Question 2

The absolute refractory period begins with the onset of the _____ and terminates _____.
 
  a. P wave; with the end of the QRS complex
  b. QRS complex; at approximately the apex of the T wave
  c. QRS complex; with the end of the T wave
  d. P wave; with the beginning of the QRS complex

Answer to Question 1

Rhythm Ventricular rhythm is essentially regular.
Rate Ventricular rate 20 to 40 beats/min.
P waves Usually absent or, with retrograde conduction to the atria; may appear after the QRS (usually upright in the ST segment or T wave).
PR interval None.
QRS duration 0.12 seconds or greater; the T wave is frequently in the opposite direction of the QRS complex.

Answer to Question 2

B
On the ECG, the absolute refractory period corresponds with the onset of the QRS complex to the peak of the T wave.
