I ve had rapid heart beat for months now, around 100 or a bit above, I am 38 and most of my blood tests were normal, any idea what may be the cause?

Most were normal?: So what tests were out of range? A high thyroid level might cause your heart rate to accelerate. Being anemic (low red blood cell count or low hematocrit) may result in an increased heart rate, as your heart beats faster to try to circulate more oxygen to your cells. Anxiety can increase your heart rate. Btw, I'm assuming that your heart is normal, but it would be reasonable to get that checked! ...Read more

Symptoms of dehydration coupled with the normal sympathetic stress of activity could explain this--but if you are still symptomatic after assuring adequate hydration you should see a cardiologist for monitoring/echo-stress study. ...Read more

Can zyrtek cause behavioral changes, and rapid heart beat in children? Evaluating whether to give this to my son for dust mite allergy

Can zyrtek cause behavioral changes, and rapid heart beat in children? Evaluating whether to give this to my son for dust mite allergy

My family has experienced this first hand....so behavioral changes is certainly possible I expect. Talk to your allergist. ...Read more
