<p>A cardiac pacemaker device is in signal communication with a patient interface unit (PIU). The patient has the option of controlling various functions of the pacemaker via the PIU. In one embodiment, the pacemaker has an automatic means to detect a need for a change in pace rate, as well as initiate the calculated change. However, before or when initially increasing the pace rate the pacemaker device transmits an alert signal to the PIU. As the PIU alerts the patient that it believes they are engaging in exercise requiring a faster pacing rate, the patient can recognize a false signal and has the opportunity to transmit an override signal back to the pacemaker device (via the PIU), canceling the intended increase in pace. In other embodiments, the patient can use the PIU to notify the pacemaker that they are about to exercise, and optionally allow the pacemaker to work in automated mode or override the automated mode within reasonable limits to set a pacing rate commensurate with their physical activity.</p> |
