More Information
Summary:An implantable medical device configured to provide for an intracardiac function comprises a body, a sensor arrangement arranged on the body and configured to receive a cardiac sense signal, and a processing circuitry operatively connected to the sensor arrangement. The processing circuitry is configured to process the cardiac sense signal received using the sensor arrangement to detect a signal deflection in the cardiac sense signal potentially indicative of an atrial event caused by atrial activity, and to start a peak detection window based on the detection of said signal deflection for determining a peak amplitude associated with said atrial event. The peak detection window comprises one or more sub-windows, the processing circuitry being configured to determine a candidate peak value in each sub-window and to set the peak amplitude based on the valid candidate peak values of the one or more consecutive sub-windows.
