R on T

[Darfzo]

Hi does anyone know what it means if you have R on T episode shown on a 24hr ECG monitor?

Yes do let the doctor know about your cousin.  I would say you should in the minimum have an echo.  And do please keep us posted.

Hey, many thanks for your information, at least it's looking like NSVT and not VT. I see the cardiologist tue 7th jan so not long now, I don't think I have long QT by my report my QT are within normal range :) I'm not too worried about what this is as there are many people with a lot worse, although I was concerned that sudden death kept popping up while I was trying to research.. My cousin died at 18, he just dropped down dead, later they found he had HOCM, I think I should mention this at the specialist too?
Hopefully from my results it doesn't seem much to be concerned about :) I will let you know what the cardio says :)
Thanks again

Please keep in mind I am not a doctor so I can only go by my own personal research on anything I comment on.  From what I see all this really tells you is that you are having pvcs and short runs of nonsustained ventricular tachycardia.  You had 494 isolated pvcs.  This is not a lot but 85 of them were R on Ts which could have been the trigger for your 55 runs of VT.  Though as you see not all of them triggered VT but enough did to take notice in my opinion.  The good news is the longest it lasted was only 27 beats so you are converting quickly.  You should really have a full workup of your heart to see how it is functioning as well please do discuss with your cardiologist about whether or not you have Long QT.  I believe if you are passing out from any of this you may be fitted with an ICD to keep you out of any dangerous rhythms.  I understand you are young but it could help you live a long life if it is necessary.  They may also try to do an ablation for you to try and correct the spot where the pvcs are coming from.  If yours are unifocal this can be easy to fix.  Considering how many runs you had in a 24 hour period you may be a good candidate for a fix.   Anyways, please discuss this with your cardiologist to find out what it means for your particular case and do let us know how you are doing.  Best of luck and try to not stress if you can.  The stress itself may make things worse.  Hang in there.

R on T means that your pvc started on the T wave.  This can sometimes but not always lead to VT especially in people with Long QT.  In a healthy heart it may not be a concern especially if you do get VT and it converts quickly on its own.  If you have LongQT you should avoid caffeine and cold/allergy medicines.  You should discuss this with your doctor to find out what it means for your particular situation.  Take care.
