About this study

Single-channel electrocardiograms (lead I of 12-lead surface ECG; 30 seconds) will be collected from subjects/patients at 11 clinical centers in Germany to train an Artificial Intelligence in the automatic diagnosis of regular and irregular heart rhythms. Heart rhythms of interest are normal sinus rhythm (SR), atrial fibrillation (AF), atrial premature beats (APBs), ventricular premature beats (VPBs), and nonsustained ventricular tachycardia (VT). Per diagnosis, 20,000 ECGs are required, for a total of 100,000 ECGs to be obtained from approximately 10,000 subjects/patients.

Read the detailed description

In phase 1 of a research project titled 'Prevention of stroke and sudden cardiac death by Recording of 1-Channel Electrocardiograms' (PRICE), a total of 100,000 30-sec single-channel ECGs (lead I of 12-lead surface ECG) will be collected from approximately 10,000 subjects/patients at 11 participating clinical centers in Germany. Relevant baseline clinical patient characteristics will also be recorded. The ECGs, diagnosed by an experienced electrophysiologist (diagnostic gold standard), will be fed into an Artificial Intelligence (AI) for the automatic detection of normal sinus rhythm (SR), atrial fibrillation (AF), atrial premature beats (APBs), ventricular premature beats (VPBs), and nonsustained ventricular tachycardia (VT). It is expected that the overall diagnostic accuracy of the AI against an experienced electrophysiologist will be on the order of 95%.

In PRICE phase 2, ECG diagnosis by the AI will be compared with the diagnosis by 3 general cardiologists of the same ECGs. It is expected that the AI will surpass the general cardiologists in terms of diagnostic accuracy.

The final clinical phase of the PRICE project will comprise a randomized controlled community trial of risk patients to establish the superiority in stroke prevention of AI detection of AF on smart-watch ECGs vs. no AF detection.

What is being measured

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

  1. Diagnostic accuracy of AI

    Overall diagnostic accuracy of the AI in the diagnosis of normal SR, AF, APBs, VPBs, and nonsustained VT (gold standard: diagnosis by experienced electrophysiologist)

    Measured: 1 year

  2. ECG R-R interval

    30-sec mean and standard deviation of R-R intervals

    Measured: Immediate

  3. ECG QRS-complex duration

    Measurement of width/duration of QRS complex; distinction between "narrow" (<=110ms) and "wide" (>110ms)

    Measured: Immediate

  4. ECG QRS-complex fragmentation

    Assessment of presence ("Yes") or absence ("No") of QRS-complex fragmentation

    Measured: Immediate

  5. ECG QTc interval

    Calculation of heart rate corrected QT interval (QTc) via Bazett formula from measured QT interval

    Measured: Immediate

  6. ECG T wave inversion

    Assessment of presence ("Yes") or absence ("No") of T wave inversion

    Measured: Immediate

Secondary outcomes (3)
  1. ECG P wave

    Assessment of presence ("Yes") or absence ("No") of P wave on ECG; measurement of P-wave duration (in ms)

    Measured: Immediate

  2. ECG PQ interval

    Measurement of PQ interval (onset of P wave to onset of Q wave) on ECG

    Measured: Immediate

  3. ECG QT interval

    Measurement of QT interval (onset of Q wave to end of T wave) on ECG

    Measured: Immediate

Questions about this trial

What is this clinical trial studying?

An observational study of Sinus Rhythm and Atrial Fibrillation, run by A-Rhythmik GmbH at 1 site in Germany.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 6 Apr 2022. 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 Germany. 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?

Results are not available in the source record.

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

Contact Karl-Heinz Kuck, MD (+49451 500 75301, karl-heinz.kuck@uksh.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diagnostic accuracy of AI (time frame: 1 year). The study lists 6 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 6 Apr 2022.
