Question
A four-and-a-half-year-old child, during a recent medical visit for excessive phlegm, was found to have a heart murmur upon examination by the doctor. It was suggested to undergo an electrocardiogram, which revealed a sinus arrhythmia. The child did not show any discomfort. What additional detailed tests are needed? There are physiological and pathological types of irregular heartbeat; how can they be distinguished?
Answer
Given the child’s condition, it can be confirmed that they have a sinus arrhythmia. Considering the doctor’s discovery of a heart murmur during auscultation, it is recommended to undergo an echocardiogram to further clarify the possibility of valve insufficiency or congenital heart disease. Whether it is a physiological or pathological irregular heartbeat, diagnosis is necessary. These suggestions may be helpful to you; wishing you and your family health!
