What are the symptoms of heart palpitations?

Question
Hello doctor,
I have a heart disease, my heart beats faster than normal people. At that time, I was treated, when I was 18-19 years old, it recurred. From time to time, when I sit normally, my heart beats fast even though there is no activity or fear at all, it beats continuously for about half a day, it stops, maybe 2-3 times a week. Recently, I stood up and walked for a while, then my head was dizzy, I fell down and sat down, it was like a loss of feeling, I couldn't control it after about 10 seconds, it was over. So the doctor told me the symptoms of heart palpitations are signs of disease? I thank you doctor.
