How to analyze an EKG rhythm strip in 6 steps

An EKG, or ECG (electrocardiogram), is a non-invasive test that measures the electrical activity of the heart. Analyzing an EKG rhythm is an important skill for healthcare professionals, as it can help diagnose various cardiac conditions. In this video, we will be discussing six steps to help you analyze an EKG rhythm.

Steps to analyze an EKG strip:
Step 1: Determine the heart rate
The first step is to determine the heart rate by counting the number of QRS complexes in a six-second interval and multiplying by 10 to obtain the beats per minute. Alternatively, you can count the number of large squares (5 mm) between two QRS complexes and divide that number into 300 to obtain the heart rate.
Step 2: Assess the rhythm
The second step is to assess the rhythm. Determine if the rhythm is regular or irregular. Look for patterns in the timing of the QRS complexes. An irregular rhythm may indicate atrial fibrillation or other arrhythmias.
Step 3: Identify the P wave
The third step is to identify the P wave. Look for the presence and morphology of the P wave. The P wave should be upright in leads II, III, and aVF, and should precede each QRS complex.
Step 4: Measure the PR interval
The fourth step is to measure the PR interval. Measure the distance between the beginning of the P wave and the beginning of the QRS complex. A normal PR interval is between 0.12 and 0.20 seconds. An abnormal PR interval may indicate an atrioventricular block.
Step 5: Assess the QRS complex
The fifth step is to assess the QRS complex. Determine the duration and morphology of the QRS complex. A normal QRS complex duration is between 0.06 and 0.10 seconds. A wide QRS complex may indicate ventricular tachycardia or bundle branch block.
Step 6: Interpret the overall rhythm
The final step is to interpret the overall rhythm. Based on the above findings, determine the overall rhythm. Some common rhythms include sinus rhythm, atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular tachycardia, and ventricular fibrillation. It is important to note that interpreting an EKG rhythm can be complex and should be done by a qualified healthcare professional.
Conclusion:
In conclusion, analyzing an EKG rhythm can help diagnose various cardiac conditions. By following these six steps, you can systematically analyze an EKG rhythm and arrive at a diagnosis or interpretation of the cardiac rhythm. Remember that interpreting an EKG rhythm should be done by a qualified healthcare professional. Thank you for watching our video on how to analyze an EKG rhythm.
