Re: Heart of Traffic Victim Lays on the Asphalt Still Beating
No, but in 600 years it will no doubt possible. Don't know if someone already explained this (and I won't read all 6 pages), so here it goes: the heart is controlled by it's own pacemaker called the atrioventricular node (AV node), which is independent (but can be affected by) the central nervous system. So even if you cut all nerves innervating the heart, it will still beat. Now, to beat it requires electrical activity which is produced by differences in ion inflow and outflow. This heart probably had still enough ion gradients to produce depolarizations (changes in membrane potential) that fired each beat. |

Re: Heart of Traffic Victim Lays on the Asphalt Still Beating
I just think it's crazy that the heart was ejected from the body intact enough to still throb and "beat". Seems like if it was hit hard enough to get ripped from your chest, it'd be dead. haha.

Re: Heart of Traffic Victim Lays on the Asphalt Still Beating
I've seen lots of hearts beating outside the body before. In real life and on tv/film/docus and so on... Not sure about the physics behind it, at least not to the extent to start explaining it. But if you're a hunter and just shot a deer, for example, and after you've engutted the deer, you may stand there with an animal's beating heart in your hand. As it with fish. I've engutted thousands of little and big fishies and have held their beating hearts in my hand. You just have to do it within a certain amount of time and the heart must not have caused death or in any other way or fashion be damaged. Other than that, I'll keep my big mouth shut! But in this fellow's case, I hope the paramedics came quickly! All they had to do was to rinse it and find someone in their papers waiting for a heart on "the fly"...       Let's go hunting, Hunter!  |

Re: Heart of Traffic Victim Lays on the Asphalt Still Beating
omg!!! that was amazing... it´s only electrical impulse, that heart doesn`t know that his body is dead..
