Imaging With a Radio Tracer to Guide VT Ablations

Summary

Some patients are at risk for life-threatening fast heart rates. These can frequently be treated by using a catheter inside the heart to burn away the cells that create the fast heart rates. The purpose of this study is to image the nerves inside the heart of those patients. The investigators want to find out if abnormalities in the nervous system in the heart can help the physician to find the area that needs to be burnt away.
