  1. What kind of recording does the Apple Watch ECG app produce according to Apple's documentation?
    • A waveform similar to a single-lead ECG
    • A full coronary CT angiogram
    • A cholesterol measurement from a blood sample
    • A twelve-lead ECG with twelve independent waveforms
  2. What task did the 2019 Mayo AI-enabled ECG study evaluate?
    • Measuring blood cholesterol without a blood test
    • Performing cardiac surgery autonomously
    • Screening for low left-ventricular ejection fraction from ECG data
    • Detecting every heart condition from every normal-looking tracing
  3. What physical information supplies the input to an ECG-based cardiac model?
    • Only the patient's appointment filename
    • Only the colors in an ultrasound image
    • Only the dimensions of a CT scanner's casing
    • A time series representing the heart's electrical activity
  4. What does HeartFlow describe its FFRCT analysis as estimating from coronary CT-derived anatomy?
    • The patient's genetic sequence directly from image filenames
    • Coronary physiology using deep-learning and computational-fluid-dynamics methods
    • Every cardiac diagnosis without clinical interpretation
    • The exact time of every future cardiac event
  5. What was compared in the 2023 blinded randomized echocardiography trial discussed here?
    • An AI prescription against automatic surgery in every patient
    • A wearable ECG against a cholesterol blood test
    • Initial AI and sonographer ejection-fraction assessments followed by cardiologist evaluation
    • Whether images could be eliminated from echocardiography
  6. Why should a cardiac AI evaluation describe its patient population and clinical setting?
    • Performance in the studied data may not transfer unchanged to other patients or workflows
    • One reported score guarantees equal performance in every setting
    • Clinical setting cannot affect input quality
    • A model name alone specifies every intended use
  7. Which capability does Apple's ECG app documentation explicitly exclude?
    • Recording an ECG waveform for the specified supported device
    • Detecting a heart attack
    • Offering its specified rhythm classification
    • Exporting a recording for review
  8. How should an ECG-based low-ejection-fraction screening score be distinguished from an imaging measurement?
    • It directly measures every ventricular volume without imaging
    • It establishes that every CT-based result is interchangeable
    • It removes the need to understand the model's prediction target
    • It predicts a screening target from electrical data rather than directly measuring ventricular volumes from images
