Microlife AFIB Technology
Microlife AFIB is the world's only, medically proven technology for blood pressure devices that detects dangerous Atrial fibrillation (AFib). The high degree of accuracy has been proven several times in clinical trials and has been recommended by international specialists and physicians.
The majority of the available blood pressure devices allow blood pressure measurements to be applied simultaneously to irregular heartbeats and arrhythmias. However, this does not distinguish between the different types of arrhythmias.
Microlife blood pressure monitors with implemented AFIB Technology allow patients to be screened for Atrial fibrillation during blood pressure measurements at home. An algorithm calculates the irregularity index, which is the standard deviation divided by mean based on interval times between heartbeats. If AFib is detected during blood pressure measurements, the AFIB symbol is displayed. Microlife AFIB does not make a diagnosis, but provides important information for your doctor, who can refer you for a 12-lead ECG to confirm the presence of AFib.
A systematic review of all clinical evidence to the Microlife AFIB detector  showed that the highest sensitivity value (97%) is obtained when three sequential blood pressure measurements were performed with two or three AFib positive readings. The highest specificity value (89%) is obtained when with three sequential measurements, of which all three must be AFib positive. For this reason the Microlife blood pressure monitors with AFIB technology automatically measure three times.
The Microlife AFIB detection system has convincingly proven its accuracy, and showed that it leads to increased detection of new patients with AFib when used in general clinical practice. The National Institute for Health and Care Excellence (NICE) in United Kingdom officially recommends using Microlife WatchBP Home A during routine blood pressure measurement for all general practitioners in UK.
