This is a prospective, non-randomized, multi-center, real-world post-market study to collect and evaluate data regarding the performance of the enhanced atrial fibrillation detection algorithm of the Assert-IQTM Implantable Cardiac Monitor (ICM) device.

Official Title

Assert-IQ Insertable Cardiac Monitor Post Market Study


The study's intent is to generate long-term real-world data on the safety, performance, and clinical benefits of the Assert-IQTM ICM device system. This clinical investigation is sponsored by Abbott Medical.


Atrial Fibrillation Paroxysmal, Atrial Fibrillation, Persistent, Cardiac Arrhythmia, Ablation, atrial fibrillation, Holter monitor, arrhythmia risk, syncope, shortness of breath, dizziness, palpitations, tachycardia, sinus pauses, Holter ECG recorder, Cardiac Arrhythmias, Holter monitoring in patients who have been successfully implanted with an Abbott Assert-IQ ICM device
