Ecg attached. From gastrologist then?

You are city I was travelling on train when I suddenly started feeling very anxious, severe chest pain in Central Part and I got off the train to emergency.. they did ecg which was normal except fast rate but my bp was too high- 180/110.. I was Given medication to control it and after some rest discharged...Today morning again I felt uneasiness n chest pain n went for ecg which I have attached. Today my bp is 110/80... I am feeling scared if the high BP did some damage? In this ecg qtc is 454 n normal is 440,, is this causing symptoms? Plz note my heart tests done some months back like echo, tmt, lipids all was gud Shall I now see consultation from gastrologist then? As I am also having bloating n past history of stress induced reflux
