Lead Vf

Recently, increasing attention has been paid to the Vf lead in electrocardiography. This lead is used to record the electrical activity of the heart that occurs during ventricular contraction.

Lead Vf represents the potential difference between two electrodes that are located on the patient's left and right arms. In this case, the active electrode is on the left hand, and the passive electrode is on the right hand.

This lead allows you to obtain information about the contraction of the ventricles of the heart and identify possible disturbances in the functioning of the heart. It can be used to diagnose various diseases, such as myocardial infarction, arrhythmias, impulse conduction blockade and others.

However, when using the Vf lead, some considerations must be taken into account. For example, the active electrode should be located at least 10 cm from the passive electrode to avoid signal distortion. In addition, before starting the study, you must ensure that the electrodes are correctly connected to the ECG machine.

In general, the Vf lead is an important method of electrocardiographic research, which allows one to obtain more complete information about the functioning of the heart and the diagnosis of various diseases.

Lead VF (V) refers to a 6-lead ECG recording where the active electrode is placed on the right leg (not the left hip, as erroneously stated in another article), and one or more passive electrodes are placed on the body between the chest and hips, left and right. There is nothing wrong with Vf lead - this term is well established in the professional literature.

This type of ECG lead is important because the heart rhythm is often destabilized during prolonged physical activity of the patient. Lead V helps examine pathological changes occurring in the heart muscle to determine the cause of the disease.
