The value of doppler echocardiography in diagnositics of right ventricular infarction
Ischemic damage of the right ventricle (RV) can lead to severe hemodynamic impairment, dramatically increases the risk of arrhythmias and makes the outcome worse in patients with inferior myocardial infarction. However, early recognition of infarction of the right ventricle with systolic disfUncton still presents a problem. Aims: evaluation of importance of electrocardiographic signs of ischemic damage of RV and Doppler echocardiographic findings of systolic disfunction of RV in infarction recognition of RV. Methods: in 100 patients with the acute inferior infarction Doppler echocardiographic studies with assessment of amplitude, velocity and velocity time integral of motion of the RV base, electrocardiography with registration of right precordial averting, physical examination and laboratory investigation were performed. Results: Electrocardiography signs of infarction of RV don't reflect the severity of systolic disfunction of RV. On the other hand, the decrease of the RV base <14 mm motion amplitude, the decrease of velocity and velocity time integral of motion of the right ventricular base <20 cm/s and < 33.3 mm can testify of significant systolic disfunction of RV. Key words: infarction, right ventricular, right ventricular base, Doppler echocardiography.
