Thanks itdood, I showed this to my EP and he thought it was an artifact and not NSVT. In any case, I have a followup stress echo to rule out any structural disease.
pp.s, dangit I wish I could edit posts, I end up doing this ps thing. Anyways, I'm guessing that each of those squares is about 5mm. If that's the case, than I really doubt this strip shows escape rhythm because at most there is only about 1.5 seconds between v-systoles which doesn't fit escape timing (as I understand it). If you can, measure the distance between those squares and post it back, knowing that is needed to interpret the EKG.
p.s., If I had to go out on a limb and detail what escape rhythm feels like (which I've never experienced), I would tell someone it would be a very slow heart rate. 4-7 seconds between each beat, which is a rate of 40-60 bpm, which is what an escape rhythm generates. You see, you can't live without your ventricles beating at that minimum rate. The ventricles have a backup built in just in case the SA beat doesn't signal it to go. This back up paces automatically at a slower rate than the SA node to achieve that sort of backup. It's always there, but because its rate is a bit slower than the SA node, the SA node usually leads the whole thing. The ability for ventricular cells to pace is what causes PVCs, BTW. When a ventricular cell paces faster than this 4-7 second propensity it's called "enhanced automaticity" and this what causes PVCs, but I digress.
Since you are describing a lot of quiver, flip flop, I'm inclined to think that would more match the NSVT profile which is what I see in the bottom strip.
I usually tell people to ask their docs and take their advice but you might want to get a second opinion on that test. Not that NSVT is bad, it's usually benign, but at least get the right answers.
I know enough about EKGs to be dangerous.
Are you sure this graph pertains to the episode of escape beats? The reason I ask is because I *think* I see P waves right before the ventricular waves, which means it wouldn't be an escape beat. But then again, if each of those squares is 25mm, that would mean there was about 7 seconds between some of the ventricular beats which would mean that yes they were escape beats. The spacing between the P and Q waves seems a bit long, which might indicate some AV block, but this is a very amateur guess.
Also, the very bottom strip, that looks like NSVT to me but it would depend on the model of EKG you were wearing.
If I were told I had escape beats I'd be wondering why, either is was blocked (AV block) or the SA node didn't generate it.
The NSVT portion is something I'd ask more about too.
