An implantable medical device with a notification system. The device monitors itself and an implantee for one or more condition indicating notification and delivers the notification at a time the patient is determined to be wakeful and, optionally, at relative rest. The notification can be repeated periodically until acknowledged by the user or the system is evaluated and reprogrammed by the physician. A user input can be included to provide the device confirmation of receipt of the notification as well as to delay delivery of any indicated subsequent notifications. The notification is provided without requiring any additional or special dedicated hardware.

Implantable medical device with notification system

Various embodiments can permit electrode configurations that are used in implantable devices to be automatically changed. In some embodiments, configurations that are used to ascertain capture (ventricular and/or atrial) can be automatically changed by a stimulation device and then automatically configured for use. Various parameters associated with the electrical configurations can be automatically calibrated so that a stimulation device's automatic capture feature can continue to function notwithstanding the fact that an electrode configuration change has taken place.

Methods and systems for automatically switching electrode configurations

An implantable cardiac stimulation device and associated method capable of delivering non-invasive programmed stimulation for electrophysiological testing in which the onset of the non-invasive programmed stimulation is triggered by a cardiac event, either a detected intrinsic event or a stimulated event, occurring in the heart chamber to be tested. When a non-invasive programmed stimulation command is received by the implanted device, it switches to a routine that allows transition to a non-invasive programmed stimulation from a standard operating mode, during a refractory period. The stimulation device also provides a recovery delay following the last pulse of a non-invasive programmed stimulation sequence. If no intrinsic activity is detected during the recovery delay, a refractory period is started following the expiration of the recovery delay. During this refractory period, a transition from the non-invasive programmed stimulation state machine back to the standard stimulation state machine is accomplished.
