Clinical Trial Summary

The study investigates the performance pf PulseOn Arrhythmia Monitor System that includes a wrist-worn device, which combines continuous optical heartbeat interval monitoring and intermittent ECG measurement, and a data management system used by healthcare professionals for data observation, in the detection of previously undiagnosed cardiac arrhythmias, especially atrial fibrillation.

Description:

The study consists of monitoring voluntary subjects with PulseOn Arrhythmia Monitoring System for the period of two weeks. The subjects are recruited mainly through newspaper advertisements. The study is executed in Tampere and Helsinki areas, Finland.

During the two week monitoring time, the subjects are instructed to wear the wrist device continuously, except when taking the device off e.g. for going to sauna or swimming, and for charging. The subjects are instructed to perform a 35-second ECG measurement (recording) in three cases:

1. Scheduled recording four times a day

2. In case of suspecting arrhythmic event, i.e. feeling symptoms

3. In case the wrist device instructs to perform a recording by vibrating and showing an LED light

The data collected in the study is analysed post-hoc. In the post-hoc analysis, the cardiac rhythm assessed automatically from the ECG measurements is visually confirmed by a cardiologist.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Diagnostic performance improvement with continuous optical measurement	Percentual improvement in the performance of detecting previously undiagnosed atrial fibrillation in the study population by the continuous PPG-based heartbeat interval monitoring when compared with relying only on scheduled and symptom -based ECG measurements. Cardiac rhythm assessed by a cardiologist from the ECG measurements that are made as a result of PPG-based arrhythmia notifications is compared with rhythm assessments made only from the scheduled and symptom-based ECG measurements. It is evaluated whether more subjects can be diagnosed having atrial fibrillation with the help of continuous PPG-based rhythm monitoring.	Duration of patient measurement, i.e. two weeks
Primary	Validation of the clinical performance of PulseOn Arrhythmia Monitor System in general population by showing the adequacy of the obtained ECG data for clinical decision making.	Data recorded by the study subjects during the two-week study time is assessed by a cardiologist and subjects are classified as having: "no observed arrhythmias", "atrial fibrillation episode(s)", "other potential arrhythmia", or "unconfident assessment" (due to the quality or lack of data). The percentage of "unconfident assessment" shall be less than 20% of the subjects.	Duration of patient measurement, i.e. two weeks
Primary	Validation of the clinical performance of PulseOn Arrhythmia Monitor System in general population by showing sufficient patient convenience for using the device for the intended duration of two weeks	The feedback from the subjects should show at least grade 3 in a scale of 1-5 for the "comfortability of using the wrist device".	Duration of patient measurement, i.e. two weeks
Secondary	Showing the benefit of the combined wrist-worn PPG and ECG solution in detecting other cardiac arrhythmias than atrial fibrillation.	The visual ECG-based rhythm annotation made by a cardiologist is compared with simultaneous PPG-algorithm alarm state. The incidence of notifications for other arrhythmias than atrial fibrilation is reported.	Duration of patient measurement, i.e. two weeks
Secondary	Evaluation of the necessity of performing scheduled ECG measurements in addition to ECG measurements triggered by PPG-based arrhythmia notifications for detecting atrial fibrillation.	Evaluation is done by comparing the atrial fibrillation detection outcome when considering only the PPG-triggered and symptom-based ECG measurements or when considering also the scheduled ECG measurements. The outcome parameter is the number of subjects that would have been left undetected if the scheduled ECG measurements were not taken.	Duration of patient measurement, i.e. two weeks
Secondary	Feedback about the usability of the evaluated solution from study subjects.	Feedback questions in scale of 1-5 and open-ended feedback. Easiness of use of the wrist device, understandability of the user interface, suitability of the user materials, and unobtrusiveness.	At the end of the 2-week measurement period
Secondary	Feedback about the usability of the evaluated solution from study personnel.	Feedback questions in scale of 1-5 and open-ended feedback. Easiness of use of the data management service, suitability of the user materials.	At the end of the study i.e. the end of 2022.
Secondary	Quality of the measured ECG signals	Percentage of the ECG measurements classified as inadequate quality for rhythm assessment either an ECG analysis algorithm or by a doctor.	Duration of patient measurement, i.e. two weeks
Secondary	Assessment of the subjects' adherence in using the solution.	Analysis of how well the participants will follow the study protocol and do the participants register their ECG in correlation with the wrist device notification. The outcome parameter is the percentage of scheduled and PPG-based notifications to take an ECG measurement and the variation of the percentage between the subjects.	Duration of patient measurement, i.e. two weeks
Secondary	Benefit of optical measurement for the speed of detecting atrial fibrillation	Comparison of the time to the first detection of atrial fibrillation or other arrhythmia when considering PPG-triggered ECG measurements or when considering the scheduled ECG measurements.	Duration of patient measurement, i.e. two weeks
Secondary	Evaluation of the accuracy of automatic ECG analysis algorithms when comparing with manual annotations by a cardiologist.	The automated assessment done for the 30-second ECG recordings is compared with the visual assessment to calculate the sensitivity and specificity for each rhythm category.	Duration of patient measurement, i.e. two weeks
