Would it be good advice to do vagal maneuvers if someone is having a fast heart rate?

In brief: Maybe
Depends on the cause of the fast heart rate.
If the rhythm is normal but fast, the rate will simply slow and come right back (no net effect). Same for atrial fib and flutter. But if the fast hr is due to pat/svt (atrial tachycardia), the vagal maneuver may break the rhythm and restore normal rate. It's worth a try. Vagal maneuvers will have no effect on ventricular rhythms.
