“…952,953 These types of continuous ECG monitoring devices have been
used in several studies to evaluate the results of surgical or catheter AF
ablation. 127,607,938,953,954,955,956,957,958,959,960,961 Although implantable subcutaneous monitors hold promise
for the determination of AF burden in the long term, AF detection algorithms are
primarily based on R-R interval regularity, and important limitations include
reduced specificity due to undersensing of beats, oversensing of myopotentials,
and irregular atrial and ventricular premature beats, as well as limited memory
resulting in electrograms not being retrievable to verify the correct rhythm
diagnosis. 941,944,962 Nevertheless, implantable continuous monitors can
ameliorate patient compliance issues and provide an assessment of long-term AF
burden and late recurrences, including asymptomatic episodes that might have
implications for continuation of anticoagulation.…”
