Supraventricular Tachycardia (PSVT) and Running

Welcome to Mayo Connect - I do have a recommendation, if you have a cardiologist this is a question for them. If you do not, you probably should consult one before you undertake your first marathon.
There can be a number of causes for SVT, and exercise is still an excellent idea when you have it. A marathon (especially a first time) is not "exercise" - it is a great stressor of your body. Changes such as pushing yourself, electrolyte changes due to long distance running, possible dehydration, fatigue, etc could bring on an episode - which might bring you down in a crowd.
My recommendation is that you get cleared by a cardiologist before you try a marathon.

Hi Sue
Thanks for the recommendation, but I have a follow-up question. I am an avid runner and have about 13 marathons under my belt so far. I am in the process of getting checked out what causes my palpitations, which seem to come and go unrelated to my training. (currently carrying a heart for 14 days and scheduled for an MRI). My issue with my cardiologist is that he, in general, doesn't understand running at this level (I did a treadmill test, which was a breeze), and I would like to find a solution that allows me to continue as long as possible without limiting me in the sport I love. I understand that safety comes first, but trying to educate myself as much as possible so I can ask the right questions at my next consultation. the results of my last holter (14 days in dec) was as follow :
1) Sinus rhythm with the average heart rate of 51 bpm (min 31, max 142 bpm), 52% of bradycardia.
2) Occasional ventricular premature beats - 388 isolated, 2 couplets and 5 runs of nonsustained ventricular tachycardia - longest 12 beats long @ 150 bpm and fastest 6 @ 187 bpm.
3) Rare supraventricular premature beats - 8 isolated and 4 runs of atrial tachycardia - longest 6 beats and fastest
4 @ 124 bpm.
4) There are 77 episodes of long R-R intervals due to sinus pauses, 17 of them are (> 3 seconds) and the longest pause lasted for 3.71 seconds @ 8:29pm.
5) The patient reported symptoms of palpitation, correspond with sinus rhythm/bradycardia, one of them right after a short run of ventricular tachycardia.
