Arrhythmias and conduction disturbancesScreening for Asymptomatic Atrial Fibrillation While Monitoring the Blood Pressure at Home: Trial of Regular Versus Irregular Pulse for Prevention of Stroke (TRIPPS 2.0)
Section snippets
Methods
The Microlife BP monitor (model BPM BP3MQ1-2D; Microlife USA, Inc., Dunedin, Florida) has an algorithm that detects AF by analyzing the standard deviation and mean of the pulse beat intervals.4 To determine the applicability of home monitoring for AF in a general medical population at risk for stroke because of AF, subjects were recruited from general internists' offices. Included patients met ≥1 of the following criteria: age ≥65 years, hypertension, diabetes mellitus, congestive heart
Results
A total of 160 subjects were enrolled in the trial. Ten subjects withdrew from the study before recording any electrocardiographic or AF-BP monitor readings. One subject did not record any electrocardiographic readings, and 1 subject with a pacemaker was erroneously enrolled in the trial. Nine subjects did not record logs of their AF-BP monitor readings. Data analysis was based on the remaining 139 subjects who had ≥1 AF-BP monitor reading documented with a comparative electrocardiographic
Discussion
Home BP monitoring with the Microlife BP monitor with a novel algorithm designed to detect AF was able to detect new AF in this trial. New AF was found in 2 subjects, 1 of whom was started on warfarin by her physician. The AF-BP monitor was found to have high sensitivity and specificity for diagnosing AF. In addition, the sensitivity and specificity for individual AF-BP monitor readings at home were comparable with the results obtained by the device when used in medical clinics. Although

2021, American Journal of MedicineCitation Excerpt :Implementing screening programs in primary care has been suggested.41 Numerous attempts have been made to discover optimal methods for detecting silent atrial fibrillation in the community;42 these screening techniques may be described as systematic (mass invitation sent to target population, eg, elderly individuals with risk factors)23,43-45 or opportunistic (testing in patients attending a physician visit for any reason).13,46-48 Additionally, in patients with symptoms consistent with paroxysmal atrial fibrillation, a clinically indicated search for atrial fibrillation may be advised using similar techniques and technologies.
Atrial fibrillation prevalence and risk profile from novel community-based screening in Thailand: A prospective multi-centre study
2021, IJC Heart and VasculatureCitation Excerpt :Lead-I ECG rhythm strip devices provide, on average, 93.9% sensitivity and 96.5% specificity [12], which is more accurate than pulse palpation. Automated oscillometric blood pressure (BP) monitors with AF detection algorithms also offer high sensitivity (97–100%) and specificity (89–93%) to detect AF [13–15], and are recommended by the UK National Institute for Health and Care Excellence (NICE) for screening patients ≥ 65 years during routine BP measurement in primary care [16]. Although these BP devices have been validated in many settings, the use and generalizability of these devices to detect AF in low-middle income countries remains unclear.

2019, Journal of ElectrocardiologyCitation Excerpt :However, it is ineffective compared to a continuous recording to detect short asymptomatic runs of AF. Automated BP machine with AF detection algorithm [19] have the same drawbacks given the paroxysmal nature of the arrhythmia and the short duration of the monitoring. One other wearable waterproof patch device has been evaluated with an excellent correlation with the Holter [20].
