AUTOCAPTURE AS A DIAGNOSTIC-TOOL - DETECT ION OF A LEAD DISLODGMENT

Autocapture is a newly developed automatic threshold tracking algorith m implemented in implantable pacemakers. Based on the detection of the cardiac evoked response, autocapture continuously controls the effect iveness of stimulation. Increases in threshold are immediately followe d by an adaption of the pulse amplitude. Automatic threshold tests per iodically lower the amplitude in order to adapt to decreased threshold s. Thus, changes in threshold can be monitored over a long period and utilized as a diagnostic tool. This case report demonstrates the diagn osis and monitoring of a microdislodgement by means of autocapture.
