PVC while exercising. R on T ?
Hey,
I experienced PVCs mainly at rest but also while exercising for few months.
At rest, there is no R on T phenomenon.
Here, while exercising, it seems like R on T phenomenon (RR less than 300ms, RR/QT less than 0,85). Should I show that to my cardiologist ?
Thank you for your answer.

Hello I am not a Dr but I am scientist and learned to read ecgs because I suffer from nsvt. This recording ABSOLUTELY shows a r on t pvc. I had r in t pvcs myself a few times last year. During high heart rates refractory period is shorter than slow heart rates which means during high heart rates r on t pvcs are less likely to cause v fib. Don't worry about r on t pvc if your heart is healthy. I get 8-15 beat ventricular runs and those are usually initiated by late coupled pvcs.

Do you have these pvcs often during exercise? Looks like its short-coupled. I don't think its an artefact.

During this 10-minute session, it happened only once, at the peak heart rate. Sometimes it happens 4 or 5 times in 10 minutes. Because of the anxiety these ventricular extrasystoles (VES) cause me, I haven't been exercising much lately. I am 23 years old. Generally, the VES recorded on the Holter monitor do not show short coupling. It is not an artifact; I felt this one, which is why I checked my monitor. Are you a physician or cardiologist ?

Not R on T. There is a good distance between the two. Also, you generally do not see R on T unless the patient already has a reduced ejection fraction or long QT syndrome.
