NCT05890716

Brief Summary

WILLEM is a multi-center, prospective and retrospective cohort study. The study will assess the performance of a cloud-based and AI-powered ECG analysis platform, named Willem™, developed to detect arrhythmias and other abnormal cardiac patterns. The main questions it aims to answer are:

  1. 1.A new AI-powered ECG analysis platform can automatice the classification and prediction of cardiac arrhythmic episodes at a cardiologist level.
  2. 2.This AI-powered ECG analysis can delay or even avoid harmful therapies and severe cardiac adverse events such as sudden death.

Outcome Measures

Primary Outcomes (1)

  • Detection of cardiac arrhythmias and cardiac patterns in the electrocardiographic signals

    Willem™ heart rhythm and cardiac pattern performance compared to standard manually performed cardiologist diagnosis.

    real time to 7 minutes

Secondary Outcomes (4)

  • Survival at follow-up

    1 year after the first ECG (prospective patients) or after patient enrollment (retrospective patients)

  • Major Adverse Cardiovascular and Cerebrovascular Events (MACCE)

    1 year after the first ECG (prospective patients) or after patient enrollment (retrospective patients)

  • Re-hospitalization

    1 year after the first ECG (prospective patients) or after patient enrollment (retrospective patients)

  • Change in quality of life

    1 year after the first ECG (prospective patients) or after patient enrollment (retrospective patients)

Study Arms (2)

Train group

Consecutive patients admitted to the hospital due to cardiac disorders (retrospective and prospective) with at least one relevant ECG record \>10 sec in raw data will be used to design new methodologies and algorithms for cardiac patterns recognition.

Diagnostic Test: AI-powered ECG analysis to detect cardiac arrhythmic episodes

Test group

Consecutive patients admitted to the hospital due to cardiac disorders (retrospective and prospective) with at least one relevant ECG record \>10 sec in raw data will be used to evaluate performance of methodologies aiming to avoid overfitting. Every 10 patients included in Train group; a new patient is included in the test group.

Study Population

Patients recorded with a mid to long-term ECG device according to guidelines. ECG data (ECG must have been recorded according to the technical standards for the safety and essential performance of medical electrical equipment defined in EN 60601-2-47:2015.): 12-lead ECGs including rest electrocardiograms, stress ECG Test (exercise Electrocardiogram or treadmill test), Holter devices, long-duration Holter devices, event recorders, insertable cardiac monitors, 6,3,2,1-lead ECG wearables, textile electrodes and patches, smartwatches, cardiac monitors, cardiac telemetries, hemodynamic and electrophysiology recording system (i.e., polygraphs), automatic external defibrillator (AED), semi-automatic defibrillator (DESA), home telemonitoring systems and other similar devices.

You may qualify if:

  • Patient presenting relevant cardiac arrhythmias and cardiac patterns (including supraventricular tachycardias, abnormal ECG patterns, ventricular tachycardias, ventricular fibrillation, pulseless electrical activity or asystole among others) that have been recorded with at least one short-term ECG medical device according to guidelines with ≥1 signal-channel.
  • Patient with suspected or diagnosed acute/chronic cardiac diseases (including patients with heart failure, patients with history of cardiac arrhythmias, patients with probable coronary artery diseases, patients with cardiomyopathies, patients with pacemakers or implantable cardioverter-defibrillators (ICD), patients with indication of pacemaker or ICD in current or short-term phase, patients participating in other interventional clinical investigation, patients with hemodynamic instability or acute coronary syndromes, pregnant patients, patients with cancer and chemotherapy, patients with life-expectancy lower than 24 months, patients with in or out-of-hospital cardiac arrest with ventricular fibrillation as first documented rhythm).
  • At least one ECG tracing that can be exported in raw data.
  • Signed informed consent. Patients unable to consent, it will be requested to an authorized relative.

You may not qualify if:

  • Unwillingness or inability to sign study written informed consent.
  • Unavailable or suboptimal quality of the electrocardiographic signal in raw data.
