Optional order · take one example at a time. Completion records what you studied, not a proficiency score.

  1. Start with normal

    Describe the normal tracing and locate its waves, intervals and lead labels.

    Suggested preparation: No prior lesson needed · 0 / 1 studied
  2. Common rhythms

    Compare rhythm timing and the relationship between atrial and ventricular activity.

    Suggested preparation: Start with normal · 0 / 6 studied
  3. Conduction and intervals

    Work through the existing interval, conduction and ectopy findings.

    Suggested preparation: Common rhythms · 0 / 12 studied
  4. ST–T patterns

    Compare the distribution of changes and read each example’s interpretation limits.
