ECG's

Question 1

How do you calculate the rate of an ECG?

Answer 1

Count the number of big squaresin an R-R interval and divide 300 by this number

Question 2

How do you calculate the PR inteval?

Answer 2

Measure form the start of the P wave to the start of the QRS complex

Question 3

how long is a normal QRS complex?

Answer 3

0.12 seconds or 3 small boxes

Question 4

What do abnormally large or abnormally long QRS complexes suggest?

Answer 4

•Abnormally large → ventricular hypertrophy •Abnormally broad → ventricular conduction defect BBB.

Question 5

How long should the PR interval be?

Answer 5

No more than 5 small squares (0.2 seconds)

Question 6

If the PR interval is longer than 5 small squares, what does this suggest?

Answer 6

problems in conduction from the SA node to the AV node → Type 1 heart block
