I noticed my heart rate would go higher than my husbands, once heart rate hit 130 I would get a tightness, squeezing, pressure in my chest
. Once I stop and get the heart rate below 125, the tightness
goes away. I tried working thru it and heart rate went up to over 180. This has happened when I have been under SEVERE stress also. Went to family doctor, he had me do a nuclear stress test, it was normal. Doctor sent me to Cardiologist who said I needed a heart cath.
