, 2013 Background: Head-up tilt (HUT) test is an important tool in establishing the cause of past syncope. As postural tachycardia is associated with orthostatic intolerance, we hypothesise that heart rate (HR) increase during the early phase of HUT can be used

Frontiers in Pediatrics, 2018 Introduction: Orthostatic intolerance is common among individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). In some ME/CFS case definitions, orthostatic intolerance is considered a core feature of the disorder.

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Experimental Physiology, EarlyView.Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

A numerical model to assess deconditioning of the cardiovascular system in long-term exposure to microgravity. Verification and simulation of Mars mission scenarios [PDF]
, 2016 Numerical simulations of the cardiovascular system are particularly important in scenarios where it is difficult to experiment different weightlessness exposure conditions.

Autonomic symptoms in hypertensive patients with post-acute minor ischemic stroke [PDF]
, 2015 Background Most studies regarding autonomic dysfunction in ischemic stroke are limited to heart rate and blood pressure changes during the acute phase. However, there are few data on quantitative assessment of autonomic symptoms.

Experimental Physiology, EarlyView.Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.
