Does patent ductus arteriosus affect heart rate

summary

Generally speaking, patients with congenital heart disease will have the clinical manifestations of patent ductus arteriosus, and it will also have a certain impact on the normal life of patients, as well as other tissues and organs. Let's talk about the effect of patent ductus arteriosus on heart rate.

Does patent ductus arteriosus affect heart rate

First, the ductus arteriosus was originally the normal blood flow channel between the pulmonary artery and the aorta during the fetal period. Due to the pulmonary respiratory dysfunction, the pulmonary artery blood from the right ventricle enters the descending aorta through the ductus arteriosus, while the blood from the left ventricle enters the ascending aorta, so the ductus arteriosus is necessary for the special circulation mode during the embryonic period. After birth, the lung swells and takes on the function of gas exchange. The pulmonary circulation and systemic circulation perform their respective functions. Soon after, the catheter is self closed due to disuse.

Second: if the continuous non closure and the formation of patent ductus arteriosus. Surgery should be performed to interrupt the blood flow. Patent ductus arteriosus (PDA) is a common congenital cardiovascular malformation, which accounts for about twice of the total number of congenital heart diseases in women than in men. The clinical manifestation of patent ductus arteriosus mainly depends on the amount of shunt blood from aorta to pulmonary artery, whether secondary pulmonary hypertension occurs and its degree.

Third: mild may have no obvious symptoms, severe may have heart failure. The common symptoms are palpitation, shortness of breath, fatigue, respiratory tract infection and growth retardation. Late pulmonary hypertension is severe, and cyanosis of the lower body may occur when reverse shunt occurs. During the physical examination of patent ductus arteriosus, the typical sign is a loud continuous machine like murmur, accompanied by tremor, heard between the left edge of sternum and the  rib.

matters needing attention

The regulation of heart rate depends on the sinus node, heart rate of patients with heart disease will always fluctuate. So when patients with patent ductus arteriosus, it will certainly have a certain impact on heart rate. It is suggested that patients should take proper exercise and eat reasonably.
