Hello Good Morning,
Do not take any chest pain in easier way, it can be related to heart.
You are giving history of chronic chest pain
, that might be a gastritis
reasons also, but you have no relief by medications, and you are a known hypertensive patient, so you should be careful towards your heart.
ECG is just a screening test of the heart, it does not represent the all the actual status of the heart, means ECG can be of normal limits even there can be presence of some cardiac issues.
So you should go for following steps:
1. UGI Endoscopy to know the status of your Gastritis or duodenal ulcers.
2. BP needs to be maintained, consult to GP to revise your medications.
3. Lipid Profile
for your cholesterol
4. Repeat ECG once again.
5. 2D-ECHO cardiogram for actual status of the heart.
6. If needed, then go for cardiac angiography
