''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 isthe closest to the laterale wall of the left ventricle.

In case of an inferior wall infarct, extra leads may be used:
In case of an inferior wall infarct, extra leads may be used:
#In a right side 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. On the ECG it should be marked that it is a ''Right sided ECG''. V4R (V4 but right sided) is a sensitive lead to diagnose right ventricular infarction.

#Leads V7-V8-V9 can be used to diagnose a posteriorinfarct. It is means that after V6, leads are pkaced towards the back. See the chapter[[Ischemia]] for other ways of diagnosing posterior infarction.
