Two doctors from the Texas Heart Institute successfully replaced a dying man’s heart with a device—proving that it is possible for your body to be kept alive without a heart, or a pulse.
The turbine-like device, that are simple whirling rotors, developed by the doctors does not beat like a heart, rather provides a ‘continuous flow’ like a garden hose.
If you listened with a stethoscope, you wouldn’t hear a heartbeat. If you examined [the] arteries, there’s no pulse. Hooked up to an EKG, [he'd] be flat-lined.”
