25 years male,162 cm,60kg/151lbs,very little exercise,sleeping habits not so good(though a heavy sleeper and sleep twice in 24 hour,one 6-7 hour at night and 1-2 hour at noon)). Never experienced something like this before.On 24/02/2021 in the evening I was at the station carrying two heavy bags and wearing a N 95 mask ( a little suffocated).After putting the bags down I went to buy some snacks(after 10-15 minutes of rest) and all of a sudden I started having this rapid rates or palpitations in my heart and it lasted about a minute or so......also there was sweating on my palms feets and forehead.Next day I went to the doctor did and ecg and he said everything in fine,just take rest.Then on 1/03/2021 in the morning around 10 am my heart was beating very fast again,I plugged the pulse oximeter it jumped from 80-85 to 144 beats....i was rushed to the hospital...again did ecg and was told nothing to worry.They asked for couple of tests which i did.Following tests---- Echocardiogram(usg of heart),Thyroid test,complete hemogram,vitamin D,serum creatinine......Everything showed normal except vitamin D was little insufficient.He prescribed me beta blocker and vitamin D and asked to maintain healthy lifestyle.After two days in the noon I was having same symptoms and was taken to a cardiologist ,he did the ecg and found irregularity in the rates.He prescribed me AMIODARONE 200 mg and Bisoprolol Fumarate 2.5 mg.Since last palpitation its not stopping and happening after 15-20 minutes.Its more while I am in rest or laying down...with exercise or walking it decreases a little bu again when I am sitting after exercise or walking its increasing .Doctor said its normal and eventually with healthy lifestyle it will go away.My doubts are following
1.Is it normal/common at all?
2.Is it reversible with medicine or do i need electrical shock therapy?
3.In future(after a month or so) if i discontinue medicine,what are my chances of dying/very high pulse rate jumps?
4.Why didn't any cardiologist prescribed angiogram?Is it bcoz of my age or normal Echocardiogram(usg)?(i doubt they would do it after a stroke or heart attack...gosh!!)
5.I do feel pain in my left arm sometimes and low in energy with little dizzy head sometimes...am I having mini heart attacks and mini strokes?
6.Now I get easily tired after a walk
7.can somebody join gym and stuff after this sort of stuff?
8.not sure if I ever return to normal?
..........while writing this I had palpitations many times.....peace.Please reply me if you went through the same.
