The sinus node is a natural pacemaker that controls the rhythm of the heart. Electrical impulses travel from the natural pacemaker through the atria then pass through a filter before running down specialized fibers that activate the ventricles. The atria are above the ventricles‚ thus the term supraventricular. The term tachycardia
