[|AI|]  Hidear205 ejection fraction means critically dangerous ejection fraction. Ejection fraction of a normal person is 60%, this means that if 100ml blood comes to the body, 60% will be supplied to the body. Less than 30% e.f signifies critically dangerous ejection fraction. Sory but EF can Chat Doctor. LEAD left ventricular assisted device is transition zone between cardiac transplant and heart decoration, he could be given Alva for 3 years, during this time you make sure to get a brain-dead donor of heart. Good luck at an EF of 20% patient can have any life threatening arrhythmia, which can lead to cardiac arrest, 5 year survival rate is less than 20% without acid or lead
