Montgomery · Answer 1

B) hypertension and bradycardia.

Explanation:

Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.

The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.

Thus, Option-B is the correct answer.
