About this study

Official title: Contactless Measurement of Heart Rate, Heart Rate Variability and Breathing Rate Using Face Video Analysis (Remote Photoplethysmography) - Validation of Shen.AI Vitals Software.

The purpose of this study it to evaluate the accuracy of heart rate, heart rate variability and breathing rate measurement with the use of Shen.AI Vitals software developed by MX Labs.

Read the detailed description

Resting heart rate (HR), heart rate variability (HRV) and breathing rate (BR) will be measured (estimated) with the use of remote photoplethysmography (1-minute face video analysis with Shen.AI Vitals software).

The measurements will be taken with various camera-equipped devices (smartphones, tablets, laptops) using either front camera (self-measurement) or rear camera (measurement made by someone else), in two different lighting conditions (artificial light or natural daylight), with various levels of device stability (fully stable or held in hand/s), and in two different body positions (sitting or supine). In total, each participant will have 8 measurements taken.

Standard deviation of normal heartbeat intervals (SDNN) will be used as the main HRV index.

Apart from the average HR (averaged over the whole 1-minute measurement), instantaneous values of HR (averaged over 10 s) will also be determined and displayed every 1 s by the Shen.AI VItals software.

In all cases, reference measurements will be taken simultaneously (chest ECG for the calculation of average and instantaneous HR as well as HRV; impedance pneumography for the determination of BR).

The reference measurements will be taken with Finapres Nova with the ECG+Resp module (Finapres Medical Systems B.V.).

For each measured parameter, the results from both methods will be compared using the Bland-Altman analysis or non-parametric limits of agreement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Accuracy of heart rate (HR) measurement with the software under test compared with the ECG-based measurement

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Accuracy of heart rate (HR) measurement with the software under test compared with the ECG-based measurement (time frame: day 1 (single visit, approximately 30 minutes)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Mar 2024.
