Thanks for your question on Health Care Magic.
I can understand your concern.
No need to worry for heart diseases because your ecg is normal.
Sometimes
gastritis and GERD (
gastroesophageal reflux disease) can cause similar symptoms.
If you are having stress and
anxiety then both of these actually further worsen the symptoms.
So avoid stress and tension, be relax and calm.
For control of GERD do following things.
Avoid hot and spicy food. Avoid junk food.
Avoid large meals, instead take frequent small meals.
Take
proton pump inhibitors and prokinetic drugs.
Loose weight if you are obese. Quit
smoking and alcohol if you have these habits.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
