Diagnostic accuracy of a novel cuffless self-blood pressure monitor for atrial fibrillation screening in the elderly.

Abstract

Blood pressure (BP) monitors equipped with atrial fibrillation (AF) detection algorithm are attractive screening tools for AF in elderly hypertensives. This study assessed the diagnostic accuracy of a novel cuffless pocket-size self-BP monitor (Freescan, Maisense) equipped with an AF detection algorithm, which displays results for the detection of "AF" or "Arrhythmia" during routine BP measurement. Subjects aged >65 years or 60-65 years with hypertension, diabetes, or cardiovascular disease were subjected to BP measurements using the Freescan device with simultaneous continuous Holter electrocardiography (ECG) monitoring. Readings with device notification "Instability" (29%) or "Error" (20%) were discarded. Data from 136 subjects with five valid Freescan BP measurements were analyzed (age 73.8 ± 7.1 years, males 63%, treated hypertensives 88%, AF in ECG 21%). Analysis of 680 Freescan readings vs ECG revealed specificity 99%, sensitivity 67%, and diagnostic accuracy 93% for AF diagnosis. When the "Arrhythmia" notification was considered as AF diagnosis, the sensitivity was improved (93%, 96%, and 93%, respectively). Analysis of AF diagnosis in subjects (diagnosis defined as at least three of five readings indicating "AF" or "Arrhythmia") revealed specificity, sensitivity, and diagnostic accuracy for AF detection at 94%, 100%, and 95%, respectively. These data suggest that the Freescan cuffless device could be used as a useful screening tool for AF detection during routine self-measurement of BP in the elderly.
