Hello! Thank you for asking on HCM! I understand your concern and would like to explain that your symptoms seem to be related to anxiety and dyspepsia. These two disorders would explain the burping after eating two. All your cardiac tests have resulted normal, and based also on the nature of your complains, I would exclude any cardiac disorders related to your symptomatology. I recommend performing a fibrogastroscopy to rule out any gastroesophageal reflux, or esophageal spasms. Regarding Paxil therapy, I recommend waiting some days (up to two weeks) to show its complete effects. This is a low starting dose and higher doses may be needed. I am sure that your symptoms will go away spontaneously. I also recommend eating in small meals during the day and avoid caffeine intake or energy supplements. Hope to have been of help! Best regards, Dr. Iliri
