Thanks for your question on HCM. In my opinion you are having GERD (gastroesophageal reflux disease) mostly. But because of your SVT (supra ventricular tachycardia) history, it is better to rule out cardiac cause first. So get done 1. ECG 2. 2 d echo To rule out cardiac cause. If both are negative then no need to worry much for cardiac cause. Your symptoms are more suggestive of GERD. 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 the symptoms like central chest pain and nausea. Along with drugs, you need following life style modifications for symptomatic relief. 1. Avoid hot spot and spicy food. 2. Avoid stress and tension. 3. Avoid large meals, instead take frequent small meals. 4. Go for walk after meals. 5. Keep 2-3 pillows under head in bed. Don t worry much, you will be alright.
