Which of the following is a symptom of PAH?

  1. Hyperthermia

  2. Bradycardia

  3. Syncope

  4. Hypertension

The correct answer is: Syncope

Syncope is a symptom of PAH because it refers to fainting or loss of consciousness, which can be caused by a sudden drop in blood pressure as a result of the heart's inability to pump enough oxygenated blood to the body. Options A and D, hyperthermia and hypertension, are not symptoms of PAH as they refer to elevated body temperature and high blood pressure, respectively, which may be present in other conditions but are not specifically associated with PAH. Option B, bradycardia, refers to a slow heart rate, which may occur as a response to PAH but is not a direct symptom of the condition. Thus, option C, syncope, is the correct answer as it is a specific and direct symptom of PAH.
