How long do you have to wait after svt ablation to have sex?

No restrictions : Other than care for venous puncture site...1-3 days.

Go for it: Generally speaking, if the ablation worked, it worked. Sexual activity is no better or worse than any other activity for your heart and if you go back into abnormal rhythm, you would have soon anyway. Just wait a couple of days after your procedure before engaging any activity which puts strain on the groin to avoid bleeding or oozing at the puncture sites where the sheaths were inserted. Enjoy!
