Lead Vr

Lead Vr: Study of the heart using the Wilson electrocardiogram

In modern medicine, electrocardiography (ECG) is an integral tool for diagnosing and assessing cardiac activity. One of the ECG methods used in clinical practice is the Vr lead, which is based on the Wilson lead system.

Vr lead is a method of recording the electrical activity of the heart in which the active electrode is placed on the patient's right arm. This method uses the principle of a three-electrode system, where the right hand serves as the active electrode, while the left hand and left leg are passive electrodes.

Using the Vr lead allows you to obtain information about cardiac potentials in the vertical plane passing through the heart. This allows the direction and intensity of electrical impulses generated by the heart to be assessed in this plane.

The Vr lead can be useful in diagnosing various heart diseases. For example, it can help identify cardiac conduction abnormalities, arrhythmias, and coronary heart disease. This method can also be used to assess the effectiveness of treatment and monitor the patient’s condition.

Obtaining a Vr lead differs from standard ECG leads such as the Lyon, Einthoven, or Cabrera leads. The Vr lead can be especially useful when taking ECGs in patients with abnormal electrode placement or when additional information about the vertical component of the heart's electrical activity is needed.

In conclusion, Vr lead based on Wilson electrocardiogram is an important method in the field of electrocardiography. It provides information about the vertical component of the electrical activity of the heart, which can be useful for the diagnosis and evaluation of heart disease. Doctors and cardiologists can use this method in their practice to obtain additional information about cardiac activity and make appropriate medical decisions.

Importance of VR lead in electrocardiography

The VR lead is one of five electrocardiographic research methods that allows for a high-quality diagnosis of the electrical activity of the heart. This method is based on the work of two equivalent electrodes, each of which is located on the patient’s hand of the same name. The technique is very sensitive and allows you to detect disturbances in the electrical conductivity of the heart in the early stages of the disease.

How the VR method works

The study uses two electrodes placed on the patient’s limbs parallel to each other and perpendicular to the cardiac section. The active sensor (red), located on the right side of the body, records the electrical activity of the heart at the moment of contraction and relaxation. The second (green) electrode records general fluctuations in activity (breathing). The results are displayed on a chart.

Types and features of abduction

Based on the type of pathology, the test is done in the following ways:

* transesophageal diversion; * ECG according to the Sky; * fifth standard lead for horizontal position
