Figure 3. The electrical activity on an ECG (EKG). The areas represented on the ECG are summarized below: V1, V2 = RV; V3, V4 = septum; V5, V6 = L side of the heart; Lead I = L side of the heart; Lead II = inferior territory; Lead III = inferior territory; aVF = inferior territory (remember ‘F’ for ‘feet’) aVL = L side of the heart; aVR . 1. On a right-sided ECG, V1 and V2 remain on the same place. V3 to V6 are placed on the same place but mirrored on the chest. So V4 is in the middle of the right clavicle. The ECG should be marked as a Right-sided ECG. V4R (V4 but right sided) is a sensitive lead for diagnosing right ventricular infarctions. 2.

What Is V1 And V2 In EcgA normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm). . V4 - V6 and a negative deflection with a large, deep S in aVR, V1 and V2; in general, proceeding from V1 to V6, the R waves get taller while the S waves get smaller. At V3 or V4, these waves . V1 fourth intercostal space to the right of the sternum V2 fourth intercostal space to the left of the sternum V3 placed diagonally between V2 and V4 V4 between ribs 5 and 6 in the midclavicular line V5 placed on the same level as V4 but in the anterior axillary line V6 placed on the same level as V4 and V5 but in the midaxillary

V1 is the only standard ECG lead that looks directly at the right ventricle. Lead III is more rightward facing than lead II and hence more sensitive to the injury current produced by the right ventricle. Clinical Significance of RV Infarction.

Anterior = V2-5. Anteroseptal = V1-4. Anterolateral = V3-6, I + aVL. Extensive anterior / anterolateral = V1-6, I + aVL. NB: While these definitions are intuitive, there is often a poor correlation between ECG features and precise infarct location as determined by imaging or autopsy. Ekg With St Elevation
