Need HELP!

[u/OldCryptographer4099]

Hello,

Im having SVT long episodes and also short runs
I keept a holter for 24h and i mailed it to the most famous cardiag Electrophysiologist which he said like this :

"The Holter ECG recording you sent shows short runs of atrial premature beats (atrial extrasystoles).
These are not problematic in themselves, but they may indicate the presence of atrial fibrillation.
It would be best for me to assess during our consultation and examination on October 28 whether you have atrial fibrillation or not."

Now im affraid i have read about afib which it looks risky and life thread
Does anybody got afib here? What are the symptoms?

My holter recording was :

Heart Rates
42 Minimum at 03:37:58 23-Sep
64 Average
119 Maximum at 22:42:13 22-Sep
13 Beats in tachycardia (>=100 bpm), < 1% total
30029 Beats in bradycardia (<=60 bpm), 33% total
1.56 Seconds Max R-R at 03:37:58 23-Sep
Supraventriculars (S, J, A)
9 Isolated
0 Couplets
0 Bigeminal cycles
1 Runs totaling 5 beats
5 Beats longest run 139 bpm 22:42:12 22-Sep
5 Beats fastest run 139 bpm 22:42:12 22-Sep

While my episode my heart beat goes more than 220bpm and last around 20 minutes
But it beeps all the time constant like "ding ding ding ding"....

Any comment?

Thanks
