Hello doctor! Recently, I have symptoms of light, shallow breathing, sometimes I don't want to breathe, coughing, wheezing, like lack of air, chest tightness every time I take a deep breath. I went to the doctor but the doctor said it was because of the heart, but the echocardiogram showed that the heart was normal, there was no disease.

Hi doctor. I often have chest pain, move around a lot, feel short of breath, dizzy. Sometimes when people are weak and sweaty, please tell me if there are symptoms of chest pain, shortness of breath with dizziness and sweating, is there a heart problem and does it have any effect?
