2 months ago I had a double bypass and mitrol valve repair.   Had a stress test 1 and the cardio released me for rehab.  At the rehab consultation they noticed that my stress test was abnormal.  They would not let me start and sent me back to my cardio.  Now I am waitng for the appt. next week.  What could this mean?  I was looking forward to starting rehab and getting on with my life.  I am a 48 y.o. female.  Thank you for any input.

i am 21 weeks preg and had a visit with a perinatal clinic.where the dr detected a low ventricular rate of 50-60 bpm everything else being normal.He said its a fetal heart block.is he sure or can this be an assumption at this stage.Is there any possibility that my baby s heart rate can improve in the coming weeks and she doesnt have a heart block?I am really worried.They have asked me to come for a follow up US in 4 weeks.Please help

For months, my husband has had sternum pain with exertion or strong emotions. He just had an EKG that showed a dip at the inferior lateral T-wave. The doctor ordered an imaging stress test (cardiolite), but we have a $3500 deductible and the test is $2500, so we cancelled until we have more info. Our fear is we'll pay $2500 and the test will be inconclusive and/or lead to another expensive test, and then another. Should we just go for a heart catheterization to begin with?
