and stroke volume conditional on LV parameters.

Secondary variables were thoracic fluid index, ventricular ejection time, ejection fraction (EF), and end-diastolic volume
(EDV) as determined by TEB during EST.
For clinical purposes, left ventricular preload is usually defined in terms of left ventricular end-diastolic volume
In particular, the LV ejection fraction (LVEF) was calculated by dividing the difference between LV end-diastolic volume
and LV end-systolic volume by the LV end-diastolic volume
In the case group, the right ventricular (RV) end-diastolic volume
decreased from 81.
As the preload increases the left ventricular filling increases leading to increased LV end-diastolic volume
in order to maintain a high stroke work.
In patients with ToF, any increase in end-diastolic volume
can cause deterioration of right heart functions, which may even worsen during exercise (22, 23).
PRWS is the linear regression of the pressure volume (PV) loop area and end-diastolic volume
, measured during acute preload reduction.
All also had evidence of cardiac remodeling at baseline, defined as a left ventricular end-diastolic volume
index greater than 75 mL/[m.
LVEF, left ventricular ejection fraction; LVEDP, left ventricular end-diastolic pressure; LVEDVI, left ventricular end-diastolic volume
index; LVESVI, left ventricular end-systolic volume index; PAP mean, mean pulmonary arterial pressure; PAP diast.
Moreover, if diastolic function is truly normal, it must remain normal both at rest and during the stress of a variable heart rate, stroke volume, end-diastolic volume
, and blood pressure.
