  c. Calculate the number of small squares between one QRS complex and the next and divide into 1500.
  d. Use the 3-second markers to count the number of QRS complexes in 6 seconds and multiply by 10.

Question 2

Answer to Question 1

ANS: D
This is the quickest way to determine the ventricular rate for a patient with a regular rhythm. All the other methods are accurate, but take longer.

Answer to Question 2

ANS: A
The P wave represents the depolarization of the atria. The P-R interval represents depolarization of the atria, atrioventricular (AV) node, bundle of His, bundle branches, and the Purkinje fibers. The QRS represents ventricular depolarization. The Q wave is the first negative deflection following the P wave and should be narrow and short.
