Neurocardiac syncope can be precipitated by which of the following?

• A. Shortness of breath on exertion
• B. Paresthesia, cauda equina may be present
• C. Tremor in the hands
• D. Hearing loss

Answer: (B)

Neurocardiac syncope happens when a neurologic process disrupts autonomic control of heart rate and vascular tone, leading to a drop in blood pressure and fainting. Paresthesias and signs suggesting cauda equina indicate a neuroanatomic problem affecting the nervous system, which can provoke this kind of autonomic instability. The other symptoms—shortness of breath on exertion, tremor, or hearing loss—fit more with primary cardiopulmonary, motor, or sensory issues and do not inherently point to a neurogenic cause of syncope.
