How to Read an EKG (Made Easy)

To effectively read an EKG, follow these essential steps:

1. Identify the Rhythm: Determine if the rhythm is regular or irregular by measuring the distance between R waves.

2. Measure the Heart Rate: Calculate the heart rate using the formula: 300 divided by the number of large boxes between R waves.

3. Examine the P Waves: Check for the presence of P waves and ensure they precede each QRS complex, indicating atrial depolarization.

4. Analyze the PR Interval: Measure the PR interval to assess conduction from the atria to the ventricles; it should be between 0.12 to 0.20 seconds.

5. Evaluate the QRS Complex: Look at the duration and morphology of the QRS complex, which should be less than 0.12 seconds in a normal EKG.

6. Assess the ST Segment: Check for elevation or depression of the ST segment, which can indicate myocardial ischemia or infarction.

7. Look at the T Waves: Observe the T waves for their shape and direction, which can provide insight into repolarization abnormalities.
