When scheduling any dental or medical procedure not related to your pacemaker or implantable defibrillator, it is important to inform the dentists, doctors, and technicians that you have a heart device. They may need to consult with your cardiologist or electrophysiologist (EP) before performing the procedure. This is true especially if the procedure is a new or unusual one. Even though most dental and medical procedures are unlikely to affect the function of your heart device, some may require precautionary measures that prevent or minimize any effects.
