My heart...

Do anyone know anything about having a irregular heartbeat?
Coz I am having a problem with that now. (since a mth ago)
Can it be my eating habit? or my sleeping pattern? or......

Out of the blue, my heart seem to be pumping extra hard.
When i am watching tv, reading a book or even taking a shower!..
U get the point...

People are passing away in their sleep nowadays.
There's another one who a lady just 41 yr old!
This no longer only happen to old people.
This do worry me a bit...

And yes. I am very kaisei
