Here's why it matters

An electrocardiogram (EKG or ECG) is a test that records the electrical activity of the heart. It helps healthcare providers detect and study heart problems such as heart attacks, arrhythmias, and heart failure. 

After recording an ECG, students should know how to identify waveform irregularities and respond appropriately (e.g., informing the healthcare provider, retaking the ECG due to artifacts, and so forth).

To be successful, students must understand the ECG's layout, how the grid works, and the anatomy of the cardiac waveforms. 

Here's an opportunity

Sarah's ECG Challenge presents a fun way for students to confirm their ability to use the ECG grid to measure cardiac waveforms. Watch the brief video for the context, then complete the activity.

Keep going!

Congratulations on completing one of several activities in our Measuring Electrocardiogram Waveforms module. Did you do well with the activity? If not, don't worry! You'll master the necessary skills quickly as you complete the lessons in the module. 

The step-by-step lessons and engaging activities will help you: 

  • identify the layout and elements of a 12-lead ECG
  • arrange and mount ECG strips on a mounting board
  • practice measuring the height, amplitude, width, and duration of the P waves, T waves, PR and QT intervals, and the QRS complex

You can find the Measuring Electrocardiogram Waveforms module and others in our flagship course—The Ultimate Head Start in Healthcare Career Training.
