What are symptoms of posterior MI?

What are symptoms of posterior MI?

Posterior myocardial infarction, like other types of myocardial infarction, classically presents with chest pain. Patients often describe the pain as crushing substernal chest pain or pressure.

How is posterior MI detected in ECG?

In this ECG, posterior MI is suggested by the presence of:

1. ST depression in V2-3.
2. Tall, broad R waves (> 30ms) in V2-3.
3. Dominant R wave (R/S ratio > 1) in V2.
4. Upright terminal portions of the T waves in V2-3.

What leads show right-sided MI?

A complete set of right-sided leads is obtained by placing leads V1-6 in a mirror-image position on the right side of the chest (see diagram below) It may be simpler to leave V1 and V2 in their usual positions and just transfer leads V3-6 to the right side of the chest (i.e. V3R to V6R)

How can you tell right-sided MI?

The clinical signs of this are increased right-sided heart pressures, increased pulmonary artery (PA) systolic pressures, and decreased left ventricular preload. Symptoms may include peripheral edema, especially distention of the jugular vein, hypoxemia, and hypotension.

How is posterior wall MI diagnosed?

The ECG findings of an acute posterior wall MI include the following:

1. ST segment depression (not elevation) in the septal and anterior precordial leads (V1-V4).
2. A R/S wave ratio greater than 1 in leads V1 or V2.
3. ST elevation in the posterior leads of a posterior ECG (leads V7-V9).

Why do we do right sided ECG?

All patients with inferior wall myocardial infarction should have a right-sided ECG. ST-segment elevation in lead V4 R is the single most powerful predictor of right ventricular involvement, identifying a high-risk subset of patients in the setting of inferior wall myocardial infarction.

How is right-sided MI treated?

The current treatment of RVMI patients, other than the optimization of RV and LV preload with intravenous fluids, the administration of inotropic agents, and revascularization, includes the maintenance of atrioventricular synchrony, intra-aortic balloon pump counterpulsation, and more intensive mechanical support.

How is right sided MI treated?

What is the difference between angina and MI?

The key difference between angina and a heart attack is that angina is the result of narrowed (rather than blocked) coronary arteries. This is why, unlike a heart attack, angina does not cause permanent heart damage.
