Rv Infarction Treatment

Learn about the symptoms causes diagnosis and treatment of this life threatening condition.

Rv infarction treatment.

Right ventricular infarction complicates up to 40 of inferior stemis. Right ventricular failure may limit left heart filling via a decrease in co ventricular interdependence or both. The 2012 european society of cardiology esc guidelines for management of patients with st segment elevation myocardial infarction stemi notes that elevation of the st segment 1 mv in v1 and v4r is suggestive of right ventricular infarction. Oxygen was not given as the patient reported and presented no signs of dyspnea.

Echocardiography typically demonstrates right ventricular dilatation low pulmonary arterial pressure dilated hepatic veins and varying degrees. Cardiac mri studies indicate that a significant minority of anterior mis have rv involvement as well. Isolated rv infarction is extremely uncommon. Approximately one third to one half of patients with acute inferior lv infarction and accompanying rv infarction show the effects of lv volume underload 14 16 for many years physiologic.

St segment elevation in v4r is considered to be diagnostic for right ventricular infarction. 50 mcg of fentanyl. Acute myocardial infarction mi involving only the right ventricle is an uncommon event. An acute myocardial infarction is a heart attack.

However any st elevation in the right v leads 3 through 6 should signal suspicion for a right sided mi. A trial dose 0 4 mg ntg sl was given as rv infarction is a relative contraindication. Ringers lactate 500 ml. More often right ventricular mi rvmi is associated with acute st elevation mi of the inferior wall of the left ventricle and occurs in 30 to 50 percent of such cases rvmi is associated with higher in hospital morbidity and mortality compared with patients with a similar infarction.

Treatment of patients with right ventricular dysfunction and shock has traditionally focused on ensuring adequate right sided filling pressures to maintain co and adequate left ventricular preload.
