Eufillina sample

Eufillina test - a test that allows you to set the reversibility of high blood pressure in the pulmonary circulation. Eufillina the sample is based on the peculiarities of aminophylline to reduce the pressure in the system arteries small circle and thus reduce the overload of the right part of heart.
The methodology of eufillinom samples. The patient, who is in a relaxed reclining position, record ECG in leads I, II, III (standard) and V1,3 and 5 (breast). Then injected 15-20 ml of 2.4% solution of aminophylline and after 5, 15, 30 and 60 minutes (negative test results to 2 hours.) again record the ECG in those leads. The sample is considered positive if after the introduction of aminophylline is observed decrease of the heart rate and reducing the amplitude of the wave P (0.5-1.5 mm and negative of the T wave in leads II, III, aVF and V1 1-2 mm
Interpretation of the positive eufillinom samples depends on the form of the disease the patient, because the hypotensive effect of aminophylline in the small circle of blood can be carried out at the expense of cardiotonic (when failure left heart), and by bronhorasshiryayuschimi (if hypertension is associated with bronchospasm) its properties. Possible and vasoactive (direct effect on the blood vessels) effect of aminophylline.

Eufillina sample - proposed in 1958, B. B. Kogan and P. M. Zlochevsky. Based on the ability of aminophylline to reduce the pressure in the pulmonary artery and thus reduce the overload of the right part of heart.
The sample performed as follows: ECG is performed in leads I, II, III, aVF, V1,3.5 to intravenous injection of 2.4% solution of aminophylline (aminophylline, centovallina) in the amount of 15-20 ml in 5, 15, 30, 60 minutes, and so on (in some cases up to 2 hours) after him.
The positive result of the sample is measured by ischemia rhythm and transient decrease of an amplitude of atrial teeth 0.5-1.5 mm and negative teeth Vol 1-2 mm in leads II, III, aVF, V1. There may also be a decrease in the amplitude of the wave's in leads I, V5, the increase in the total voltage.
The sample has prognostic value, indicating a certain degree of reversibility of hypertension in the pulmonary circulation, which is observed in the I and II stages of decompensation of chronic pulmonary heart, acute pulmonary heart (pulmonary embolism, bronchial-asthma status).
Application samples before surgery mitral commissurotomy can Orient available and reversibility pulmonary hypertension (trial bloodless comissurotomy). With the same purpose, is shown holding samples before pulmonaria.
