Blood Pressure Measurement - Microlife WatchBP O3 Instruction Manual

Special Function: atrial fibrillation (AFIB) screening
Screening for atrial fibrillation during blood pressure
measurement
The device is designed to screen atrial fibrillation during blood
pressure measurements in the «AMBULATORY» mode. This
device is able to detect atrial fibrillation with high accuracy: a
sensitivity of 97% and a specificity of 89%*. If atrial fibrillation is
detected this will be shown in the report.

AFIB Detector
The device can screen for atrial fibrillation during blood
pressure measurement.
Occasionally, the device might falsely detect atrial
fibrillation which can have two causes:
1) The arm has moved during blood pressure
measurement. For this reason it is of essential importance
to keep the arm still during the measurement.
2) Some arrhythmia (irregular heart beat) other than
atrial fibrillation might be present.
F
This device detects atrial fibrillation, a major cause of stroke. Not all risk
factors for stroke, including atrial flutter, may be detected by this device.
F
This device may not detect atrial fibrillation in people with pacemakers
or defibrillators.
