Question

The intrinsic rate of the Purkinje fibers is _____ beats/min.

a) 60-100
b) 40-60
c) 20-40
d) 100-120

Answer 1

The intrinsic rate of the Purkinje fibers is 15-20 beats per minute, which falls under option c) 20-40 beats/min.

Step-by-step explanation:

The question pertains to the intrinsic rate of the Purkinje fibers, which is part of the cardiac conduction system responsible for controlling heart rhythms. According to the provided information, the Purkinje fibers would fire at an intrinsic rate of 15-20 beats per minute. Therefore, the correct answer to the question 'The intrinsic rate of the Purkinje fibers is _____ beats/min.' would be c) 20-40 beats/min.
