The Relationship Between Spiral Waves and Fibrillation

The spiral waves form when cardiac cells get excited by the neighbors, but they have ion channels that are stretch activated. So if I touch a heart and I press on a heart, I can produce an activation. You could actually activate many, many, many cells in the heart that could actually could defibrillate. If he had to be just 20 milliseconds later, or not have gone into tribulation,. The student got hit hard enough to some of the cells get activated and he got hit exactly when his heart was finishing activating during the Twave. That then initiated the spiral waves which started fibrillation.
