Answer to Question 1

A
Adenosine occurs endogenously in the body as a building block of adenosine triphosphate (ATP). Given in intravenous boluses, adenosine slows conduction through the atrioventricular (AV) node, causing transient AV block. It is used clinically to convert supraventricular tachycardias and to facilitate the differential diagnosis of rapid dysrhythmias.

Answer to Question 2

B
The major factor underlying atrial flutter symptoms is the ventricular response rate. If the atrial rate is 300 and the atrioventricular (AV) conduction ratio is 4:1, the ventricular response rate is 75 beats/min and should be well tolerated. If, on the other hand, the atrial rate is 300 beats/min but the AV conduction ratio is 2:1, the corresponding ventricular rate of 150 beats/min may cause angina, acute heart failure, or other signs of cardiac decompensation.
