Ventricles do ____ % of workload of the heart.
A
70%
B
30%
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A hyperdynamic left ventricle (ejection fraction ≥ 70%) seen on stress radionuclide myocardial perfusion imaging bears strong association with diastolic dysfunction and is therefore a marker of heart failure with preserved ejection fraction in appropriate clinical setting.

Detailed explanation-2: -A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection fraction is usually 40% or less.
