Design outcomes

Primary

Measure	Time frame
We use the Omron blood pressure monitor HME-907 and evaluate the performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) for detecting atrial fibrillation when irregular heartbeat is recorded at least once during three times of blood pressure measurements. We make the diagnosis of the atrial fibrillation based on the characteristic views (the uncertainty of the RR interval, disappearance of the P wave, appearance of the fibrillation wave) in the monitor electrocardiogram wave pattern.	—

Secondary

Measure	Time frame
We evaluate the performance for detecting atrial fibrillation by the following conditions. 1. Comparison by the number of measurement (once, twice, three times). 2. Comparison by the number of the irregular heart beat (once, twice, more than three times). 3. Comparison of the volume of the pulse pressure.	—
