[Right ventricular function and the hemodynamic status of patients with unstable stenocardia]. / Funktsiia pravoho shlunochka i stan hemodynamiky u khvorykh z nestabil'noiu stenokardiieiu.

With the purpose of studying the condition of haemodynamics and function of the right ventricle in 28 patients with unstable stenocardia paired transesophageal electrocardiostimulation and bicycle ergometry [correction of veloergometry] were done with recording of echocardiographic indicators at the height of stress-tests. Important changes were identified in the right ventricular ejection fraction peculiar to changes of end-diastolic and end-systolic volumes in conditions of simulating myocardial infarction.
