Detailed Answer:
Hi,
Thanks for writing your query.

After reading your post, I would like to advise that you should get yourself clinically examined and investigated. Your symptoms can be due to anxiety but a thorough clinical evaluation will help.

Following investigations may be helpful :-
1. Hemoglobin levels.
2. ECG.
3. 2D Echo of heart.
4. Thyroid profile.
5. Blood pressure and heart rate monitoring.

More can be commented after knowing the reports of the above mentioned investigations and according to the clinical evaluation done by your doctor.

I hope this is helpful to you.
If you have any further query, I will be happy to help.
Thanks.

My brother is having a heart cath tomorrow. Apparently he has had a heart attack sometime in the last ten years.

His heart rate has become uncontrollable with meds and sontinues to beat at 131. He said the doctor told him some rate (he couldn't remember) was at 25 and should be higher. Can you perhaps clarify what this may mean?
