What type of doctor to see for heart palpations?

For several months I’ve felt my heart skipped beats and feel irregular as if I could feel my heart beating through my chest. I guess it is called a heart palpation. I’ve ready online normally they are not serious so I didn’t think anything of it.

A couple months ago I felt shortness of breath, sweat, light headed, and the palpation. I didn’t think it was serious so I just ignored it.

It was the only time I felt shortness of breath, sweating, light headed accompanied by the palpation. But just yesterday I found out about a young boy of 19 that had died of cardiac arrest from Wolf-Perkinson Disease. It had to do with irregular heart symptoms. I researched serious possibilities of heart palpations and apparently I should’ve called 911 when I felt the palpation, light headed, sweat, etc.

Now I’m paranoid that it’s something serious. I don’t feel it every day. Sometimes every other day…most of the time it is when I eat or when I’m worried.

Should I see a family doctor or a heart specialist?
