Design outcomes

Primary

MeasureTime frame
The presence / absence# of new onset of atrial fibrillation(recurrence of atrial fibrillation in the case of paroxysmal atrial fibrillation)detected at 12 months after ILR implantation# *Definition of atrial fibrillation detected with ILR:6 minutes and more persistent atrial fibrillation

Secondary

MeasureTime frame
1 30 seconds and more persistent supraventricular tachycardia(definition:heart rate over (220-age) beats/minute)*1 2 30 seconds and more persistent ventricular tachycardia(definition : heart rate over 150 beats/minute)*1 3 3 seconds and more R wave to R wave interval 4 bradycardia of 40 beats/minute and lesss heart rate 5 atrial fibrillation burden( atrial fibrillation duration/total observation time ) and number of occurrences during 1 year ILR monitoring in case of paroxysmal atrial fibrillation 6 all death*2, cardiovascular death*3, rehospitalization for heart failure , acute coronary syndrome, Stroke(ischemic or hemorrhagic stroke are no objects) 7 arrhythmia which has class 1 or 2 a indication(definition by 2018 Japanese Circulation Society/Japanese Heart Rhythm Society Guideline on Non-Pharmacotherapy of Cardiac Arrhythmias) for non-drug therapy such as cardiac implantable electrical devices and catheter ablation 8 Detection of atrial fibrillation by electrocardiogram (12-lead electrocardiogram / 3 minutes recording / 7 days Holter electrocardiogram*4) 9 Detection of arrhythmia (Supraventricular tachycardia, ventricular tachycardia, pause, bradycardia) by electrocardiogram (12-lead electrocardiogram / 3 minutes recording / 7 days Holter electrocardiogram*4) *1 Supraventricular tachycardia or Ventricular tachycardia directly confirmed by electrocardiographic waveform *2 Death from all causes *3 Sudden cardiac death, myocardial infarction, congestive heart failure, arrhythmia, death from stroke (ischemic or hemorrhagic are no object) *4 Use two evaluation points for all recorded hours and up to 24hours from the start of measurement. #For 1 to 4,8,9 measure the presence or absence, number of onset and the total detection time of arrhythmia. The total detection time in ILR is calculated based on total each event using the Carelink system.
