What is a posterior ECG?
What is a posterior ECG?
The ECG findings of an acute posterior wall MI include the following: ST segment depression (not elevation) in the septal and anterior precordial leads (V1-V4). This occurs because these ECG leads will see the MI backwards; the leads are placed anteriorly, but the myocardial injury is posterior.
Which leads do you move for a posterior ECG?
Posterior ECG leads (V7-V9) are applied by moving V4-V6 to under the left scapula.
Where do you place a 12 lead?

|---|---|---|
| V1 | C1 | Fourth intercostal space at the right sternal border |
| V2 | C2 | Fourth intercostal space at the left sternal border |
| V3 | C3 | Halfway between leads V2 and V4 |
| V4 | C4 | Fifth intercostal space in the midclavicular line |
How can you tell if you have a posterior stemi?
Main ECG pointers for Posterior STEMI:
- Look for deep (>2mm) and horizontal ST-segment depression in the anterior leads and large anterior R-waves (bigger than the S-wave in V2).
- Posterior STEMI often occurs along with an inferior or lateral STEMI, but can also occur in isolation.

Why is it called 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.
When should a right sided ECG be done?
All patients with chest pain should receive a 12-lead ECG early in the patient encounter. When the patient is suffering acute inferior STEMI a right-sided 12-lead ECG can help to identify right ventricular infarction.
Why is it called a 12 lead?
How do you do a right-sided 12 lead?
A right-sided 12-lead ECG is obtained. To accomplish this, the EMS crew places the precordial leads in the mirror-image position on the right side of the patient’s chest. Editor’s note: Sometimes leads V1 and V2 are left in place and only leads V3-V6 are moved over to mirror image position on the patient’s right side.
How are the names of record labels organized?
Lists of record labels cover record labels, brands or trademarks associated with marketing of music recordings and music videos. The lists are organized alphabetically, by genre, by company and by location. This article includes a music-related list of lists.

How do bands get noticed by record labels?
