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.
How can you have a heartbeat but no pulse? Aren’t those the same thing? 🤨
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.
Wouldn’t it run out of oxygen?
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.
Seconds, maybe. Once the brain loses blood pressure, most functions outside the stem go offline.
Have you witnessed both these things?
Just the first one in person.
Yes.
Heart can continue to beat but if there’s nothing to pump through the blood vessels, you won’t feel a pulse.
Fuck….
If you cut out the heart it will beat for quite some time after death
“Things only my ex would know”
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.
If you culture cardiac muscle cells, they start beating.
I am doubtful of that but I haven’t ripped enough hearts out of people to know for sure.
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.

A turtle heart, same concept, nsfw
That implies you’ve done it at least once 🤔
When you heart stop beatin but she still suckin
Try blowing up a popped balloon and tell us how it goes.
So like Mitch McConnell?
Yeah, but the opposite. He has no heart but somehow has 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
