Vasocardiogram

Vasocardiogram: what is it and how does it work

A vasocardiogram (VKG) is a test method that is used to evaluate the functioning of the cardiovascular system. This is a non-invasive procedure that measures changes in vascular tone and heart rate during exercise or at rest.

The name "vasocardiogram" comes from the words "vaso" (from the Latin "vaso", meaning "vessel") and "cardio" (from the Greek "kardia", meaning "heart"), as well as "gram" (from Greek "gramma", meaning "record"). Together these words describe the procedure for measuring and recording changes in blood vessels and the heart.

A vasocardiogram is performed using a special device called a vasocardiograph. A cuff is placed on the patient's wrist or lower leg, which inflates and compresses the blood vessels in a certain area of ​​the body. Blood pressure and pulse are then measured before and after the blood vessels are compressed.

The resulting measurements produce a graph that shows changes in blood pressure and heart rate over time. This graph is called a vasocardiogram. Doctors can use this information to analyze the state of the patient's cardiovascular system and identify problems with its functioning.

A vasocardiogram can be performed both at rest and during physical activity, for example, on an exercise bike or treadmill. During exercise, the heart works more intensely, which can help identify hidden problems in its functioning.

Although a vasocardiogram is considered a safe procedure, it may be contraindicated in some cases, such as severe chest pain, hypertension, or other cardiovascular conditions. Before undergoing this procedure, you should discuss all possible risks and contraindications with your doctor.

In general, a vasocardiogram is a useful tool for assessing the functioning of the cardiovascular system and identifying abnormalities in its functioning. This is a non-invasive procedure that can be performed either at rest or during physical activity. If you have any symptoms or risks related to the cardiovascular system, do not hesitate to consult a doctor for this procedure.

Vasocardiography The vasocardiographic picture at rest represents pronounced changes associated with the constant conduction of the physiological rhythm of the heart through the dilated aortic valve and the internal jugular vein.
