Self-monitoring home blood pressure (BP) devices are currently recommended for long-term follow-up of hypertension and its management. Some of these devices are integrated with algorithms aimed at detecting atrial fibrillation (AF), which is common essential hypertension. This study was designed to compare the diagnostic accuracy of two widely diffused home BP monitoring devices in detecting AF in an unselected population of outpatients referred to a hypertension clinic because of high BP.
In 503 consecutive patients the authors simultaneously compared the accuracy of the Microlife(®) BP A200 Plus (Microlife) and the OMRON(®) M6 (OMRON) home BP devices, in detecting AF.
Systolic and diastolic BP as well as heart rate (HR) values detected by the two devices were not significantly different. Pulse irregularity was detected in 124 and 112 patients with the OMRON M6 and Microlife BP A200 Plus devices, respectively. Simultaneous electrocardiogram (ECG) recording revealed that pulse irregularity was due to AF in 101 patients. Pulse irregularity detected by the OMRON M6 device corresponded to AF in 101, to supraventricular premature beats in 18, and to frequent premature ventricular beat in five patients, respectively. Pulse irregularity detected by the Microlife BP A200 Plus device corresponded to AF in 93, to supraventricular premature beats in 14, and to ventricular premature beats in five patients. The sensitivity for detecting AF was 100%, the specificity was 92%, and diagnostic accuracy 95% for the OMRON M6 and 100%, 92%, and 95 for the Microlife BP A200 Plus, respectively. AF was newly diagnosed by ECG recordings in 47 patients, and was detected in all patients by the OMRON device, and in 42 patients by the Microlife device.
These results indicate that OMRON M6 is more accurate than Microlife BP A200 Plus in detecting AF in patients with essential hypertension. Widespread use of these devices in hypertensive patients could be of clinical benefit for the early diagnosis and treatment of this arrhythmia and related consequences.
自我监测家庭血压（BP）设备目前被推荐用于高血压的长期随访和管理。其中一些设备集成了旨在检测心房颤动（AF）的算法，AF 是常见的原发性高血压。本研究旨在比较两种广泛传播的家庭 BP 监测设备在检测因高血压就诊于高血压诊所的未选择人群中的 AF 的诊断准确性。
在 503 例连续患者中，作者同时比较了 Microlife（®）BP A200 Plus（Microlife）和 OMRON（®）M6（OMRON）家庭 BP 设备检测 AF 的准确性。
两种设备检测到的收缩压、舒张压和心率（HR）值无显著差异。OMRON M6 和 Microlife BP A200 Plus 设备分别检测到 124 例和 112 例患者的脉搏不规则。同时进行心电图（ECG）记录显示，101 例患者的脉搏不规则是由 AF 引起的。OMRON M6 设备检测到的脉搏不规则分别对应 101 例 AF、18 例室上性早搏和 5 例频发室性早搏。Microlife BP A200 Plus 设备检测到的脉搏不规则分别对应 93 例 AF、14 例室上性早搏和 5 例室性早搏。OMRON M6 和 Microlife BP A200 Plus 检测 AF 的灵敏度分别为 100%、特异性分别为 92%和诊断准确性分别为 95%。新诊断为 AF 的心电图记录 47 例，OMRON 设备可检测到所有患者，Microlife 设备可检测到 42 例。
这些结果表明，在原发性高血压患者中，OMRON M6 比 Microlife BP A200 Plus 更能准确检测 AF。在高血压患者中广泛使用这些设备可能有助于早期诊断和治疗这种心律失常及其相关后果。
