I have wpw, i often have tachycardias i can control, i am having my heart slow down though, and can't control it. is there a way to?

Likely yes: As you probably know, WPW is a disorder of the electrical conduction system of the heart. I am assuming you have a cardiologist and he or she may have considered referring you to an electrophysiologist who may then consider ablation of the aberrant electrical pathway. He or she may also consider medical therapy with certain anti-arrhythmic drugs. You may wish to explore such options with your doc.
