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 machine-assisted method comprising:

receiving, at a temporary storage device, physiological data from a first implantable medical device, wherein the physiological data includes electrocardiogram data obtained from raw electrocardiogram signals by the first implantable medical device using a first signal processing function;

applying a second signal processing function to the physiological data, wherein the second signal processing function substantially reverses the first signal processing function to provide reverted data, wherein the reverted data is conditioned to approximate the raw electrocardiogram signals;

communicating the reverted data to a second implantable medical device; and

applying, at the second implantable medical device, a third signal processing function to convert the reverted data to be compatible with the second implantable medical device.

2. The method of claim 1, wherein the electrocardiogram data is associated with a tachyarrhythmia episode.

3. The method of claim 1, wherein the second signal processing function is calculated to minimize one or more 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.

4. The method of claim 1, wherein one or more of the first and second signal processing functions include one or more 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.

5. The method of claim 1, wherein the applying the second signal processing function includes applying the second signal processing function in a time domain.

6. The method of claim 1, wherein the applying the second signal processing function includes applying the second signal processing function in a frequency domain.

7. The method of claim 1, wherein the third signal processing function includes one or more 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.

8. The method of claim 1, wherein the second signal processing function comprises a plurality of signal processing functions aggregated to substantially reverse the effects of the first signal processing function on the physiological data.

9. The method of claim 1, comprising:

receiving, at the temporary storage device, device settings associated with the first implantable medical device; and

configuring the device settings to be compatible with the second implantable medical device.

10. The method of claim 9, comprising providing the configured device settings to the second implantable medical device.

11. The method of claim 9, wherein the device settings include one or more of a tachy rate zone, a brady pacing mode, one or more thresholds of tachy discrimination algorithms, a tachy therapy parameter, a morphological template, a brady therapy parameter, one or more thresholds of heart failure decompensation detection algorithms, one or more thresholds of apnea detection algorithms, a patient name, a patient gender, a patient birth date, a patient height, a patient weight, a patient New York Heart Association class, a patient left ventricular ejection fraction, or a physician contact information.
