About this study

Official title: Validation of Signal Waveforms in a Consumer-based Wristwatch Prototype Device During Standard Cardiac Procedures

The iBeat Study is a single-center, prospective, unblinded validation of the photoplethysmography (PPG) and tissue oximetry (TO) signal waveforms recorded from a wrist-based sensor devices.

Read the detailed description

The goal of the proposed research is to validate PPG and TO signal waveforms recorded from a wist-based sensor device, which is worn on one or both arms, during catheter ablation, device interrogation, and defibrillation threshold testing (DFT). It is a non-invasive procedure that will include placing a wrist-based sensor on subjects who consent participate. Data collected from routine clinical care devices used during these procedures (catheter ablations, device interrogations, and DFTs) will confirm data collected from the iBeat wristwatch.

What is being measured

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

  1. Detect hemodynamic significant (e.g. Ventricular tachycardia, ventircular fibrillatio, supra ventricular tachycardia with fast ventricular rate, etc) arrhythmias using photoplethysmography

    Detect hemodynamic significant arrhythmia using changes in photoplethysmography [PPG] as measured using a wrist-watch.

    Measured: Immediate

  2. Detect hemodynamic significant (e.g. Ventricular tachycardia, ventircular fibrillatio, supra ventricular tachycardia with fast ventricular rate, etc) arrhythmias using tissue oxygenation

    Detect hemodynamic significant arrhythmia using changes in tissue oxygenation as measured using a wrist-watch.

    Measured: Immediate

Secondary outcomes (2)
  1. Detect benign arrhythmia (e.g. sinus tachycardia, atrial flutter, atrial fibrillation supra-ventricular tachycardia) using changes in photoplethysmography

    Detect hemodynamic significant arrhythmia by using changes in photoplethysmography signal, as measured using a wrist-watch.

    Measured: Immediate

  2. Detect benign arrhythmia (e.g. sinus tachycardia, atrial flutter, atrial fibrillation supra-ventricular tachycardia) using changes in tissue oxygenation

    Detect hemodynamic significant arrhythmia by using changes in tissue oxygenation signal, as measured using a wrist-watch.

    Measured: Immediate

Questions about this trial

What is this clinical trial studying?

An observational study of Arrythmia, Cardiac, run by University of California, San Francisco at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Detect hemodynamic significant (e.g. Ventricular tachycardia, ventircular fibrillatio, supra ventricular tachycardia with fast ventricular rate, etc) arrhythmias using photoplethysmography (time frame: Immediate). The study lists 2 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 5 Mar 2019.
