Exercise renders a disproportionate load on the cardiac ventricles. Animal and human studies are concordant in demonstrating that right ventricle load (wall stress, work and oxygen demand), which is considerably less than for the left ventricle at rest, increases disproportionately during exercise. The result is that the right ventricle may be injured by prolonged intense exercise creating the potential for long term heart problems including serious arrhythmias.

This presentation describes possible mechanisms for arrhythmic heart remodelling by combining echocardiography and magnetic resonance imaging in real-time exercise studies. Repeatedly, the obtained results demonstrate that the focus of exercise changes in the heart should focus on the right ventricle and pulmonary circulation. The right ventricle’s unique shape, location and loading present specific issues for obtaining accurate measurements of function but modern imaging advances are rapidly overcoming these issues.
