Arrhythmias and Conduction DisturbancesComparison of the Microlife Blood Pressure Monitor With the Omron Blood Pressure Monitor for Detecting Atrial Fibrillation
Section snippets
Methods
The study population included all patients aged ≥50 years in 2 outpatient cardiology clinics, who agreed to be enrolled in the trial. Patients with pacemakers or defibrillators were excluded from the study. The tested BPMs were the Omron M6 Comfort (HEM-7223-E; Omron Healthcare Co., Ltd., Kyoto, Japan) and the Microlife BP A 200 (Microlife Corp., Taipei, Taiwan).
A technician obtained a 12-lead electrocardiogram and then took the blood pressure and AF readings using both the Omron and Microlife
Results
There were 199 subjects enrolled in the study, of which 183 fulfilled all the inclusion criteria. The 16 subjects who did not meet the enrollment criteria were aged <50 years. AF readings for 99.5% of the subjects were recorded for both the Omron and Microlife devices. Demographic and medical history for the subjects who met the enrollment criteria are listed in Table 1. The age of the subjects is typical for those with AF. Subjects with a history of AF did not necessarily have AF on the
Discussion
The Omron M6 BPM with irregular heart beat detection had a very low sensitivity for detecting AF. The results for the Microlife monitor confirm the results of previous studies performed in medical clinics that demonstrated a sensitivity of 93% to 100% and a specificity of 86% to 93% for detecting AF.10, 11, 12 This high sensitivity makes the Microlife device a good choice for screening for AF in the clinic setting. Screening and early treatment of AF is likely to reduce the risk of stroke,
