Fig. 1From: Assessment of left ventricular energy loss using vector flow mapping in patients with stages 1–3 chronic kidney diseaseTime-flow curve representing the division (five phases) of a cardiac cycle. IVR starts from the closure of the aortic valve to the opening of the mitral valve, ED starts from the opening of the mitral valve to the opening of the mitral valve once more, LD starts from the opening of the mitral valve once more to its closure, IVC starts from the closure of the mitral valve to the opening of the aortic valve, EJE starts from the opening of the aortic valve to the closure of the aortic valveBack to article page
