The impact of biological sex and stroke volume constituents on heterogeneity in the Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ relationship and skeletal muscle saturation during cycling

Experimental Physiology, EarlyView.
Abstract Interindividual variability in the cardiac output (Q̇$\dot{Q}$) to the rate of oxygen consumption (V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) slope (Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) in healthy males is related to stroke volume (SV); however, the impact of differences in left ventricular (LV) structure and function as well as ...

Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

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.

Presentation of preload and afterload to isolated heart preparations

The Journal of Physiology, EarlyView.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.
