can "r on t" phenomenon happen in an interpolated pvc?

[sek978]

During my recovery phase of a stress test, I had an interpolated pvc that also was an r on t phenomenon. The technician and doctor didn't tell me, but when I requested my records it is on the ecg recordings.

Can anyone share any information about this?

Thank you so much for your thoughts, whenever I get waves of pvcs, they still drive me crazy.
Happy fourth of july

Yes. It often / usually does, because the R on T beat is so early that it doesn't interrupt the next sinus beat.

That said, it's hard to evaluate if a PVC actually is R on T, and if it is, it's not necessarily dangerous. My cardiologist said that R on T isn't dangerous in a healthy heart, but I guess there is lots of discussion about the subject. When the doctors are doing an EP study, they provoke R on T beats to see if any arrhythmia is triggered. Usually it's not.

I would ask the doctor if your PVC actually was R on T, and if it was, what may be the cause and if it increases your risk of any cardiac events.
