Abstract

The authors evaluated the diagnostic accuracy of a new algorithm for detecting atrial fibrillation (AF) using a home blood pressure (BP) monitor. Three serial BP values were measured in 205 subjects with sinus rhythm and 75 subjects with AF confirmed by electrocardiogram. Irregular pulse peak (IPP) 15 was defined as follows: |interval of pulse peak - the average of the interval of the pulse peak| ≥ the average of the interval of the pulse peak × 15%. Irregular heartbeat (IHB) was defined as follows: beats of IPP ≥ total pulse × 20%. The sensitivities of IPP15 for diagnosing AF defined as two or three IHBs of three readings were 1.0 and 0.99, and the corresponding specificities were 0.97 and 0.99, respectively. The algorithm using two or more IHBs of three readings in the setting of IPP15 had the highest diagnostic accuracy for AF.

摘要

作者评估了一种使用家用血压(BP)监测仪检测心房颤动(AF)的新算法的诊断准确性。在 205 例窦性节律和 75 例经心电图证实的 AF 患者中测量了三个连续 BP 值。不规则脉搏峰(IPP)15 的定义如下:|脉搏峰间隔-脉搏峰间隔平均值|≥脉搏峰间隔平均值×15%。不规则心跳(IHB)的定义如下:IPP 的节拍数≥总节拍数×20%。将三个读数中的两个或三个 IHB 定义为 AF 的 IPP15 的灵敏度分别为 1.0 和 0.99,相应的特异性分别为 0.97 和 0.99。在 IPP15 的设置下,使用三个读数中的两个或更多 IHB 的算法对 AF 的诊断准确性最高。
