[NR] Heart With No Beat Offers Hope Of New Lease On Life

The search for the perfect artificial heart seems never-ending. After decades of trial and error, surgeons remain stymied in their quest for a machine that does not wear out, break down or cause clots and infections.

But Dr. Billy Cohn and Dr. Bud Frazier at the Texas Heart Institute say they have developed a machine that could avoid all that with simple whirling rotors — which means people may soon get a heart that has no beat.

The doctors say the continuous-flow pump should last longer than other artificial hearts and cause fewer problems. That's because each side has just one moving part: the constantly whirling rotor.
It seems a bit eerie to not have a pulse in the traditional sense.
But I'm all for progress.

yikes what if the person with that heart faints? *checks pulse* There is no pulse... he is dead... The man stands up "ZombIESSSSSS"

I read the title and figured it was something like that. Gave me the chills. Very eerie sci-fi depiction came to mind.

I would HAVE to play dead every now and again, after a pulse check and a ten minute wait, OMG HE WALKS!!! He should have brain damage!!

Can't open the source atm, but this sounds VERY interesting

From heart failure

Now i want to see if this constant-blood-supply can help people like me who are prone to strokes

But when we run around and what not, our hear beats faster to supply more blood/oxygen around the body.

But this doesn't seem to speed up when youre doing any physical activity, you'd feel very fatigued very quickly.

But then again I guess if you get this done, you won't be in the right state to be doing physical activities anyway.

Correct.
This really isn't meant for athletes or anything like that.

Interesting.

I wonder if there's any anatomical reason that a beating pump would be better than a constant pump. The article says it doesn't matter but I wonder if any long-term studies will find something.
