Abstract:
1. An implantable device for recording physiological waveforms, the device comprising: electronic circuitry for sampling a physiological waveform of a patient; memory for storing physiological data; a processor under the control of executable instructions for processing samples of the physiological waveform, wherein the processor is programmed (i) to detect a predefined event in the physiological waveform by analyzing the physiological waveform against multiple parameters with each of the multiple parameters applied to a different segment of the physiological waveform and (ii) to store physiological data in the memory in response to detection of the predefined event, wherein the processor executes a diagnostic routine to identify locations in the memory that consume an amount of current above a threshold value during write memory transactions and the processor avoids storing the physiological data in the identified locations; and a wireless communication module for communicating with a device external to the patient after the implantable device has been implanted in the patient.
