What symptom does patent ductus arteriosus have

summary

The ductus arteriosus is located between the root of the innominate artery and the right pulmonary artery. The diastolic pressure of the peripheral artery decreases and the pulse pressure widens. This is due to the fact that during the diastolic period of the heart, the blood of the aorta is still shunted into the pulmonary artery and the blood flow of the systemic circulation decreases. What are the symptoms of patent ductus arteriosus.

What symptom does patent ductus arteriosus have

First: in the case of patent ductus arteriosus without complications, the aortic pressure is always higher than that of pulmonary artery in both systolic and diastolic periods, resulting in continuous left to right shunt at the level of pulmonary artery, continuous murmur and pulmonary congestion, which need attention!

Second: pulmonary hypertension and right ventricular hypertrophy are complications. When the patent ductus arteriosus is thick, shunt to the pulmonary artery with large blood volume can cause pulmonary arterial pressure increase, and finally lead to right ventricular hypertrophy, dilation, and even failure.

Third: sometimes the pulmonary blood flow increases due to the left to right shunt of patent ductus arteriosus, so the left atrial return blood increases correspondingly, the left ventricular volume load increases, and the left to right shunt reduces the systemic blood flow.

matters needing attention

Usually to avoid excessive fatigue, more to ensure adequate sleep. Keep a good mood and avoid being too nervous and depressed. But also to strengthen physical exercise, enhance the body's resistance.
