Fast pulse - after heart attack?

I am a 29-year-old female and had a heart attack in March. My pulse rate is still very fast. I was put on a beta-blocker to counteract this. Can you tell me should I be doing something else as well?

You say that your heart rate is still quite fast even though you are on a beta-blocker, which suggests to me that, perhaps the drug dosage that you are currently receiving needs to be adjusted. Beta-blockers are used to slow the heart rate thereby preventing the onset of strain, which could be triggered by an excessively fast heart rate. It is customary when prescribing beta-blockers to check the heart rate from time to time to ensure that adequate beta blockade has been achieved. In that situation if the resting pulse rate is still quite fast then it is customary to increase the dose of beta-blocker. I would suggest that you re-visit your GP and have your heart rate checked and if necessary have the dose of medication adjusted.
