Answer to Question 1

F
Macroreentry circuits and microreentry circuits are two main types of reentry circuits. If the reentry circuit involves conduction through a large area of the heart, such as the entire right or left atrium, it is called a macroreentry circuit. A reentry circuit involving conduction within a small area is called a microreentry circuit.

Answer to Question 2
