Hi Jade,
Have you had a tilt table test? the utility of this test is sometimes debated, but it can be useful for people with postural tachycardia symptoms. As an example, I saw a 20 year old college student that passed out in class. She had a normal EKG, Holter, event monitor, and echo. We put her on an upright tilt table test and very early in the test her blood pressure dropped and she had a 10 second sinus pause leading to syncope (passing out). This is what I would do next.
If this is normal, anxiety is certainly a possibility and I would consider an SSRI like effexor, paxil, prozac, zoloft, etc. to see if it helps. I would even consider this if your tilt table is positive as anxiety goes hand in hand with postural tachycardia syndromes.
I hope this helps answer your question. Good luck.
somehow I have same symptoms, sometimes i feel dizzy but when i check my pulse it is normal as always for example it is 60 or little more or less.but sometimes it beats faster till 90-100 without any activity, at this period of beats i feel something happens in my chest, it is not pain or ? and after a short time (1 or 2 secs)i feel a heavy pulse and after that every thing goes ok but some anxiety.If casually through this event I check my pulse I feel an interrupt or skipping pulse.It makes me crazy.Also sometimes i feel pain in my chest bones dr.s siad they are due to ur anxiety.
I did echo which was ok and 24 hrs holter i had a period of 43 bpm during sleep at night and a 2.14 secs rest in hearts beat plus 2 rests less than 2 secs.
whats going on me? what are skips in my heart with odd feeling?
