 And let me just say again how lucky we in Prescott are to have this available to us. Yes, thank you. So what do I do? Or what does a cardiologist do? I do a little bit different because I can provide therapy for it that is the ablation. But there are drugs. Sometimes we try and give you drugs to see if we can keep you in normal rhythm while we're waiting to do the ablation. So what percentage of people can be controlled with medication?
