Recognition of acute right ventricular infarction by right Precordial Leads
Keywords:Recognition of acute right ventricular infarction by right Precordial Leads
Material and Methods:
Fifty consecutive patients with acute myocardial infarction who got admission at National Institute of Cardiovascular Diseases, from April 1 to July 31, 1986 form the basis of this study.All patients underwent careful clinical eva1uations. Clinically right ventricular infarction was diagnosed if following features were present simultaneously, persisting hypotension systolic blood pressure < 90mm Hg, raised Jugular venous pressure clear lung field (clinically and radiologically) cold extremities, and oliguria <300 ml urine per twenty four hours.
Out of total 50 patients 4Ei were men, 4 were women and their ages ranged from 4U to 65 years (mean b2.5). ‘l’able I gives breakup of patients based upon electrocardiographic site of myocardial infarction.
Several authors (9) have recognised of right ventricular dysfunction in the context of acute myocardial infarction but existence 01 right ventricular infarction as a clinical entity has been boosted recently by the refinements in non invasive diagnostic techniques (electrocardiography, Nuclear Ventriculography, pyrophosphates scintigraphy and echocardiography) (10).V3RV4R should be recorded as early as possible in the presence of acute inferior and posterior wall infarction, rather it should be an intrinsic part of the early electrocardiographic recording of every patient, evaluation who is. entering into hospital.
