Abstract

This document discusses, among other things, methods and systems for facilitating automated device programming at changeout. A method comprises receiving, from a first device, physiological data at a temporary storage device; and processing the received physiological data, wherein the processing includes determining if a first signal processing function was used by the first device and substantially offsetting the first signal processing function if the first signal processing function was used by the first device; and processing the resultant physiological data to be compatible with a second device. The method further comprising providing the processed resultant physiological data to the second device.

Claims

1. A system comprising:

an ambulatory medical device, comprising;

a communications port, adapted to receive reverted physiological data from an external processing device;

a memory, to store the received reverted physiological data; and

a processor, to process the received reverted physiological data by applying a third signal processing function to convert the received reverted physiological data to be compatible with a process executed on the ambulatory medical device,

wherein the reverted physiological data was produced by the external processing device by;

receiving physiological data from a first medical device, wherein the physiological data was obtained from raw data by the first medical device using a first signal processing function;

processing the received physiological data by applying a second signal processing function to the received physiological data, wherein the second signal processing function substantially reverses the first signal processing function to provide the reverted physiological data, and wherein the reverted physiological data is approximate to the raw data; and

transmitting the reverted physiological data to the ambulatory medical device using a modulation signal processing function; and

wherein the ambulatory medical device is further adapted to receive the reverted physiological data using a demodulation signal processing function.

3. The system of claim 1, wherein the communications port is adapted to be connected to an external programmer, and wherein the first medical device is an ambulatory medical device.

4. The system of claim 1, wherein the ambulatory medical device is an implantable medical device.

5. The system of claim 1, wherein the communications port includes a USB connector.

6. The system of claim 1, wherein the reverted physiological data includes electrocardiogram data.

7. The system of claim 1, wherein the reverted physiological data is associated with a tachyarrhythmia episode.

8. The system of claim 1, wherein the second signal processing function is calculated to minimize at least one of a mean squared error, a minimum phase shift, a minimum dominant frequency component deterioration, a reserved signal-to-noise ratio, or a high cross-correlation between sensed physiological data and the resultant physiological data.

9. The system of claim 1, wherein at least one of the first and second signal processing functions include at least one of a frequency-selective function, an upsampling function, a downsampling function, a re-sampling function, a filtering function, an amplifying function, an attenuating function, an averaging function, a function to calculate the median, mode, standard deviation or quartiles, a function to build a histogram, a function to estimate a probability distribution function or cumulative distribution function, or a compressing function.
