My doc and I have had a relationship for over 10 years and I value her advice.....most of the time. For a variety of reasons, this last physical seemed rushed and she ordered a few tests for me..........one of them being a stress test. I'm 67, female, am on a drug for hi bld pressure....under control, weight under control, I exercise in a gym 3x a week, told her about palpations once maybe every 3 mos, live a 'peaceful' retired life...... What 'markers' does a doctor refer to before ordering a stress test?
