New Device Lets Man Live For Month Without A Heartbeat

HUFFINGTONPOST.COM - Craig Lewis had no pulse for a month before he passed away, but he was certainly still alive.

A new artificial heart, developed by Dr. Billy Cohn and Dr. Bud Frazier of the Texas Heart Institute, kept the 55-year-old cardiac amyloidosis patient alive without producing a pulse or showing a beep on an EKG machine, according to NPR. The continuous flow device, which is yet to have been specifically named, used a new system of screw-like rotor blades to push blood forward without pulsating.

As a result, Lewis had no pulse whatsoever. When his wife listened to his chest, all she heard was whirring.

It turns out, the body doesn't actually need a pulse, that's just how the heart works.

"The pulsatility of the flow is essential for the heart, because it can only get nourishment in between heartbeats," Cohn told NPR. "If you remove that from the system, none of the other organs seem to care much." >>>CLICK HERE TO READ MORE
