Patient: Description (time of onset, main symptoms, hospital visited, etc.): The doctor heard a heart murmur when the child was one month old, but an ultrasound of the heart showed no abnormality, but the doctor said there was still a heart murmur at the three-month vaccination. What should I do? Anhui Provincial Children’s Hospital, Department of Cardiology, Jiang Rong: A murmur is not the same as heart disease, many normal people have a little physiological murmur, but it does not have any effect on the human body. Since there is no problem with the heart ultrasound, there is usually no problem, so don’t worry too much. Anhui Children’s Hospital, Department of Cardiology Jiang Rong Patient: Thank you!
