# How do you interpret an ECG?

## How do you interpret an ECG?

When interpreting the heart rhythm, you should look for P waves, which is a sign of atrial excitation. When every P wave is followed by a QRS complex, the ECG shows sinus rhythm. If the P waves are irregular, sinus arrhythmia is likely present.

What a normal ECG reading should look like?

Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).

### What is a 12 lead ECG?

A 12-lead electrocardiogram (ECG) is a medical test that is recorded using leads, or nodes, attached to the body. Electrocardiograms, sometimes referred to as ECGs, capture the electrical activity of the heart and transfer it to graphed paper.

What are normal ECG test results?

The normal range of the ECG differed between men and women: heart rate 49 to 100 bpm vs. 55 to 108 bpm, P wave duration 81 to 130 ms vs. 84 to 130 ms, PR interval 119 to 210 ms vs. 120 to 202 ms, QRS duration 74 to 110 ms vs.

## What is an abnormal ECG reading?

An abnormal ECG can mean many things. Sometimes an ECG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal ECG can signal a medical emergency, such as a myocardial infarction /heart attack or a dangerous arrhythmia.

How do you read ECG results?

Standard ECG paper allows an approximate estimation of the heart rate (HR) from an ECG recording. Each second of time is represented by 250 mm (5 large squares) along the horizontal axis. So if the number of large squares between each QRS complex is: 5 – the HR is 60 beats per minute.

### What is the abnormal ECG report?

The Six-Step Method for 12-Lead ECG Interpretation Rate and Rhythm. What is the rate? Axis Determination. Is the front plane axis in the normal range (left inferior axis)? QRS Duration (Intervals) If you’ve followed the first two steps there’s a good chance you’ve already picked up on a prolonged PR-interval or wide QRS complex, but “Step 3” Morphology. STEMI Mimics.

## What is EKG 12 lead Stat?

The main purpose of the 12-lead ECG is to screen patients for possible cardiac ischemia . It helps EMS and hospital staff to quickly identify patients who have STEMI (ST elevation myocardial infarction or in other words, heart attack) and perform appropriate medical intervention based on initial readings.
