BHF | Ventricular fibrillation - cardiac arrest

A deadly spiral in the heart.

This image from Richard Clayton's research - which won the BHF's Reflections of Research science image competition in 2007 - shows a computer simulation of electrical activity in the heart during the onset of cardiac arrest.

Instead of regular activity controlled by the pacemaker of the heart, electrical activation (shown in red) has looped around into a spiral that will fragment, resulting in lethal electrical anarchy.

I am so impressed with Levodyn, it really made my blood pressure at normal level. it's really great.

I guess the Electrical impulses aren't going in a cycle, instead going everywhere else and the blood is basically stuck in the heart or the place its at and not being pumped around in the body

It was in the tags...I didn't check the tags *shrugs* Thanks for pointing it out though.

what do yo mean you would assume it to be V-Fib, it says in the video discription exactly what it is.

i dont understand it

[rimdup]

very interesting

This appears to be documenting electrical conduction through the heart. Starts out OK, then deteriorates into what I would assume to look like V-Fib.

Very interesting animation
