Key result
A modified Microlife blood pressure monitor detected atrial fibrillation with 97% sensitivity and 89% specificity using three sequential readings compared to EKG.
Why the study?
Does an automatic oscillometric sphygmomanometer accurately detect atrial fibrillation compared to EKG in unselected cardiology outpatients?
Population
405 unselected outpatients seen in two cardiology offices
Comparison
Automatic oscillometric sphygmomanometer… vs One electrocardiogram on each patient

Does an automatic oscillometric sphygmomanometer accurately detect atrial fibrillation compared to EKG in unselected cardiology outpatients?
Effect estimate: Sensitivity 97%, Specificity 89%
A modified automatic oscillometric sphygmomanometer demonstrates high sensitivity and specificity for detecting atrial fibrillation, suggesting potential utility for home monitoring to prevent stroke.
Wiesel et al. (2009) conducted a cross-sectional in Atrial fibrillation (n=405). Modified Microlife Blood Pressure Monitor vs. Electrocardiogram (EKG) was evaluated on Sensitivity and specificity for detecting atrial fibrillation (Sensitivity 97%, Specificity 89%). A modified Microlife blood pressure monitor detected atrial fibrillation with 97% sensitivity and 89% specificity using three sequential readings compared to EKG.
