ST elevation in posterior leads V7-9

ST elevation in V7-9 suggests posterior infarction. It is detected by recording the special posterior leads by moving the V4-6 electrodes to the posterior axillary line (V7), tip of the scapula (V8) and paraspinal region (V9) keeping them in the same horizontal plane as the normal V6.
