PVC caught on AliveCor?

I don't know how it can pick things up through the fingertips but it has definitely caught my PACs and now I think this is a PVC?

Pretty impressive from such a small device.

The last image shows a supraventricular ectopic beat, yes.

The first image I'm not sure about. It's not PACs. If a PAC came this early, it would have been blocked by the AV node. I don't think it's anything, really, but if it is a PVC, it should be investigated because the coupling interval would be so short. It's known as R on T.

Use Google to find a cardiologist online (I don't think there are any on this board anymore) who can take a look. Most likely there's nothing to worry about and I'm sorry if I'm triggering your anxiety now, but better to be safe in my opinion.

This is what I think is a PAC which I recorded last month.

Thing that's worrying me is you can always make out the T wave on the AliveCor, even if I'm moving my hands on purpose. It is very sensitive to movement but my hands were dead still during that recording (in the OP) and as I said, whenever the recording does go a bit haywire, even for no reason, I can always see the T wave one way or another. I've never seen this before either.

If I show this to a doctor they will probably laugh me out the room and think an AliveCor is a little gadget I bought off eBay. I know it isn't particularly reliable or high quality but I'm pretty sure it picks up PACs, so surely it can pick up PVCs.

Obviously I could be completely wrong about everything.

I believe that app is designed to pick up afib so not sure it reads ectopic beats well.  If it isn't simple some sort of disturbance I would suspect they would be more likely pacs as opposed to pvcs since you don't see the full beat pause but check with your doctor if you get a lot of them.

I just wanted to clarify, I don't really think these are PVCs. They lack a repolarization wave, and the second beat doesn't look like a PVC at all. And they (especially the first one) are simply too early. I have never heard about a PVC with a coupling interval that short.

My guess is that what you have recorded is some sort of artifact, possibly from another muscle. When you are using an 1 lead EKG which measures current from finger to finger, errors may occur.

But I'm not a doctor, so I would definitely recommend asking someone who is :-)

Hard to say what this is.

If they are PVCs, they have an extremely short coupling interval from the previous beat. As you can see, they fall on the peak of the previous T wave.

It could also be electrical disturbance (for example a muscle twitch in your arm).

I would recommend that you show your recording to a physician. If this is PVCs, a physician should evaluate them because such PVCs (falling on the T wave) can in some cases involve risk.
