Encomprises the lateral side of the left ventricle. This is supplied with blood by the RCX or the MO. The MO, the '''marginalis obtusis''' is a sidebranch between the LAD and the RCX. In case of a lateral infarct, the maximal ST elevation is in lead V7 and the maximal depression in V2. <cite>Wung</cite> | |||
