Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are not having any heart diseases. R wave in ecg is normal. This wave is normally present in ecg. So no need to worry for heart diseases.
And at your age of 20 years, heart diseases are unlikely.
Your all symptoms are more suggestive of GERD (
gastroesophageal reflux disease).
It is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the
esophagus and cause symptoms of
chest pain, gaseous distention,
flatulence etc.
So avoid stress and tension. Avoid hot and spicy food. Take
pantoprazole and pro kinetic drug (levosulperide). Quit smoking and Alcohol if you have these habits.
Keep 2-3 pillows under head in bed to prevent reflux.
Don't worry, with all these, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
