Was this heart rate of 60 immediately after exercise or several minutes later? Did you measure it with a heart rate monitor or with your own hand on your pulse?
If this is a few minutes after exercise this may not be that abnormal. While reassuring that you had a stress test 3 years ago which was normal, it sounds to me like you are having new symptoms and a heart rate is not going up as it should, an exercise stress test with an EKG only(NO NUCLEAR or ECHO imaging) would be a start to see exactly where the problem lies, if any, in the conduction system of the heart. Before doing so, I would make sure that the heart rate is accurately measured.
Doctor. I probably rested 7 minutes before I took my pulse/bp. I used a blood pressure cuff with heart rate.
My heart usually goes up when it should.
I think everything is fine, this is normal to have that heart rate several minutes after exercise.
Thank you so much for taking the time to answer my question. I really appreciate it.
