Should I be scared?

For a couple months now I’ve been dealing with constant heart palpitations. I’ve gone to the dr for it many times which isn’t any help at all he dismissed several times. It comes randomly with no warning weather I’m standing, walking , laying down , sitting. I am not pregnant !!! They last a couple seconds and then go away but are super consistent. I’m not stressed nor have anxiety I just want this figured out but my drs are no help!
