Okay, I will be sure to reach out to my medical school and let them know that modern medicine completely misunderstands the function of cardiac pacemaker cells and the sinoatrial node. They should also check on all the people walking with dysautonomia. I'm sure they will be surprised that their hearts actually haven't been beating this whole time.

what do you think controls the AV node, the SA node, and the Bundle of hiss?? the heart controls itself, or its impulses come from the ANS, which is a sub branch of the CNS, which is the brain and the spinal cord.

Are you suggesting something afib is actually neurological in origin?

Call JAMA, The Lancet, NEJM! They have to know!

Wait you googled SA node and you still think you're not wrong?

Damn, dude.

The brain controls the SA node, but the SA node can function without the brain. There's also a ventricular pacemaker. There's backups to the backups. The heart is an important organ.
