High hear rate or not?

[thomasb007]

Hi,

My heart rate in the morning is about 75 beats per minute. But as the day progresses, while I have my breakfast, or walk to office, it goes up to 100 or even 120 while walking.

While sittimg down it again goes to 100-95-90... 100... like that. Even walking makes it 110-120.

I am fat with a weight of 105 and 170 cms. I walk 2 km to work every day. Thats the only excercise I get.

I take fluxetine and beclamethasone. I have had anxiety attacks and generally I am very anxious person.

My psychiatrist says its just anxiety. But I dont understand, how can anxiety cause my heart rate to be high all day(except when I wake up). He also asked me to take beta blockers(nebuvilol) before I board a plane to keep my heart rate normal during flight. Why has prescribed me beta blockers(only to be taken before flight) if its just anxiety?

Im totally scared. I am in the fear of having a cardiac arrest or something like that.
I have seen a cardialogist and taken an echo-cardio gram, sound-echo, treadmill test, and was certified OK. I saw the cardiologist in the morning(when my heart rate was low). Would that make a difference? My Blood pressure is normal. No diabetis and boderline cholesterol.

I just can figure out why my heart rate goes to 100-110. I am scared to excercise because of this. What is wriong with me?

Any reason you're measuring your heart rate all the time?  Does that sound like something you did before you got anxious?  If you saw someone else doing that, would you think it was productive?
