Should I be concerned about my heart rate and heart palpitation feeling?

I'll try to make a long story short! I had my gall bladder removed in October and have to be careful what I eat b/c it can cause me to have indigestion or upset my stomach. For the past couple of months it's happened sporadically like maybe five different mornings I've woken up anytime btw. 1:30-5:30 am with a pounding heart, sweating, and a feeling of indigestion or upset stomach. I know what is causing it b/c it always seems to happen after I have eatten something like Barbeque or something greasy. One morning a few weeks ago it happened and I got up and actually threw up. It happened this morning and I felt hot and my heart was pounding so for curiosity I got up and used my husbands blood pressure machine. I don't know how accurate this machine is but it scared me b/c my bp was 133/74 and heart rate was 110. I took a Zantac 75 which knocked out the indigestion feeling but my heart rate being that high scared me. I am a 25 yr old female. 5 ft tall 118 lbs and in good shape. Have always had good bp (133/74 is high for me). I don't drink alcohol or smoke and I am a runner so I am in shape. Sorry this is so long but should I be concerned?
