Abstract

We evaluated the diagnostic value of atrial fibrillation (AF) measured by a wrist-type pulse wave monitor in this case-control study. Six serial pulse wave values (three in the left and three in the right wrist) were measured using a wrist-type monitor in 29 AF patients and 30 subjects with sinus rhythm. We defined “monitor AF in irregular pulse peak (IPP) 15/20/25” as follows: (a) IPP: |interval of pulse peak − the average of the interval of the pulse peak| ≥ the average of the interval of the pulse peak × 15/20/25%; (b) irregular heartbeat (IHB): beats of IPP ≥ total pulse × 20%; and (c) monitor AF: ≥4 IHBs of the six pulse wave measurements. In IPP 15, the sensitivity and specificity were 0.97 and 1.00, respectively. Pulse wave analysis by a wrist-type monitor was shown to have high sensitivity and specificity for the diagnosis of AF.
