I (f,30) get tachycardia when I try to go to sleep. It's not really bad, just a pulse of 100bpm and normal blodd pressure (110/65). When I sit up again, the pulse goes back to normal (75) after a couple of minutes.
I don't really feel bad and apart from the rapid heart beat that keeps me from sleeping (until it eventually drops below 90) I don't have any other symptoms.
I was treated for hypothyroidism for the past four years, but stopped at around the time when the tachycardia started. I went to see my doctor and hyperthyoroidism has been ruled out and my thyroid gland seems fine without medication, so the doctor told me I could stay off the medication.
I feel great, actually I feel much better than I have ever felt - weird symptom isn't it ;-)
Any idea what could cause the rapid heart beat - could it just be from lying down?
Thanx so much for your help!!!!
PS: I started a high dose B6 treatment for muscle problems - made the symptoms disappear, but could B6 cause tachycardia?
