1.The heart is independent of the brain because it has the SA node,that generates an electric current that transmits to the rest of the heart.
2.Although all of the heart's cells possess the ability to generate the electrical impulses that trigger cardiac contraction, the sinoatrial node is what normally initiates it.

I am going through the makers diet cleanse consisting of water,nits,seeds,fruits and veggies. Last night while sleeping I had full body shakes which apparently woke my husband . I awoke to incredibly fast heartbeat. Nothing else. What is my body deficient of? Btw. The cleanse has been going well until. The only change was that I ate a large amt of cheese in the afternoon. What does my body need to regulate again?
