The resting hyperventilation of congenital heart disease.

Resting hyperventilation in adults with atrial septal defect.

Pulmonary functions may be considerably influenced by changes in pulmonary haemodynamics in congenital heart disease. In analysing this problem we have found resting hyperventilation to be a common finding in these patients. There are few published studies on this relation and those that exist do not agree. In the present study the resting hyperventilation has been related to the pulmonary circ...

Hyperventilation test for diagnosis of left-to-right circulatory shunts.

Pulmonary and systemic arterial carbon dioxide tensions (Pco2) were measured at cardiac catheterization in I.f patients with left-to-right circulatory shunts and in irS patients with valvular heart disease. The measurements were performed under resting conditions and at 5-sec intervals during a 30-sec period of hyperventilation. In both groups the systemic arterial Pco2 fell significantly durin...

The Rate of Addiction in Parents of Children with Congenital Heart Disease Compared with Healthy Children

BackgroundCongenital heart diseases (CHD) are the most common congenital anomaly in children and also the leading cause of mortality from congenital anomalies. Various factors including smoking, drinking alcohol and addiction play role in development of congenital heart diseases. This study was conducted with the aim of investigation of the prevalence of addiction in parents of children with co...
