title: [Relationship between the curve of the instantaneous pressure gradients and the enveloping heart sound].
abstract: The curve of instantaneous pressure gradients between the communicating chambers of the heart represents the "enveloping" one of the cardiac sounds. This curve is proportional to the curve of the instantaneous rates of the blood flow in the given area of the system. Consequently, the higher the pressure gradient, the greater the rate of the blood flow and the greater the oscillation range on the phonocardiogram.
