Introduction:
The electrocardiogram (ECG) is the graphical representation of a patient’s heart rate that records the electrical signals of the heart. It contains wave components, such as P, Q, R, S, T, and U, which are present in the wave. The ECG interpretation is done when a patient is in serious condition.

This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. How would you explain how to perform an EKG (steps)? Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor?
