Remote monitoring of patients with implanted cardiac devices.

Three different types of implantable cardiac devices are now commonly used in clinical medicine: pacemakers (including cardiac resynchronization systems), cardiac defibrillators, and loop recorders. Although pacing specialists and electrophysiologists have traditionally been responsible for device follow-up, the newest generation of implanted devices stores a wealth of information that can be useful to the clinical cardiologist. Important information, in addition to device function, such as incidence and type of arrhythmias, general clinical condition of the patient, and hemodynamic status can now be stored on large databases that are available via web access to all physicians caring for an individual patient. The advent of the remote monitoring capability of implanted devices has initiated a rapidly accelerating paradigm shift in device follow-up that can potentially improve patient care at lower cost.
