Figure 2From: Internal Flow Fraction discriminates patients with dyssynchronous heart failure from age and sex-matched controlsInternal flow is significanly increased thoughout the cardiac cycle in patients with dyssycnhronous heart failure compared to age and sex-matched healthy controls. Note the peaks in internal flow surrounding the periods of isovolumic contraction (time 0) and relaxation (vertical dashed line marking the end of systole).Back to article page
