history of rvot vt and am 18 year old female

Hello,
Welcome to the ehealthforum and I am glad to help you. RVOT-VT is one of the benign conditions and seen commonly in the young people. Normally, it does not result in a decompensation.

However, there’s a lways a small risk of dangerous arrhythmias like ventricular fibrillation. You are likely having extrasystoles (ectopic beats) resulting in the feeling of the missed beat.

I’ll suggest talking to your cardiologist and an electrophysiological study and going in for the radio-frequency ablation should help. I sincerely hope that helps. Take care.
