Phonocardiogram (top) and flebogamma (bottom) healthy man: I and II - the first and second colours.

Flebogamma curve, reflecting fluctuations of the venous wall, connected with the activity of the heart (curve venous pulse). Record flebogamma carried out in a lying position of the patient by a special sensor, which impose on the region jugular vein right (above the collarbone close to the outer edge of sternocleidomastoid muscle). Normal flebogamma consists of several waves, reflecting the contraction of the right atrium and the right ventricle (see figure). The size and shape of waves flebogamma change with the vices of the tricuspid valve, the narrowing of the pulmonary trunk, the pressure in the pulmonary circulation and other
