## How to read an EKG? Use the basic method by Dr. ROIG.

Created by team@ekgdx.com on Oct. 3, 2020 In the beginning, most physicians, nurses and students experience problems when performing an adequate interpretation of an EKG, and this is due (among other factors) to the lack of organization when interpreting an EKG.

To solve this GLOBAL problem, Dr Roig created a basic method that will guide you in a simple way. The only thing you have to do, is to remember his last name (ROIG).

Now we will explain the steps of the ROIG method and then we will use one sample to see how it works.

Use the basic method by Dr. ROIG by remembering his last name.

Rate Observe the rhythm Intervals Go for the signs of Myocardial Infarction Each person has their way of reading an EKG, but if you don't have a specific order, the basic method of Dr. ROIG will help you organize yourself every time you interpret an EKG. As soon your knowledge increases, you should add to the method (second step) the following:

Obseve the rhythm, P:QRS, Axis, Voltage, R progression, and the Chambers enlargment.

After knowing the method, I think we are in a position to see how it works.

Example 1: Use the basic method by Dr. ROIG by remembering his name.

Rate
The first step is to calculate the Heart Rate (HR).
Total QRS x 6 = HR.
If HR > 100 bpm = Tachycardia.
If HR < 60 bpm = Bradycardia.

Observe the rhythm
The second step is to observe the rhythm.
If R-R interval is equal = Regular rhythm.
If R-R interval varies = Irregular rhythm.
If P wave is upright in lead II = Sinus rhythm.

Intervals
The third step is to analyze the intervals.
Check the PR, QRS and QT intervals.
Are they long o short?

Go for the signs of Myocardial Infarction (MI).
The fourth step is to look for MI.
Are there ST elevation?
Are there ST depression in V1-V3?
Are there abnormal Q waves?

EKG Interpretation

Rate: 12 QRS x 6 = 72 bpm (Normal)
Regular rhythm (R-R interval is equal).
Sinus rhythm (upright P wave in lead II)
The intvervals PR, and QT are normal. The QRS is < 0.12 seconds with rSr' pattern in V1 and V2.
No signs of myocardial infarction (absent of ST elevation/depression and absent of Q waves).

This EKG shows a sinus rhythm with an incomplete RBBB (right bundle branch block).

Example 2: Use the basic method by Dr. ROIG by remembering his name.

Rate
The first step is to calculate the Heart Rate (HR).
Total QRS x 6 = HR.
If HR > 100 bpm = Tachycardia.
If HR < 60 bpm = Bradycardia.

Observe the rhythm
The second step is to observe the rhythm.
If R-R interval is equal = Regular rhythm.
If R-R interval varies = Irregular rhythm.
If P wave is upright in lead II = Sinus rhythm.

Intervals
The third step is to analyze the intervals.
Check the PR, QRS and QT intervals.
Are they long o short?

Go for the signs of Myocardial Infarction (MI).
The fourth step is to look for MI.
Are there ST elevation?
Are there ST depression in V1-V3?
Are there abnormal Q waves?

EKG Interpretation

Rate: 20 QRS x 6 = 120 bpm (Tachycardia because HR > 100 bpm).
Regular rhythm (R-R interval is equal).
Sinus rhythm (upright P wave in lead II).
The intvervals PR, QRS and QT are normal.
Are there ST elevation?. There is ST elevation in II, III and aVF with reciprocal changes (ST depression) in aVL. In addition, notice the inverted T waves in the same leads.
Are there ST depression in V1-V3?. No
Are there abnormal Q waves?. There are abnormal Q waves in II, III and aVF.

This is a sinus tachycardia with inferior Q wave MI (Acute).

I hope this method will be useful for you as much as it was for me in the beginning.
