Heather, if your cardiologist is making you go through that many tests, the doctor must think that the heart rate is abnormal.

My oldest sister has a resting heart rate of 100. She has a mitral heart valve defect. She doesn't exercise, so I can't tell you what her aerobic heart rate is.

My resting heart rate is in the 50s to low 60s. That is a huge contrast between me and my sister in the numbers.

Please follow up to this thread with the results of the medical tests. Perhaps the cardiologist will decide the numbers you get are normal for you. If not, if there is a problem, it is a good thing you find it now.
