PATENTED AFIB TECHNOLOGY

Atrial fibrillation (AFIB) is one of the most common heart rhythm disorders. It is often asymptomatic and difficult to diagnose, but it is an important cause of stroke. 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.

HOW AFIB TECHNOLOGY WORKS?

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 [1] showed that the highest sensitivity value (98%) 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.

Focus on screening for atrial fibrillation

Accurately focus on screening for atrial fibrillation. Microlife's atrial fibrillation detection is clinically proven to be highly sensitive (98%) and highly specific (92%)

  • 臨床研究累計超過 10,000 名樣本，並發表於國際知名期刊。

    Clinical studies have accumulated more than 10,000 samples and have been published in internationally renowned journals.

  • 經臨床實證，在基礎醫療及居家量測血壓，同時偵測心房顫動，可作為 AF 初篩的可靠工具。

    Clinical evidence shows that measuring blood pressure in primary care and at home, while detecting atrial fibrillation, can be used as a reliable tool for primary screening of AF.

RECOMMENDED BY NICE (UK)

Professional recommendation from doctors: No. 1 Atrial Fibrillation Detection Technology

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. [2]

  • “The available evidence suggests that the device reliably detects atrial fibrillation and may increase the rate of detection when used in primary care.”
  • “WatchBP Home A should be considered for use in people with suspected hypertension and those being screened or monitored for hypertension, in primary care.”
  • Prevention of 2,000 strokes per year in the UK (81 per 100,000 patients screened aged 65 - 75 years and 182 per 100,000 patients aged 75 years and older).
  • Healthcare cost savings of € 31 million a year.

2013 Oxford Trail Oxford Clinical Trial

The famous Oxford University in the UK conducted a randomized clinical trial on 1,000 home medical patients in 2013. The results showed:

Ballroom Medical's AFIB is the best choice for the preliminary screening of atrial fibrillation. It measures blood pressure at the same time. The operation is simple and does not require professional explanation, and its accuracy is comparable to the single-lead ECG used in the clinic.

"So in primary care and home use, Microlife AFIB is more suitable as a screening tool for atrial fibrillation than ECG. These data suggest using atrial fibrillation technology for home blood pressure measurement, which has excellent diagnostic accuracy, so it can be used during initial diagnosis. It can be used as a reliable screening test." - Dr. George S. Stergiou (ESH member, famous European hypertension expert, has published 5 books & more than 150 related studies)
