Lead V2

Lead V2 is one of the standard electrocardiogram leads. In this lead, the active electrode is located in the fourth intercostal space along the left edge of the sternum.

This lead allows you to record the electrical activity of the heart in the area of ​​the anterior wall of the left ventricle. It is used to diagnose myocardial ischemia of the anterior wall of the left ventricle, left ventricular hypertrophy, conduction disorders and other pathologies.

Analysis of the Q wave and ST segment in lead V2 has important diagnostic value. Changes in these ECG components may indicate myocardial ischemia or infarction of the anterior wall of the left ventricle.

Thus, lead V2 provides valuable information about cardiac health and is widely used in clinical practice. Correct interpretation of the data from this lead is important for making a diagnosis and choosing treatment tactics.



Lead V is an ECG recording method that helps in diagnosing heart disease. Lead V- is a cardiac wave lead that is expressed in the plane of the anterior and lateral chest wall. The hallmark of this lead is its increased amplitude, as it contains information about ventricular activation.

Lead V includes the left lateral and superior chambers (left and right ventricles). It also reflects the functioning of the inferior wall of the atria. It is also possible to measure the vector value of the wave at a 45 degree angle to this wall. This helps visualize the shift in the electrical activity of the heart chambers in one of the two V vectors.

Full lead V includes data from multiple electrodes located along different areas of the chest. The chambers of the heart are responsible for the rapid conduction of the signal and record the electrical activity of the heart. To maximize the reliability of the heart rhythm study, the patient should be informed that he should lie quietly for as long as possible during recording.

Determining lead V is important for diagnosing arrhythmias, identifying abnormal heart rhythms and problems with conduction between the chambers. Abduction is especially useful in assessing results in cases where deep examination is used in order to facilitate access to the heart muscle, as well as in determining the state of the cardiac conduction system after treatment.
