A member asked:

How is svt distinguished from normal fast heart rhythm on a holter monitor?

Simple.: Svt has a very regular beat whereas a fast heart beat displays subtle but measurable variation beat to beat. Svt has sudden onset and offset. A normal heart beat speeds up and slows down gradually.

Context: The context In which the rhythm speeds up, the speed of fast rhythm onset and termination, and the shape of the waves on the rhythm strip can help distinguish an abnormal rhythm from normal.
