Introduction:
The diagnostic test machine that is used to monitor a patient’s heart rate is known as Electrocardiogram (ECG). The ECG records the electrical signals, which are in the form of wave components, such as P, Q, R, S, T, and U. The doctors interpret this ECG through a systemic approach.

The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. 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?

Electrocardiogram is also called ECG. It is a test that assesses the electrical activity of the heart through electrodes attached to the skin. The figure (A) on the X axis - represents the time and on the Y axis - the mV of an electrocardiogram. Image B represents the electrocardiogram of a rested adult patient. Based on the images, identify and comment on the diagnosis.
