[Characteristics of atrial mechanoreceptors and elastic properties of the atria in experimental cardiac failure].
Cats developed heart failure as a result of a partial stenosis operation of the pulmonary artery. Within 10 to 25 days after the operation, pressure in the right atrium was higher than normal and the atrium diameter was larger. The dependence of atrial distension and integral mechanoreceptor activity in the right atrium on atrial pressure was studied. A possible physiological significance of the change in atrial mechanoreceptor characteristics of animals with heart failure, was investigated.
