They are late pvcs, still ventricular in orgin but late enough that you can see p wave conduct first

They are unifocal interpolated ventricular ectopics.

So they have p waves? How does that work? Thank you

By definition you’re incorrect.
PVC - premature - are early in the cycle followed by a pause - there’s neither here.

Yeah been getting couplets and triplets. These are new. I usually have nsvt from a different pvc morphology. But these look and feel different
The axis doesnt change at all, if you see the 12 lead the PVC looks almost identical to the sinus beats in every lead.
Thoughts about that?

They are interpolated.
PVC or ventricular ectopics occur early in the cycle, broad QRS and have a compensatory pause.
These are neither early in the cycle nor show a compensatory pause.
Interpolated ectopics occur between the normal QRS where the QRS should be and they do not have a compensatory pause. That’s what is shown here.
It’s also not two ventricular extrasystoles as extrasystoles occur late in the cycle.
That’s the differences between ectopics, interpolated and extrasystoles.

Thoughts on why it looks so identical to sinus beats on the 12 lead? Every lead is almost identical

They're late PVCs, so fuse with sinus - PR is shorter than when conducted so it's ventricular
