Abstract
An implantable medical device for human implant. The device includes a telemetry transmitter and receiver for communicating information from the implanted device to an external programmer or monitor and for receiving commands or other information from an external programmer. The device is provided with one or more sensors and means for monitoring, recording and storing the recordings of physiologic signals after implant. The device is provided with a waveform compression and storage system which stores monitored signals in the form of defined analog voltages maintained within the device, rather than employing more traditional digital storage techniques.
