Answer to Question 1

ANS: C
-Adrenergic blocking agents block stimulation by the sympathetic nervous system, causing the heart to slow down its rate. This can lead to sinus bradycardia.

Answer to Question 2

ANS: A
Atrial fibrillation is characterized by gross irregularities in both atrial and ventricular depolariza-tion. The P waves have been replaced by fibrillatory waves, which have caused an undulation of the baseline. Not every atrial depolarization has been transmitted by the atrioventricular node.
