Abstract

A programmer and implantable stimulation device system with the implantable device and programmer in telemetric communication with each other wherein the implantable device internally monitors a plurality of physiological parameters and telemeters a plurality of those parameters to the programmer in at least a quasi-real-time manner such that the programmer can display waveforms corresponding to the internally monitored parameters in at least a quasi-real-time manner. The physiological parameters can include measurements of cardiac function, metabolic need, and patient orientation. In some aspects, the internally monitored parameters are provided continuously in a real-time manner and, in other aspects, the parameters are processed to a limited extent and provided as a derived parameter, such as an average, and/or as frames of data.
