The Anatomy of the ECG/ EKG & 5-Step method of interpreting a Basic ECG/ EKG

This is the second lesson in our Basic ECG/ EKG series.

In this video, we review the Anatomy of the ECG/ EKG and the 5-Step method of interpreting a Basic ECG/ EKG.

P-wave: Atrial Depolarization/ Contraction of the Atria

PR-interval: The time from the beginning of the P wave to the beginning of the QRS complex.

QRS: Ventricular Depolarization/ Contraction of the Ventricles

T-wave: Ventricular Repolorization

5-Step method of Interpreting a Basic ECG/EKG:

1. Rate?

• Normal (60-100)

• Bradycardia (<60)

• Tachycardia ( >100)

2. Rhythm?

• Regular (R-R distances constant)

• Irregular (R-R distances varies)
  

3. Are there P-waves?

• One P-wave for every QRS?

• 1:1 conduction?

4. PR Interval ?

• Normal= 0.12- 0.20 seconds

• 3-5 small boxes

5. QRS normal or wide?

• Normal= ≤ 0.12 seconds

• ≤ 3 small boxes
