This study checks how well Medtronic's heart devices work over time. These devices help keep the heart beating right. The study looks at devices like leads (wires), IPG (Implantable Pulse Generator), ICD (Implantable Cardioverter Defibrillator), and CRT (Cardiac Resynchronization Therapy) devices.

Eligibility: You can join if you recently got a Medtronic device or were part of a past study with Medtronic. You need to agree in writing for your health info to be used. You can't join if the device was implanted somewhere not in the study, or if the device's study group is full.

• The study looks at devices used for pacing, sensing, or defibrillation.
• Participants must agree to share health data.
• Some people might not be able to join due to laws or study limits.
