Which leads show inferior STEMI?

Upon ECG analysis, inferior STEMI displays ST-elevation in leads II, III, and aVF. There are subtle differences in the ECG pattern depending on the artery occluded.

What does posterior STEMI look like on 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.

What is posterior STEMI?

Posterior myocardial infarction occurs when the posterior coronary circulation becomes disrupted. The two main branches of the coronary circulation are the right coronary artery and the left main coronary artery.

What is inferior STEMI?

An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.

What is inferior posterior STEMI?

an inferior STEMI. An anterior STEMI is the front wall of the heart, and the most serious. A posterior STEMI is the back wall of the heart. An inferior STEMI is the bottom wall of the heart.

What is inferior posterior myocardial infarction?

Posterior wall myocardial infarction occurs when circulation becomes disrupted to the posterior heart. It commonly cooccurs with inferior or inferolateral MI, but when in isolation, posterior myocardial infarction represents a diagnostic challenge.

Which ECG lead looks at the inferior wall?

The arrangement of the leads produces the following anatomical relationships: leads II, III, and aVF view the inferior surface of the heart; leads V1 to V4 view the anterior surface; leads I, aVL, V5, and V6 view the lateral surface; and leads V1 and aVR look through the right atrium directly into the cavity of the …

How do I know if I have anterior or posterior STEMI?

Think of things backwards. These are the septal and anterior ECG leads. The MI is posterior (opposite to these leads anatomically), so there is ST depression instead of elevation. Turn the ECG upside down, and it would look like a STEMI.

When applying electrodes for a 12 lead ECG Where should the v1 lead be placed?

Proper 12-Lead ECG Placement

ELECTRODE	PLACEMENT
V1	4th Intercostal space to the right of the sternum
V2	4th Intercostal space to the left of the sternum
V3	Midway between V2 and V4
V4	5th Intercostal space at the midclavicular line

What is inferior posterior?

Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body).
