Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Traumatic arteriovenous fistula after ice axe injury 27 years ago: A case report

Experimental Physiology, EarlyView.
Abstract We report a case of a traumatic arteriovenous fistula (AVF) between the superficial femoral artery and femoral vein that went undetected for 27 years following an ice axe injury during a climbing accident in 1997. An AVF is an abnormal connection between an artery and a vein, where blood flows directly from the high‐flow arterial system to the

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function

The Journal of Physiology, EarlyView.
Abstract figure legend Atrial fibrillation commonly develops in the left atrium and pulmonary veins (PVs), and can be triggered by sympathetic nerve activity. Here, we examined regional atrial differences in sympathetic nerve distribution and function in the rat.

Differential effects of central blood volume loading and unloading on pulmonary diffusing capacity in humans

The Journal of Physiology, EarlyView.
Abstract figure legend Central blood volume (CBV) is a key haemodynamic determinant of pulmonary diffusing capacity for carbon monoxide (DLCO) and its components, capillary blood volume (Vc) and membrane diffusing capacity (Dm,CO). However the contribution of CBV to DLCO regulation remains poorly defined. We investigated the effects of graded increases

CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.
