摘要:

The stethograph is an air-filled tube strapped to the chest. It was popular in the early part of the century as a means of detecting rib cage motion. When a second stethograph is strapped to the abdomen and coupled to an x-y recorder, a ‘loop’ is generated which characterizes the thoracoabdominal motion during inspiration. Inspiratory muscle weakness or dysynchrony can be reliably and economically evaluated with this technique. Visualizing thoracoabdominal motion on an x-y recorder provides a useful means of instructing patients during breathing retrain

A 30-year-old woman with livedo reticularis, central retinal vein thrombosis, vascular purpura and primary pulmonary hypertension is described. It seems that these findings were not a result of a mere coincidence and that at least in some of the patients, primary pulmonary hypertension may be a part of a generalized angiopathic process.
