I have had 4 EKGs , holter monitor , and echocardiogram. All came back normal. Holter showed some palpitations but Dr said they were not worrisome. I am still feeling dizzy off and on, and palpitations (mostly at night when trying to fall asleep). I thought I would feel amazing if the tests all came back ok, but I still cannot shake the feeling something is really wrong. I don't know why I am still having palpitations, it is freaking me out. Can palpitations really be ok? I keep thinking that palpitations mean I have something wrong with my heart. I am so exhausted from all of this, this has been the worst month of my life.
