Introduction

Atrial Fibrillation (Afib) is a disorder found in 2.2. million Americans. During Afib the heart’s two small upper chambers (the atria) quiver instead of beating effectively. Blood isn’t pumped completely out of them, so it may pool and clot. If a piece of blood clot in the atria leaves the heart and becomes lodged in an artery in the brain, a stroke results. About 15% of strokes occur in patients with Afib.




Afib is often without symptoms and as a result many patients discover having Afib when they are in the emergency department of the hospital for having stroke, thus when it is too late. If Afib is detected in an early stadium treatment can be started which significantly reduces the chance of getting stroke.

Afib often is accompanied by hypertension and diabetes mellitus. Therefore, Microlife developed blood pressure monitors with an implemented Afib detector. This means that Afib can be diagnosed during blood pressure measurement without any extra efforts. With the implemented Afib detector Microlife follows the latest guidelines of the European Society of Hypertension (ESH) for home blood pressure monitoring. These guidelines indicate that the possibility to diagnose irregular heartbeats is a valuable addition to self-measurement devices [1].

Accuracy of the Afib detector

The accuracy of the Afib detection system has been investigated in two clinical studies [2, 3]. Both studies showed that the Afib detection system is very accurate.

Which devices have the AFIB detector?

Due to the enormous success and the high accuracy of the Afib detector Microlife has implemented this valuable tool in two devices for self-measurement of blood pressure: the WatchBP Home S (click on this link for more info) for early detection of Afib and controlling your blood pressure and the WatchBP Home A for follow-up during your treatment.

Conclusion

The AFIB detector that is implemented in the Microlife blood pressure monitors can diagnose whether you have Afib or not with a high level of accuracy, in an early stadium and without extra efforts.
