Electrical current firing in the heart can be picked up by EKG, but if there is no blood left in the tube you have no blood pressure.

Yeah, but the opposite. He has no heart but somehow has a pulse

PEA: pulseless electrical activity. But, when reading the article, it sounds like his body may have gone into hypovolemic shock. Long story short: When the body goes into systemic shock, it will vasoconstrict to pull all the blood to the vital organs, so your heart could still be beating but not have the pressure/volume to be able to detect a pulse.

If you cut out the heart it will beat for quite some time after death

I am doubtful of that but I haven't ripped enough hearts out of people to know for sure.

Wouldn't it run out of oxygen?

Heart can continue to beat but if there's nothing to pump through the blood vessels, you won't feel a pulse.

Mitchell McConnell hasn't looked like he had a pulse for the last 20 years. The man looked like he was made from off-brand play-doh

The quite some time seems hard to believe but the idea that heart transplants occur must mean that there must be some wiggle room I guess.

Depends on how neatly you cut it. If you just hack and slash, it doesn't last very long at all. But, as with everything, the more you practice, the better you ...

Oh, wait.

Uh, NVM.

Eventually, but it's a muscle. Salt applied to freshly butchered meat will spasm because it's still muscles with sugars left to burn.

Same thing like if someone gets decapitated. The heart might still pump for a while and shoot blood out everywhere. Doesn't mean the person of still alive.

Doesnt mean they're dead. Could still have brain function a minute or SO after decapitation.

If you culture cardiac muscle cells, they start beating.

Seconds, maybe. Once the brain loses blood pressure, most functions outside the stem go offline.
