Heart

Biopac Science Lab comes with three lessons focused on heart activity:

• Lesson 3 — ECG I Electrocardiography: Components of the ECG
  • Lesson 3 introduces the electrocardiograph (ECG) and the recording of the heart’s electrical signal. Students learn about Lead II ECG recording and the components of the ECG complex. They also learn to correlate the electrical events of the ECG (P, Q, R, S & T components) with the mechanical events of the cardiac cycle. After performing a number of tasks designed to promote changes in the ECG complex, students analyze their own ECG recordings.
• Lesson 4 — ECG II Electrocardiography
  • Lesson 4 explains Einthoven’s triangle. Students record Leads I and III while performing a number of tasks designed to change the rhythm of the heart. They then analyze the data and estimate the mean QRS axis and potential.
• Lesson 10 — Aerobic Exercise Physiology
  • In Lesson 10, students record ECG and heart rate under a variety of conditions. Students see how the electrical activity of the heart and their heart rate change to meet changing metabolic demands. Students exercise to elevate heart rate.
