Ballistocardiogram Longitudinal

B. Prolonged: reflections of changes in the body caused by its movement through the vertical axis of movement. **Prolonged B.** reflects changes in time that occur during certain periods of movement (for example, muscle contraction when hitting the membrane and the gradual restoration of this force) and are recorded horizontally, from left to right, i.e. from the start to the end of the expansion. When using phase analysis, this view can also be applied to the **extended axial ECG (xECG)** or **waveform 5**. As is known, **prolonged axial ECG** includes recording of continuous cuts from the outer edge of the film for 30-9

In everyday life, we hear about various medical terms and concepts, but not all of them have a clear and understandable meaning. One of these terms is longitudinal ballistocardiogram. In this article we will look at this term and find out what it means and how it is used in medicine.

Ballistocardiogama

Introduction

Ballistocardiography is a method for studying the cardiovascular system, based on recording an electrocardiogram during movement of a person or animal. This method allows you to evaluate the work of the heart and large arteries under conditions of physical activity. One type of ballistocardiogram is longitudinal ballistocardiography, which studies the movement of the body along the vertical axis during active physical activity and subsequent rest.

Description

A longitudinal ballistocardiogram is a recording of an electrocardiogram obtained during active movement along the vertical axis of the body, for example, when climbing stairs or walking up a hill. During movement, the body loses gravitational alignment, causing pendulum-like movements of the body. In this case, a painful blow occurs - a sharp decrease in barometric pressure, accompanied by an increase in cardiac output and contraction of the vessels of the lower extremities.

Thus, longitudinal ballisticography can be used to assess the functioning of cardiovascular organs under conditions where the body is subjected to severe physical stress.

Longitudinal ballistocardiogram (BCG) is a diagnostic method for assessing the condition of the human myocardium and cardiovascular system.

The method is based on recording body movements (for example, breathing) using a sensitive sensor located in the chest area. At the moment the heart contracts, the diaphragmatic reflex moves, and the pressure inside the lungs, the volume of intracardiac fluid and the position of the heart in the chest change. The amplitude of oscillations reflects the force of cardiac muscle ejection at one time or another. With long-term recording, even small heartbeats can be detected as periodic fluctuations in physiological parameters, however, for reliable diagnosis it is necessary to record data over several minutes.

BP is an additional examination method for identifying valve damage, coronary heart disease, and abnormalities in the development of the cardiovascular and respiratory systems. When assessing the results of the BCG analysis, in addition to cardiac pathology, it is necessary to take into account the presence of a number of concomitant diseases, including: anemia, osteochondrosis, asthma, laryngitis, tuberculosis, pneumonia, arthritis, various neuroses, inflammatory and oncological diseases of bone and muscle tissue. Evaluation of BCG results can be carried out either manually or automatically. This method has low information content and also requires some diagnostic skills.
