I am a 39 year old female .......my symptoms started about 3 weeks ago......i was asleep and i woke up about 1 am to a pounding heart ...heart was beating fast and hard ....i took my pulse and it was 160 per minute took my blood pressure and it was 170/110....felt dizzy cold sweats ....and a feeling of impending doom.....i called 911 and they said i was probably having a anxiety attack .....but i use to have those years ago and i know what they feel like ....this happens on and off mainly when i am asleep and i awaken to it or when i wake up in morning .......but mainly at night ....my doctor took blood test and all cardiac enzymes are normal and i was on a holter monitor for a week and they said all is well.... so they slap me on klonpin and tell me they will see me in a month.....i am scared ..i don't know what is happening to me ......and during the day time i have palpitations of heart ......if u have any answers please let me know i am very scared that my doctor and doctors are missing something......
