Started with a little shock

I am on a beta blocker for svt, mine was ignored for years, like you by the time I got to A and E it was going down until the big long attack in February.  I have missed beats still but no svt, I had many small attacks before for years.

SVT is very unpredicable.  We never know when it will go off.  My episodes last from 10 minutes to 6 hours

if you have a cardiologist, ask them to put a 30 day event monitor on and see if it can be captured. Once I had where I felt something pop in my head before having SVT. 

I recently posted this somewhere here recently but you can buy a Polar chest strap for about $80 and capture all your heart beats on your phone and see any SVT attacks.  I even ran it all night one time and saw some attacks, but fortunately mine are individual episodes and the cardiologist explained in this case they don't recommend any additional treatment, other than I am on 50mg beta blocker. Polar even has a newer strap that fits arm or wrist.

Doctor never gave me any medicine for svt, acc to them medicines comes with side affects and abalation is best for this . However breathing yoga has permanent fix for this but it takes about 5-6 months and have to be practiced Everyday without fail. 

That "small current" could have been a jolt from stress hormones (adrenaline, etc.).  I've experienced something like that many times with SVT onset.  Most published info tells us that an otherwise healthy heart tolerates SVT quite well, and risk of cardiac arrest is low.  Still, you, I, any many others are understandably frightened when our heart begins racing for no apparent reason.

I hope you'll be able to work well with your health-care people to find the best approach for you.  There may well be an actual cure (ablation?) in your future.  Please take the best of care of yourself.

Thanks everyone for pouring your experiences.... i was really scared and now i feel confident.... thanks again for calmind my mind and somehow i hate adrenaline now 😇😇
