The heart is fundamental to our circulatory system. When it is healthy, it is roughly the size of a fist and sits in the middle of the chest, slightly to the left. Comprised of two interacting sides, separated by the septum, each are similar in having two compartments, the atria and ventricles. Blood enters the atria when they relax while the ventricles simultaneously contract and pump blood out into the aorta on the left side, or pulmonary artery on the right. When the ventricles relax, they fill while the atria assist this filling by contracting and moving blood into the ventricles. Valves between the atria and ventricles stop blood from flowing back in the wrong direction.

Alterations in cardiac mechanics following ultra-endurance exercise: Insights from left and right ventricular area-deformation loops Lord, Rachel; George, Keith; Somauroo, John; Stembridge, Mike; Jain, Nikhil; Hoffman, Martin; Shave, Rob; Haddad, Francois; Ashley, Euan; Jones, Helen; Oxborough, David (Elsevier, 2016)Background: The aim of this study was to use novel area-deformation (ε) loops to interrogate the interaction between the right ventricular (RV) and left ventricular (LV) mechanics following a 100-mile endurance run. Methods: ...
Does alcohol consumption affect the relationship between aerobic fitness and the systolic function of the heart? Roe, Lauren (Cardiff Metropolitan University, 2014)Aim: Exercise is known to affect both the morphological and functional properties of the heart. More aerobically trained individuals possess larger cardiac chamber dimensions and wall thicknesses than untrained individuals, ...
A depression in left ventricular diastolic filling following prolonged strenuous exercise is associated with changes in left atrial mechanics Oxborough, David; Whyte, Greg; Wilson, Matthew; O'Hanlon, Rory; Birch, Karen; Shave, Rob; Smith, Gillian; Godfrey, Richard; Prasad, Sanjay; George, Keith (Elsevier, 2010)Background Standard marathon running can result in a depression of left ventricular (LV) diastolic function during early recovery. Left atrial (LA) mechanics are integral in maintaining an early diastolic pressure ...
