Shortness of breath + fainting spells

[izehoze]

I am 25 years old and female. Recently I experienced a fainting spell, I have never fainted before. In the last 4 months or so I had shortness of breath while was not doing any activities, like sitting in the kitchen talking with my mom, or having a walk, I was not walking quick at all... or while watching TV.
I had ploblems with my heart rhythm before, EKG was normal, and after pushing a little they hooked me up in a 24 hour EKG (in Hungary/Europe). I was 7 months pregnant at that time, and the test showed fast rhythms, around 170 per minute during the night was the highest. They told me it is related to the pregnancy, nothing to worry about. I do feel fast rhythms here and there, but never fainted before in my life.
Also I would like to mention that I suffer from severe migraines since the birth of my first child 5 years ago, and just before migraines my feet and hand swell up, and feel like my heart is beating faster then usual.
During my fainting episode a week ago I was duing my normal morning rutine, and when I went to the bathroom to fix my hair I suddenly had a heatwave, I was soaking in sweat within seconds and my heart wanted to jump out of my chest. Also I could not feel my legs from knee down and just wanted to get to my bed to sit down. I laid down for about 15 minutes, but overall was not feeling good. I went to the doctor, and did not do anyhting other then taking my blood pressure and told me to rest for the day. he also told me that if this continues often then I should see a cardiologist.
Do you think I should see a doctor now, my family doc ignored the fact that I'm having shortness of breath for a period of time?

I would go to a cardiologist right away...better to be safe than sorry. They can do the tests to make sure your heart is OK. At least a 24 hour monitor and ECHO with doppler.

I would get pre-syncope (which is right before fainting) and short of breath, and found out I had heart issues...I found out in May, and had a defibrillator put in on July 25th.

I don't have the information to answer that. To be cautious, yes, I would see a cardiologist.  There is probably nothing wrong with your heart but I cannot say that for sure without a history, physical and some testing.  Given your age and they way you describe the symptoms, it sounds like inappropriate sinus tachycardia and neurocardiogenic syncope.  Neither condition is dangerous but they are associated with the symptoms you describe.  It is not possible to say for sure without further testing.

I hope this helps.
