Implantable stimulation device and method for determining atrial autocapture using programmable PVARP

摘要: A pacemaker programmer and diagnostic system retrieves information stored within a analyzes the retrieved data in real time. The can be by means of telemetry communication link. automatically lengthens post-ventricular atrial refractory period (PVARP). determines capture generating stimulation pulses while maintaining ventricular pulse amplitude at level known to ensure capture, detecting loss capture. In response processor records threshold, restores PVARP their pre-test values. generator delivers backup concurrently with pulse, initiates premature contraction (PVC) reduce possibility retrograde P-wave initiating pacemaker-mediated tachycardia (PMT).
