Question

During the 42-day check-up, a newborn was found to have a heart murmur, accompanied by symptoms such as rapid breathing, restlessness, sweating, and blue complexion. The baby also has difficulty breastfeeding and is prone to choking. What could be the possible causes?

Answer

Newborn heart murmurs may be physiological, usually soft and without affecting health. However, if accompanied by other symptoms, they may be pathological and require a cardiac ultrasound to rule out conditions. If the murmur is physiological, no treatment is necessary; if it is pathological, it may be a sign of congenital heart disease and further examination and treatment are needed.
