EKG HR Calculation - 6 Second Method

Which method cannot be used for irregular rhythms?

• QRS counting method

• Peak interval method

• Six second method

• 1500 method and 300 method

What is atrial fibrillation characterized by?

• Irregular rhythm

• Regular rhythm

• Fast heart rate

• Slow heart rate

How can you tell if a rhythm is irregular?

• By measuring the height of the QRS complex

• By counting the number of peaks

• By looking at the RR intervals

• By the color of the EKG strip

What is the time interval associated with each small box on an EKG strip?

• 0.04 seconds

• 0.02 seconds

• 0.08 seconds

• 0.06 seconds

How many small boxes make up the entire length of the EKG strip mentioned?

• 250

• 150

• 200

• 100

What is the average heart rate calculated using the six second method in the video?

• 120 beats per minute

• 80 beats per minute

• 60 beats per minute

• 100 beats per minute

Why is the heart rate obtained using the six second method considered an average?

• Because it's calculated over a long period

• Because the rhythm is irregular

• Because it's an estimation

• Because it uses a large sample of QRS complexes
