Cardiac implanted devices provide not only therapy but also information on the clinical status of a patient. While beneficial, this increasing complexity also means that all clinicians must be knowledgeable about device function, indications for device use, and device follow-up. The second edition of Cardiac Pacing for the Clinician will provide a succinct, yet comprehensive reference for the implantation and follow-up of implantable cardiac rhythm devices. It is intended to be a practical guide for the day-to-day management of these increasingly complex devices, and is intended for all physicians caring for patients with cardiac implanted devices.
