Summary Introduction
To review:
The given blank space in the statement using the following ECG graph.
QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
Electrocardiogram (ECG) is a diagnostic test machine used to monitor the heart rate of the patients. It records the electrical signals produced by the heartbeat in the form of wave components, such as P, Q, R, S, T, and U. ECG interpretation is done by doctors through a systemic approach.

One of the following is a life-threatening arrhythmia and an absolute emergency that should immediately be notified by the MA to the physician in the event it appears in the EKG strips.
One of the following is a life-threatening arrhythmia and an absolute emergency that should immediately be notified by the MA to the physician in the event it appears in the EKG strips.
Sinus rhythm
Sinus tachycardia
Sinus bradycardia
Ventricular fibrillation
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 to your classmates 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?
Educate a patient: What you will do before, during, and after an…
