[Phonocardiogram characteristics in different forms of pulmonary hypertension].
To study the peculiarities of phonocardiogrammes in pulmonary hypertension of different genesis a comparison was conducted between the phonocardiographic data and those of heart catheterization and zonotomography. The study was conducted in 49 normal individuals and 177 patients with various lesions accompanied by an elevated pressure in the pulmonary vessels. It was found that no phonocardiographic peculiarities inherent in pulmonary hypertension are typical for any of the examined entities. The common features of pulmonary hypertension are: 1) growing amplitude of the pulmonary component of the II sound, increasing parallel to the degree of hypertension (with the exception of patients with chronic non-specific pulmonary lesions in whom the pulmonary component of the II sound does not grow, in absolute figures); 2) reduction of the coefficient II/IIIP of the II sound components, also developing parallel to the growth of hypertension; 3) detection of the ejection sound on the phonocardiogramme, as well as of a systolic murmur of the ejection and of a diastolic murmur; 4) increasing indices of the IV sound recordings in primary vascular hypertension. Not infrequently the amplitude of the Isound is also increased in cases of pulmonary hypertension, although its direct relationship with pulmonary hypertension is hardly possible.
