a true
b false

Answer 1

Junctional bradycardia is a condition where the heart rate drops below 60 beats per minute. It is true that a heart rate must be less than 20 to be considered junctional bradycardia. Bradycardia is a condition with a heart rate lower than 60 beats per minute.

Step-by-step explanation:

Junctional bradycardia is a condition in which the heart rate drops below 60 beats per minute. It is true that the heart rate must be less than 20 for it to be considered junctional bradycardia. Bradycardia is generally defined as having a heart rate lower than 60 beats per minute, and when the heart rate falls much below 50 beats per minute, it indicates a condition called bradycardia. In some cases, bradycardia can lead to insufficient blood supply to vital tissues and ultimately result in unconsciousness or death.
