CRT and leadless (Micra) pacemaker implantation

CRT (Cardiac Resynchronization Therapy) is used for heart failure patients with conduction delays, aiming to improve heart pumping efficiency with three leads. Leadless pacemakers (like Micra) are implanted directly into the heart’s right ventricle, suitable for patients needing single-chamber pacing, often due to bradycardia or limited venous access.
