A member asked:
My son had an ekg done twice when he was extremely nervous. could this make a qt interval longer? his heart rate was normal but he was super nervous.
3 doctors weighed in across 2 answers
Qt interval: If he had a normal heart rate there would have been no effect on his q-t interval despite his nervousness.

Not really.: Prolonged qtc should always be investigated, and even more so in boys. Genetic tests are available only for known varieties of lqts; there are many cases that do not fit in the known categories.
