New Sensors for Pacing and Diagnostic Application: What Is Their Clinical Uselfulness?
Modern cardiac pacemakers are capable of storing cardiac events on a long-term basis in their RAM. These data provide information on the pacemaker operation and on the patient’s health status and can be retrieved during the follow-up visits. The diagnosis of atrial arrhythmias has become a reality that is reliable and clinically relevant. In rate-responsive pacing, additional information can be retrieved from the retrospective examination of the sensor activity, which provides the physician with a display of the patient’s heart rate profiles during daily life. The diagnosis of chronotropic incompetence can be objectively validated, and the appropriateness of the sensor operation reliably verified. This may prompt reprogramming of the pacemaker to adjust the sensor-driven rates and better match the patient’s needs. However, no device currently available is able to provide enough information to assist in the diagnosis of comorbidity.
