Il en résulte que la quantité de sang pompée par le cœur est insuffisante. Médicalement, on décrit cela comme un faible débit cardiaque. Cette faiblesse du cœur entraîne une insuffisance en oxygène livré au corps. Cette condition porte le nom d’insuffisance cardiaque. Diagnosis usually involves detecting and recording changes in the baby's heart and body, and conducting various diagnostic tests.</p><h2>À retenir</h2> <ul><li>L’insuffisance cardiaque survient lorsque le muscle cardiaque est trop faible pour expulser suffisamment de sang, de telle sorte qu’on observe un manque d’oxygène dans le corps. </li> <li>La détection et l’enregistrement des changements dans le cœur et le corps du bébé aideront à poser un diagnostic d’insuffisance cardiaque.</li> <li>L’insuffisance cardiaque peut être causée ou aggravée par l’asphyxie, la persistance du canal artériel (PCA), la sepsie et l’hypoglycémie.</li> <li>Les tests réalisés afin de diagnostiquer l’insuffisance cardiaque comprennent un échocardiogramme, la mesure des taux de gaz sanguins, une analyse des leucocytes ainsi que des formules sanguines additionnelles pour investiguer d’autres déséquilibres métaboliques.</li></ul>

To compensate for this, the chambers of the heart become enlarged to increase the volume of blood each beat propels though the system.</figcaption> </figure> <p>Lacking oxygen, a baby’s body will try to compensate in various ways, including:</p><ul><li>The heart may beat faster and the baby’s blood pressure may be abnormally low.</li><li>The chambers of the heart may enlarge in an attempt to increase the volume of blood each beat propels though the system. This can be detected with X-rays and other imaging technology.</li><li>Blood flow may be directed to the vital organs at the expense of the extremities. If this is the case, heart beat pulses, which can be felt through the skin, will get progressively and significantly weaker moving from the body to the hands and feet. Additionally, blood flow to the skin will suffer. As a reduced amount of blood is reaching the capillaries near the skin, the pink tinge the blood gives the skin will also be reduced, which may make the baby seem pale.</li><li>Lack of oxygenated blood may trigger faster breathing, which can lead to respiratory distress.</li></ul><p>Detecting and recording these changes will help lead to a diagnosis of congestive heart failure.</p><h2>Other diagnostic tests</h2><p>Poor heart function leading to low cardiac output can be caused or further complicated by several other factors.
