Rheography Longitudinal

Longitudinal rheography

Longitudinal rheography is a type of limb rheography in which the electrodes are placed along its longitudinal axis.

This method allows you to evaluate the function of the blood vessels of the entire limb as a whole. It provides information about vascular tone, wall elasticity, and linear blood flow velocity.

For longitudinal rheography, 4 electrodes are used, which are fixed on the proximal and distal parts of the limb along its axis. The rheogram is recorded between the distal and proximal electrodes.

Thus, longitudinal rheography allows you to obtain a general picture of the state of blood circulation in the limb and identify blood flow disorders throughout its entire length. This method is widely used in clinical practice for diagnosing vascular diseases.

**Longitudinal rheography** is a method for studying the state of the cardiovascular system by recording pulse oscillations of the muscle walls.

The device itself is a monitor that has an ultrasonic sensor. Oscillations are displayed on the screen not only from one limb, but from both at once. During diagnosis, two flexible plates are placed on the ultrasound device and applied to the body.

When a muscle contracts under the influence of contraction, blood flows from the periphery and enters the arterial system, then into the pulmonary artery, the capillaries of the lungs, and from there back to the left side of the heart (conus pulmonary). The sensor records the bloodstream. The presence of pathology can be understood by deciphering the data: *normally, the strength and amplitude of the pulse wave increases closer to the heart; * in healthy people, as they age, their frequency decreases. If the curve increases, the patient has diseases of the arteries of the lower extremities. When the curve is high and changes, venous regulation is impaired. Gradual voltage reduction
