CCMA- Electrocardiogram

This element of the EKG represents ventricular depolarization and contraction, and the blood moving to the lungs and body

• P Wave

• QRS Complex

• T Wave

• PR Interval

This element of the EKG represents the SA node firing, the atria contracting and the blood moving to the ventricles

• T Wave

• P Wave

• PRS Complex

• ST segment

How many electrodes are placed on the patient for a 12 lead EKG?

(a)  

Which picture shows the correct placement for a 12 lead EKG?

• 
• 
• 
• 

This artifact results in irregular spikes throughout the tracing and can be caused by muscle movement from shaking

• Alternating Current Interference

• Somatic Tremor

• Wandering Baseline

• Flat line

This artifact is when the baseline moves from the center of the paper and is caused by poor electrode connection

• Alternating Current Interference

• Somatic Tremor

• Wandering Baseline

• Flat Line

This artifact results in regular spikes in the tracing and is caused by things like lights, computers or cell phones

• Alternating Current Interference

• Somatic Tremor

• Wandering Baseline

• Flat Line

What is the heart rate on this EKG?

(a)  

During this arrhythmia, the atria are contracting at a faster rate than the ventricles

• Sinus Tachycardia

• Atrial Flutter

• Atrial Fibrillation

• Ventricular Fibrillation

During this rhythm, a parts of the heart are quivering and the patient is at an increased risk for blood clots. It is NOT usually considered a medical emergency

• Sinus Bradycardia

• Atrial Flutter

• Atrial Fibrillation

• Ventricular Fibrillation
