QT varies w/ HR: Your qt interval will vary w/ your heart rate, as well as certain electrolytes and medications. Yours is in the normal range, deadly arrhythmias usually occur when the qt is too long, not too short, so unless there is some other reason to be at risk for v. Fib., like structural heart disease, your risk should be low.

Anxiety: Your qt interval is fine, why are you so concerned about it? Is there a family history of problems?
