1. A system for detecting a concurrent electrical therapy applied to a patient, comprising:
- an implantable medical device (IMD) configured to be implanted in the patient and configured to detect the concurrent electrical therapy, wherein the concurrent electrical therapy includes a plurality of electrical therapy pulses, wherein the IMD includes;
a storage, wherein the storage includes at least one characteristic of the therapy pulses in the concurrent electrical therapy;
concurrent therapy detection circuitry configured to detect electrical pulses and extract at least one characteristic of the detected electrical pulses; and
a controller configured to compare the at least one characteristic of the detected electrical pulses to the at least one stored characteristic of the therapy pulses and to declare that the concurrent therapy is being applied to the patient when the at least one characteristic of the detected electrical pulses favorably compares to the at least one stored characteristic of the therapy pulses.

Abstract
Various method embodiments detect a concurrent therapy, where the concurrent therapy includes a plurality of therapy pulses. Detecting the concurrent therapy includes detecting at least one electrical pulse, extracting at least one characteristic from the at least one electrical pulse, comparing the at least one characteristic of the detected pulse to at least one characteristic of therapy pulses, and detecting that the concurrent therapy is being applied if the at least one characteristic of the detected pulse favorably compares to the at least one characteristic of the therapy pulses.
