An acyanotic heart defect, also known as non-cyanotic heart defect, is a class of congenital heart defects. In these, blood is shunted (flows) from the left side of the heart to the right side of the heart due to a structural defect (hole) in the interventricular septum. People often retain normal levels of oxyhemoglobin saturation in systemic circulation. This term is outdated, because a person with an acyanotic heart defect may show cyanosis (turn blue due to insufficient oxygen in the blood).〔 == Signs and symptoms == *Shortness of breath *Congested cough *Diaphoresis *Fatigue *Frequent respiratory infections *Machine-like heart murmur *Tachycardia *Tachypnea *Respiratory distress *Mild cyanosis (in right sided heart failure) *Poor growth and development (from increased energy spent on breathing) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acyanotic heart defect」の詳細全文を読む スポンサード リンク
