Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or female who are 22 years of age or older
  • Subject able to read, understand, and provide written informed consent
  • Subject willing and able to participate in the study procedures as described in the consent form
  • Subject able to communicate effectively with and willing to follow instructions from the study staff

Exclusion criteria

  • Subject with an implanted electrical device (i.e. pacemaker, ICD …), whether active or inactive
  • Pathologic disorders that may affect motricity resulting in significant hands tremor that prevents subject from being able to hold still (e.g. Parkinson disease)
  • Myocardial Infarction (MI) within 90 days prior to the enrollment
  • Pulmonary embolism or pulmonary infarction within 90 days prior to the enrollment
  • Stroke or Transient Ischemic Attack (TIA) within 90 days prior to the enrollment
  • Active or history of life-threatening rhythms as determined by investigators (e.g. ventricular tachycardia, ventricular fibrillation, 3rd degree heart block)
  • Any cardiovascular disease that investigators would consider as a risk to subject or renders data uninterpretable (e.g. recent or ongoing unstable angina, decompensated heart failure, active myocarditis or pericarditis)
  • Active or symptomatic skin disease on Schiller electrode attachment sites or fingertips which would be in contact with BeamO electrodes (e.g. eczema, rosacea, impetigo, dermatomyositis or allergic contact dermatitis)
  • Known sensitivity to medical adhesives, isopropyl alcohol,, electrocardiogram (ECG) electrodes, including known allergy or sensitivity to stainless steel (used in BeamO electrodes).

Treatment and study plan

Investigational Device (Withings SCT02) 30 second Electrocardiogram recording

Device

30 second ECG recording with investigational device (Withings SCT02)

Reference Device (Schiller Cardiovit FT-1) 30 second Electrocardiogram recording

Device

30 second ECG recording with reference device (Schiller Cardiovit FT-1)

Primary outcomes

  1. Co-primary outcome 1 - Sensitivity of Investigational Device

    Time frame: 10 months

    Sensitivity (percentage of true positives) in detecting AF from conclusive recordings generated by the software under test, that is recordings resulting in a classification of AF or SR by the IMD, compared to the reference 12-lead ECG.

  2. Co-primary outcome 2 - Specificity of Investigational Device

    Time frame: 10 months

    Specificity (percentage of true negatives) in detecting AF from conclusive recordings generated by the software under test, that is recordings resulting in a classification of AF or SR by the IMD, compared to the reference 12-lead ECG.

Secondary outcomes

  1. Rhythm classification by ranges of heart rate

    Time frame: 10 months

    On pairs of strips such that the rhythm classification of the 12-lead ECG is either SR or AF and such that the strip generated by the IMD is classified as either SR or AF, the classification into four heart rate subgroups will be evaluated.

    • Sinus Rhythm, (50-99 bpm)
    • High Heart Rate (No signs of AFib) (100-150 bpm)
    • Atrial Fibrillation (50-99 bpm),
    • Atrial Fibrillation (100-150 bpm)
  2. Quality of plots measured by the IMD - ECG Waveform Visibility

    Time frame: 10 months

    Clinical Equivalence of ECG waveforms will be qualitatively and quantitatively assessed between the 1-lead generated by the IMD and the lead I of the 12-lead reference ECG determined by certified cardiologists. Equivalence will be evaluated by FV : Fraction of concordant assessments of visibility between the IMD and the reference

  3. Quality of plots measured by the IMD - ECG Waveforms Polarity

    Time frame: 10 months

    On waveforms with waves that are Visible, Clinical Equivalence of ECG waveforms will be qualitatively and quantitatively assessed between the 1-lead generated by the IMD and the lead I of the 12-lead reference ECG determined by certified cardiologists. Equivalence will be evaluated by FP : Fraction of concordant assessment of polarity between IMD and reference

  4. Quality of plots measured by the IMD - ECG Waveforms Intervals

    Time frame: 10 months

    Determine the equivalence of PR, QRS and QT intervals durations between the lead I of the IMD and the lead I of the reference ECG determined by an independent board of certified cardiologists. Duration error will be calculated.

  5. Quality of plots measured by the IMD - Heart Rate calculation

    Time frame: 10 months

    Determine the equivalence of the heart rate (HR) calculated by the IMD and the HR measured by an independent board of certified cardiologists or cardiology technicians on the ECG of the reference.
