A journal article was reviewed that contained information regarding implantable cardiac monitors (icm).The article reports icms which misclassified atrial fibrillation (af) as atrial tachycardia (at).There were false positive af episodes which in some were due to external electric interference (noise), and t-wave oversensing (twos) and episodes with no stored data (electrograms) available.The status/ disposition of the devices is unknown.No patient complications have been reported as a result of this event.Further follow up did not yet yield any additional information.
