Lead Avf

The AVF (anterior vena cava) lead is an electrocardiography technique that is used to diagnose heart disease. In this enhanced lead, electrodes are placed on the patient's left leg and chest.

When performing an AVF lead, the electrodes on the left leg are connected to the first lead of the electrocardiograph, and the electrodes on the chest are connected to the second lead. This allows you to obtain information about the work of the heart in real time.

The AVF lead makes it possible to detect cardiac arrhythmias such as arrhythmias and blockages. In addition, it helps to determine the presence of blockages in the heart and assess their degree.

One of the advantages of AVF lead is its high accuracy. Thanks to this method, you can quickly and accurately diagnose heart diseases and begin treatment.

Despite all the advantages, AVF retraction also has its disadvantages. For example, with some heart conditions, electrodes may give false results. Also, AVF retraction can be difficult for some patients, especially those with circulatory or heart problems.

Overall, AVF lead is an important method for diagnosing heart disease and can help doctors make a diagnosis quickly and accurately. However, before carrying out this method, it is necessary to ensure its safety for the patient.

__AVF__ lead is an enhanced O. ECG (electrocardiography), in which the active electrode is placed on the left lower limb. To ensure the accuracy and reliability of the research results, it is necessary to determine the most significant morphological characteristics of each of the ECG waves. These morphological changes reflect the electrical activity of various parts of the heart. The ECG recording values ​​are between the isoline and the demarcation line. The isoline is a straight line on a graph that shows the neutral electrical activity of the heart and is compared to the horizontal axis, and it should start from the point where the recording begins until the end of the recording. The demarcation line is a vertical straight line on the ECG graph that separates the upper and lower waves of the electrograms. They relate to the vertical axis.

One of the most important characteristics of the recorded O. ECG graph is the horizontal recording of the time axis. It shows the regularity of the heart rhythm. This interval is located below the isoline. Then, to understand the recording quality, we look at the time interval that lies directly below the demarcation line, called the ST interval. These are the characteristics
