Measuring Electrocardiogram Waveforms

How to Use an ECG Grid to Measure ECG Waves and Intervals

Have you ever asked yourself:

  • What information is commonly found on a 12-Lead ECG?
  • What do the little boxes on the ECG represent?
  • How do I use the ECG grid to measure the different heart waves?

If you seek answers to these questions, then this course is for you.

Don't Worry. This course is not about learning the ENTIRE subject of electrocardiography. Instead, this course targets one specific skill that many beginning students find challenging—using an ECG grid to measure waveforms (P wave, T wave, PR interval, QT interval, QRS complex).
