A member asked:

When u say that its common to have xtrabeats from atria do they usually come from the sinus or r they ectopic? if u have ectopic r they more malign?

A doctor has provided 1 answer

Ectopic: We don't generally talk about "extra" beats coming from the sinus node, as those are normal sinus beats. Rather, extra beats or PACs come from an ectopic focus, but isolated PACs are generally a common and benign finding.
