I have been going to the Dr for several years trying to get to the bottom of this. My Dr has been very patient but has ran out of options. I am 61 years old, but this problem has become more prevalent in recent years. I seem to be able to do most any physical activity, including jogging, but 6 to 8 hours later I start getting heart palpitations and nausea. The severity depends on the amount of activity. The palpitations usually lessen in severity within several hours and then I start getting burning in the left chest. Sometimes I get pressure in my left ear and burning in the left side of my neck. I have had a stress test, echo and heart catherization. Also, cat scan of the upper chest and most if not all of the blood work. I have been walking 30 minutes every day, but if I miss a day or two and begin again, the palpitations come with it. I never know where the threshold of activity is to start these palpitations. I never get a racing heart of shortness of breath. I try to stay hydrated also by drinking water.

I have also worn a heart monitor and nothing was noted.

I have since found that my 28 year old daughter has very similiar conditions, but here threshold is much higher.

Does anyone else have delayed palpitations and nausea? What was your diagnosis?
