ECG and ECO test and blood test.

Hello Sir, On Friday, since afternoon I was feeling pain in my stomach and pain was radiating on the left side of my stomach and moving to my chest also. I had digene and eno but didn't get any relief. It was sometime very much and sometimes very little pain. In the evening I was walking and suddenly I felt restlessness and light headed started sweating heavily and for sometime there was a blackout and there was a vomiting sensation, So I lay down on the ground. Then after 2-3 minutes and then I got up I had a vomit which was only water. Then I went to the hospital, they did ECG, eco, some blood tests and when I reached the hospital my BP was 110/71. They suspected appendicitis. Next day I consulted with the physician and she said everything is fine and she also suspected the same and asked me to consult a surgeon. I wanted to know what happens to me and I see there are some abnormalities in ECG. kindly evaluate and let me know if anything is not proper. PFA reports Thanks.
