“…However, we do not know the reproducibility of intermittent FF undersensing. Further, since the amplitude of the FF EGM may vary significantly with changes in posture, supine testing may not detect all patients at risk for FF undersensing . Additionally, it is unlikely that implant testing will detect the other unique failure modes we report.…”

“…Thus, to the extent that frequency content can be approximated by the ratio of amplitude to duration, NF EGMs should have higher frequency content than FF EGMs. This difference is accentuated during VT or VF during which slowed myocardial activation prolongs the FF EGM duration relative to its duration in sinus rhythm, while little change occurs in the duration of the NF EGM . Based on these considerations, it is likely that the optimal bandpass filter setting differs for FF compared to NF sensing.…”

“…In this case, none of the beats are faster than the detection interval of 320 ms so the counter will not increment and the episode is not detected. A detailed description of the AF SVT algorithm has previously been reported…”

“…The device senses these unexpected signals, referred to as oversensing, which can cause inappropriate pacing inhibition, pacemaker tracking or mode switching [11], [12]. For instance, an unintended mode switch is reported because of prolonged atrial activation [13].…”
