Thanks for your question on Healthcare Magic.
I can understand your concern.
No need to worry for heart diseases as your ecg is non significant.
Since you are having GERD (
gastroesophageal reflux disease), this can also cause intermittent
chest pain.
You are improving with
antacid (
ranitidine) but pain appeared when it's effect decline.
So, we should treat your GERD to relieve your chest pain.
You should follow these steps for better symptomatic relief in GERD.
1. Avoid stress and tension, be relax and calm.
2. Avoid hot and spicy food. Avoid junk food.
3. Avoid large meals, instead take frequent small meals.
4. Take
pantoprazole tablet on empty stomach. This is better then ranitidine.
5. Keep 2-3 pillows under head in bed to prevent reflux and pain.
6. Quit smoking and Alcohol if you have these habits.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
