Abstract: A method includes detecting, by an implantable medical device (IMD), attachment to the IMD of at least one implantable medical lead with at least one electrode; and triggering by the IMD, based on the detecting of the attachment to the IMD of the at least one medical lead, a device test sequence in which the IMD performs the following qualification tests over an evaluation period: detecting an impedance for at least one electrical path that includes the at least one electrode to determine a connection status of the IMD to the at least one electrode; and comparing EGM (electrogram) amplitudes of the patient over an EGM test period against a predetermined threshold.

Abstract: Ventricle-from-atrium (VfA) devices, systems, and methods may be configured to monitor a single channel of cardiac electrical activity and determine atrial events and ventricular events based on the single channel of cardiac electrical activity. Various processing, windowing, and thresholding may be used to identify atrial events and ventricular events within the single channel of cardiac electrical activity.
