Boston scientific received information that the patient implanted with this cardiac resynchronization therapy pacemaker (crt-p) experienced a syncopal episode.Review of stored device memory noted the only event stored was a right ventricular automatic threshold (rvat) test.The test was noted to be normal and back up pacing was noted to be provided with the test.Additionally, the test was noted to set to trend, so the test was only running for trend data and not to adjust the output.Manual threshold testing was then performed and was appropriate, however, the patient felt the test and was uncomfortable.It was undetermined if the syncope was related to the rvat.Rvat trend was then programmed off.No additional adverse patient effects were reported.This product remains implanted and in service.
