What differentiates the heart rate response in neurogenic shock from other types of shock?
Understand the Problem
The question is asking about the specific characteristics of heart rate response in neurogenic shock compared to other shock types, focusing on physiological differences.
Answer
Neurogenic shock causes bradycardia (slow heart rate), unlike other types of shock that cause tachycardia (fast heart rate).
Neurogenic shock is characterized by bradycardia (slow heart rate) due to the loss of sympathetic tone, compared to hypovolemic shock, which typically presents with tachycardia (fast heart rate).
Answer for screen readers
Neurogenic shock is characterized by bradycardia (slow heart rate) due to the loss of sympathetic tone, compared to hypovolemic shock, which typically presents with tachycardia (fast heart rate).
More Information
Bradycardia in neurogenic shock occurs because of unopposed parasympathetic stimulation due to the loss of sympathetic tone, which is different from the tachycardia seen in other types of shock such as hypovolemic or septic shock.
Tips
A common mistake is to assume that all types of shock lead to an increased heart rate. Recognizing that neurogenic shock results in a slow heart rate due to loss of sympathetic nerve activity is crucial.
