I just learned today that, in my case at least, my sinoatrial node, the area that normally generates electrical signals for the heart, is working fine. But there are other, "rogue" areas of the heart that are generating extra signals that are making the atrium go much too fast: fibrillation. That's why the ablation is really the right procedure, to stop the action of these rogue cells. Does that analysis seem to make sense?
