question: Hi doctor, My dad recently was admitted to hospital after a heart attack, and he was in the hospital for almost a week. Currently, he was discharged and taking rest at home. The doctor advised that his heart pumping rate is around 23% and require improvement. Since morning he has been having hiccups, and he is burping a lot. I would like your help to review the results and also let me know if hiccups and burping are to be worried. Please suggest anything that needs to be done from our end. I appreciate your response.
