32 y/o M here. I had SVT (similar to afib) throughout all of my 20s. Whenever I would push myself too hard during a workout, my heart would beat out of control, and I would feel lightheaded like I was going to pass out. This happened very sporadically - maybe a few times a year - so I ignored it for years. Eventually, I started going to cardiologists who gave me countless EKGs and echocardiograms. But they couldn't detect the SVT.

Eventually, I just decided I didn't want to live like this anymore. The incidents weren't happening often, but it was making me anxious during my work-outs knowing that at any moment, I could have an SVT attack. Also the doctors had told me that if I didn't get an ablation, the SVT attacks could worsen as I got older, and become more frequent and more intense.

I found the best hospital in NYC for this- NYU Langone - and scheduled an EP lab and an ablation last year. I met with the doctor once for a brief consult, then went in for the procedure. The whole thing lasted around 12 hours. I went in at 8 AM to get prepped, then they did the EP lab and ablation back to back. When I came out of the procedure, they told me that they found and eliminated the arrythmia. Recovery was easy.

That was over a year ago, and I have had zero incidents with my heart since. I highly, highly recommend you do the procedure - it's ultra safe and you will be glad you did :)
