Verification of exercise-induced transient postural tachycardia phenotype in Gulf War Illness.

Researchers found that about one-fourth of Gulf War Illness patients developed an unusual heart rate response after exercise: their heart raced when they stood up, even though this didn't happen before exercise. This temporary condition, called the START phenotype, appeared around 2 hours after exercise and was different from a similar condition called POTS that some patients had continuously. This discovery suggests that exercise can trigger a specific cardiovascular problem in some Gulf War Illness patients.
