How do you determine whether the atrial rhythm on an ECG tracing is regular or irregular?
 
  a. Compare QT intervals.
  b. Compare PR intervals.
  c. Compare R to R intervals.
  d. Compare P to P intervals.

Question 2

When you read a 12-lead ECG from left to right, the ECG tracing is continuous.
 
  Indicate whether the statement is true or false

Answer to Question 1

D
To evaluate the regularity of the atrial rhythm on a rhythm strip, the interval between two consecutive P waves is measured. The distance between succeeding P-P intervals is measured and compared. If the atrial rhythm is regular, the P-P intervals will measure the same.

Answer to Question 2

T
When viewing a 12-lead ECG, leads that line up vertically are simultaneous recordings of the same beat. When you read the 12-lead ECG from left to right, the ECG tracing is continuous. As you switch from one lead to the next, it is still continuous.
