A person can function normally if the blood through the vessels will go not with pushes, but with a continuous flow. This was proved by doctors of American Craig Lewis, who died of a heart disease - his life could not save even an electronic cardiac stimulator. As a result, the patient's heart was removed, but connected to a different type of device that helps blood circulate continuously throughout his body. Lewis lived for five weeks literally without a pulse, and his ECG had a straight line all that time. The cause of his death was liver failure due to amyloidosis, which was not associated with the implanted apparatus.
