Abstract
Systems, devices and methods for determining sensing quality changes and drops in an implantable medical device, remotely and/or within the device itself. A cardiac implantable medical device tracks, over time, a number of counters, the contents of which are communicated to a processor which may be part of a remote monitoring device or which may be a customer service center that receives data from remote monitoring devices and/or programmers. Counter data is analyzed to identify changes in sensing quality and/or to provide information useful for clinical investigations, system integrity checking, or device reprogramming.
Claims20
A method of monitoring operation of a cardiac implantable medical device (IMD), the method comprising:
- operating a communication circuit configured to communicate wirelessly with the IMD in a remote monitoring (RM) session that generates RM session data;
- analyzing the RM session data to determine sensing quality for the IMD, wherein:
- the RM session data includes data for a plurality of counters present in the IMD;
- and
- the step of analyzing the RM session data to determine sensing quality for the IMD is performed by:
- analyzing data in the plurality of counters;
- determining from the data in the plurality of counters that the IMD has experienced a drop in signal quality;
- and, if so,
- generating an alert indicating that the IMD has experienced a drop in signal quality.
A system for remotely monitoring a cardiac implantable medical device (IMD), the system comprising:
- a communication circuit configured to communicate wirelessly with a cardiac IMD in a remote monitoring (RM) session that generates RM session data;
- a processor configured to analyze RM session data to determine sensing quality for the IMD, wherein:
- the RM session data includes data for a plurality of counters present in the IMD;
- and
- the processor is configured to analyze RM session data to determine sensing quality for the IMD by:
- analyzing data in the plurality of counters;
- determining from the data in the plurality of counters that the IMD has experienced a drop in signal quality;
- and, if so,
- generating an alert indicating that the IMD has experienced a drop in signal quality.
A method of monitoring operation of a cardiac implantable medical device (IMD), the IMD maintaining a plurality of counters for events that the IMD identifies, the method comprising:
- analyzing data in the plurality of counters;
- determining from the data in the plurality of counters that the IMD has experienced a drop in signal quality;
- and, if so,
- generating an alert indicating that the IMD has experienced a drop in signal quality or modifying an operating parameter of the IMD.
