Heart model and EKG
Students will build a heart-flow model and record an EKG and pulse to relate structure to function.
Annotated EKG trace with P, QRS, and T waves labeled and linked to cardiac cycle phases, plus a data table recording resting pulse and blood pressure with units.

💡 Big idea: Structure and function are inseparable: the sequence of chambers and valves is directly visible in an EKG trace.
- 0-10Safety and equipment orientation: EKG leads, blood-pressure cuff, pulse oximeter
- 10-22Assemble or label heart model; demonstrate one-way valve flow
- 22-42Record resting EKG trace; identify and label P, QRS, and T waves
- 42-55Measure resting pulse and blood pressure; record with units
- 55-68Connect EKG wave sequence to cardiac cycle phases in notebook diagram
- 68-80Cleanup; submit annotated EKG trace and data table
- • Today you will connect the anatomy you mapped yesterday to real electrical and mechanical data from your own body.
- • An EKG is not just a squiggly line; each peak maps onto a specific event in the cardiac cycle.
- • You will also measure blood pressure and pulse, the two most commonly recorded vital signs in clinical settings.
- • Record all measurements carefully; you will use them in your CER tomorrow.
- 1Assemble or label a working heart model.
- 2Demonstrate blood flow through chambers and valves.
- 3Record a resting EKG trace and identify the heartbeat waves.
- 4Measure pulse and estimate blood pressure.
- 5Connect the EKG pattern to the cardiac cycle phases.
- • Model correctly shows one-way flow through valves.
- • EKG waves are linked to cardiac cycle phases.
- • The P wave represents atrial depolarization; the QRS complex represents ventricular depolarization; the T wave represents ventricular repolarization.
- • Blood pressure is expressed as systolic (ventricle contracting) over diastolic (ventricle relaxing) in mmHg.
- • Heart rate and blood pressure are vital signs that clinicians use to assess cardiovascular health.

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete any EKG or heart-model lab check-in prompt in Lesson 3.1 Cardiopulmonary Connection on myPLTW that accompanies today's lab; finish it after labeling your EKG waves.
Mark the lab check-in complete in myPLTW after submitting your labeled EKG trace and blood-pressure readings.
Cardiac-cycle task is done; today the lab check-in should show complete.

Lab & supplies
- • Do not apply EKG electrodes over broken skin, rashes, or wounds; inform the teacher if this applies to you.
- • Blood-pressure cuffs should not be inflated above the recommended maximum; follow teacher instructions.
- • Students with known cardiac conditions should check with the teacher before participating in EKG recording.
- • All electrode pads are single-use and personal; do not share between students.
- • Treat all equipment carefully; report any damage to the teacher immediately.

What to do if you were absent
Record a resting EKG and pulse, then label the heartbeat waves and tie them to chamber contraction in your heart model.
