Review or opinion. Aneurysm problem?

Hi doctor I get repeated palpitations for last 8 months so I took complete blood test, stool test, Echo, ECG and finally Holter. PFA for Holter results for your opinion. Doctor checked all my reports and said everything is normal. My concern is repeated palpitations when I wakeup in the morning and anything I eat after 10 mints, i get discomfort in my stomach and l get palpitations. I can see palpitations in my stomach still  when I sleep. I see myself became thin as I am not able to eat spicy foods nor junk foods and oily food. Earlier I was 75 kg after 3 months i have reduced to 64 kg due to diet. So this has reduced my weight. seeing this i took all the tests reports. Now question is as doctor said all my blood tests are normal no need to go for ultrasound scan. Should I do it? What is the cause of this palpitations. Because of this i get negative thoughts. Even took endoscopy which came as Pangastristis. Please advise. or is it abdominal aortic aneurysm problem?
