What is v1 and v2 in ECG?
The precordial, or chest leads, (V1,V2,V3,V4,V5 and V6) ‘observe’ the depolarization wave in the frontal plane.
Example: V1 is close to the right ventricle and the right atrium.
Signals in these areas of the heart have the largest signal in this lead.
V6 is the closest to the lateral wall of the left ventricle..
Where is the chest lead v2 placed anatomically?
Move down over the next 2 ribs and you have found the 4th intercostal space. Where this space meets the sternum is the position for V2. From this position, slide your fingers downward over the next rib and you are in the 5th intercostal space .
Why is v1 and v2 negative in ECG?
ECG – A Pictorial Primer. In right chest leads V1 and V2, the QRS complexes are predominantly negative with small R waves and relatively deep S waves because the more muscular left ventricle produces depolarization current flowing away from these leads. … In V1 the QRS are positive with tall R waves.
What direction of current do leads v1 and v2 measure?
What direction of current do leads V1 and V2 measure? V1 and V2 measure anterior forces as a positive wave and posterior forces as a negative wave.
What is normal P in ECG?
Normal ECG values for waves and intervals are as follows: RR interval: 0.6-1.2 seconds. P wave: 80 milliseconds. PR interval: 120-200 milliseconds.
What is the normal ECG result?
Normal intervals Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).
When applying chest leads you will place the v2 lead?

Where do you put a v1?
The proper location of V1 and V2 have not changed in many decades. They are located in the 4th intercostal space, just right and left, respectively, of the sternum. It is fairly easy to determine this spot using the angle of Louis as a landmark.
What view of the heart do leads v1 and v2 represent?
The six chest leads (V1 to V6) “view” the heart in the horizontal plane. The information from the limb electrodes is combined to produce the six limb leads (I, II, III, aVR, aVL, and aVF), which view the heart in the vertical plane. The information from these 12 leads is combined to form a standard electrocardiogram.
Why do they call it a 12 lead ECG?
The 12-lead ECG displays, as the name implies, 12 leads which are derived by means of 10 electrodes. Three of these leads are easy to understand, since they are simply the result of comparing electrical potentials recorded by two electrodes; one electrode is exploring, while the other is a reference electrode.
What must be done before you run the actual ECG tracing?
What must be done before you run the actual ECG tracing? You should identify and communicate with the patient, prepare the patient and the room, provide for patient privacy and safety, locate and check the equipment, load ECG paper if needed, and attach the electrodes and leads.
Where do 3 lead ECG electrodes go?
Position the 3 leads on your patient’s chest as follows, taking care to avoid areas where muscle movement could interfere with transmission:WHITE.RA (right arm), just below the right clavicle.BLACK.LA (left arm), just below the left clavicle.RED.LL (left leg), on the lower chest, just above and left of the umbilicus.
