We have accurately analyzed atrial fibrillation for 20 years. Our atrial fibrillation algorithm automatically quantifies atrial fibrillation episodes, giving your physicians hourly totals of QRS’ and minutes in atrial fibrillation and a calculation of the percent amount of time in Atrial Fibrillation. Our new Call Button feature is a fast way to deal with intermittent Atrial Fibrillation without changing Rules Sets.  We have two separate controls under Rules adjust the number of beats analyzed and the heart rate variability to help dial in and correctly call Atrial Fibrillation.
