What's the next step, a heart transplant? I'm not sure if this is considered a temporary solution or what.

Yes, it is temporary and he is likely on the transplant list. His aides are now busy running over motorcylists just to help out.

I guess he then gets a heart attack, wakes up from the pain and plugs it in before he croaks. Thing is I'm not sure you just die in your sleep peacefully if your heart stops?

A machine is not a heart. It isn't hooked up to the brain in anyway, and thus has no mechanism to say "Hey, your not getting blood." When the brain loses oxygen, you pass out. To lose enough oxygen to pass out takes about ten seconds (give it a try, exhale as much as possible and see how long you can go without breathing in).

With heart attacks, the heart starts beating irregularly, it doesn't stop completely.

From the History section in that article: "These devices are referred to as second generation VADs. A side effect is that the user will not have a pulse, or that the pulse intensity will be seriously reduced, and will need to carry documentation saying that the lack of a pulse does not mean that they are dead."

Do you have your papers sir? No?! ZOMBIE! Shoot him in the head!
 
I'm surprised the arteries have no problem with this. They evolved to handle a pulsed blood flow and now they have a constant flow. Though I guess the pressure would be lower for a constant flow than pulsed.
 
i guess the option of death or staying alive by machines where you still get to see the kids/family would make that decision.

btw..he is the fist zombie!
 
I saw this first on the Rachael Maddow show of all places, and for those of you wondering she kept politics out of it and even wished him well. When they mentioned he now had no pulse I thought it was the coolest thing ever. If I ended up like that I would prank the hell out of people.

I am talking about the medical concept here, all the predictable Cheney jokes can be made in P&N.

It's amazing to me that someone can have no pulse and yet with this assist device he can even expect to be able to ride a bike.

I'm sure this is impossible. A pulse is simply an artery in the body that can be palpated to feel the flow of the blood and heart's rhythms. If the device is doing the same job as the heart, then there should be a pulse.

Can you read?

A continuous flow of blood, therefore you'd feel no pulse.

I guess it doesnt surprise me about the no pulse considering our medical advances. I personally cant imagine what it would be like not having a pulse. Especially once I start working out. It would just feel weird not feeling my heart race.

Iirc, there is some evidence from cardiopulmonary bypass surgeries that the body does, in fact, prefer pulsatile blood flow.
