Hello. I am 20 years old and am from Lithuania. I have been having long periods of increased pulse and difficulty breathing for 6 months now. I also feel weird pressure in my head and have periods of memory loss when I forget what was I just saying or what I just heard. It gets worst before going to sleep and about 4am when I wake up from very fast pulse (160) and I am in panic for about one hour after that, I am able to sleep again. I feel hopeless every time it happens and think I will never feel healthy again. I can't do any exercise because my heart starts jumping. I waited for 3 months for cardiologist appointment and she tested me with Holter monitor. Today when she examined results, she refered me to 3rd level cardiologist. She said she sees arrythmia in the results and I think, if I heard right, periods of heart stopping??
Does anyone know what tests or diagnosis can I expect? The doctor did not tell me anyting and now I have to wait for other appointment for a month. I'm finding very worrying information online about tests where a needle needs to be inserted in the heart, for example, or illnesses like heart failure, which is very stressul. When I remember all this when my pulse is 160, I get petrified and think(and feel) my heart is going to stop. I called an ambulance for a few times but all they see is increased pulse and give me sedatives.
ps.: my family doctor prescribed me bromazepam few months ago when I didn't know I have some rythm disorder. Is it safe for me to take them?
