A wide QRS complex is determined by a measurement of:

• 0.12 seconds or greater

• 0.04 seconds or greater

• 0.11 seconds or less

• 0.08 seconds or less

The PR interval is considered normal if it is between:

• 0.20 and 0.24 seconds

• 0.04 and 0.08 seconds

• 0.12 and 0.20 seconds

• 0.02 and 0.12 seconds

The point where the QRS complex meets the ST segment is commonly referred to as the:

• J point

• Q point

• S point

• P point

The normal heart rate is _________ beats per minute.

• 40 - 120

• 60 - 100

• 20 - 40

• 40 - 60

Step one of the 5-step approach for EKG interpretation is the:

• Heart rate

• Heart rhythm

• PRI

• QRS complex

R to R intervals that exhibit no similarity are termed:

• Occasionally irregular

• Regular

• Irregularly irregular

• Regularly irregular

After making the determination utilizing the R-R interval, you then divide that into __________ to get your rate.

• 100

• 200

• 300

• 400

The sequential beating of the heart as a result of the generation of electrical impulses is called:

• Heart regularity

• Heart system

• Heart rhythm

• Heart rate

When utilizing the R-R interval method to calculate the heart rate, you count the number of __________ between two R waves.

• Large boxes

• Small boxes

A normal or narrow QRS complex indicates that the impulse was not formed in the ventricles and is termed:

• Supraventricular

• Aberrant conduction

• Idioventricular

• Midventricular
