What is cause of a sudden change in heart rhythm, which can be felt or can say a shock that lasts about 2 to 4 seconds after this i feel like lightness or air my heart ,i have experienced it for almost years, but it's not frequent , it happens 1 to 2 times a week or in 2 to 3 months. Is it due to any
vitamin or minerals deficiency ? now i also have a leprosy treatment and have light diarrhea issues too due to medication side effects.
I think it's because of the sudden low blood pressure, but it is back to normal soon .. but I don't know exactly , so what is the exact cause of this condition ?
