Continuous heart rate monitoring for automatic detection of atrial fibrillation with novel bio-sensing technology

Background.Heart rate monitoring is especially interesting in patients with atrial fibrillation (AF) and is routinely performed by ECG. A ballistocardiography (BCG) foil is an unobtrusive sensor for mechanical vibrations. We tested the correlation of heartbeat cycle length detection by a novel algorithm for a BCG foil to an ECG in AF and sinus rhythm (SR).Methods.In 22 patients we obtained BCG and synchronized ECG recordings before and after cardioversion and examined the correlation between heartbeat characteristics.Results.We analyzed a total of 4317 heartbeats during AF and 2445 during SR with a correlation between ECG and BCG during AF ofr=0.70(95% CI 0.68–0.71,P<0.0001) andr=0.75(95% CI 0.73–0.77,P<0.0001) during SR. By adding a quality index, artifacts could be reduced and the correlation increased for AF to 0.76 (95% CI 0.74–0.77,P<0.0001,n=3468) and for SR to 0.85 (95% CI 0.83–0.86,P<0.0001,n=2176).Conclusion.Heartbeat cycle length measurement by our novel algorithm for BCG foil is feasible during SR and AF, offering new possibilities of unobtrusive heart rate monitoring. This trial is registered with IRB registration number EK205/11. This trial is registered with clinical trials registration numberNCT01779674.

New Methods

Atrial fibrillation is known as the epidemic of the 21st century. This most common arrhythmia carries the risk of, inter alia, serious thromboembolic complications. Due to the paroxysmal nature of arrhythmia, the diagnosis of atrial fibrillation is not easy. New technologies and methods of minimally invasive, continuous ECG monitoring for early detection of arrhythmias are dynamically developing. The following article discusses new heart rate monitoring methods for the detection of atrial fibrillation.

Life Threatening

Aims: Assessing the effectiveness of novel bio-sensing technology (CardiacSense), for accuracy and reliability of automatic detection of life-threatening arrhythmias.Methods and Results: This prospective study consisted of Eighteen patients (13 males and 5 females, mean age 59.4 ± 21.3 years) undergoing induction of ventricular tachycardia/fibrillation or provocation of transient ventricular asystole. We tested the detection of provoked ventricular arrhythmias by a wrist-worn watch-like device which uses photoplethysmography (PPG) technology to detect the cardiac rhythm. We used simultaneous electrocardiographic (ECG) recordings as gold standard for arrhythmia definition and confirmation of beat-to-beat detection. A total of 1,527 QRS complexes were recorded simultaneously by ECG and PPG. The overall correlation between the ECG (R-R intervals) and the PPG (G-G intervals) was high, with a correlation coefficient of R = 0.949 (p < 0.001). The device accurately detected all events of mimicked life endangering arrhythmias, including five events of transient (adenosine-induced) ventricular asystole as well as seven episodes of monomorphic ventricular tachycardia and 6 events of ventricular fibrillation.Conclusion: This proof-of-concept study suggests that wearable devices using PPG technology, currently used to detect atrial fibrillation, may also have a role as automatic detectors of life-threatening arrhythmias.

Neonatal Heart Rate

BackgroundDetecting neonatal heart rate rapidly and accurately at birth is essential if resuscitation is required. The Neo-Sense prototype provides a quick, non-invasive method to measure neonatal heart rate at birth based on electric potential sensing technology. The study aimed to inform the prototype design process by exploring the required features and usability of this novel device among healthcare professionals.MethodsFace-to-face, semistructured interviews were conducted with healthcare professionals involved in the immediate care of babies at birth: paediatricians, midwives and neonatal nurses. Interviews were audio-recorded and subsequently transcribed verbatim. Two independent researchers coded and extracted the emerging categories and performed a thematic content analysis.ResultsIn total, 21 participants were interviewed, 7 from each professional group. Participants expressed a positive attitude towards the novel prototype. The three main themes extracted were anticipated limitations, advantages and suggestions for development and usage. Participants preferred a device that is easy to use and attach, one which is positioned in a mattress or pad, maintaining also the option of being mobile. Education was considered to have a key role in addressing staff anxiety. The ideal features most frequently mentioned were speed of assessment, reliability and accuracy.ConclusionsThe study enabled a better understanding of the perceived barriers and facilitators to developing a new heart rate monitoring device. The development of a quick and accurate device would have immense implications for clinical practice and the potential to improve neonatal mortality and morbidity.
