A study of ventricular electrogenesis and contractility in acute pressure overload of the right heart ventricle.
A model of fat embolism induced acute pressure overload of rabbit right ventricle of heart is presented. A decrease in right ventricular contractility is registered as early as the first minutes after loading. Changes in spatial magnitude and polar coordinates of vectors of ventricular depolarization, and myocardial ischemia manifestations are recorded. The changes in electrogenesis described are attributed basically to ensuing development of hemodynamic disorders.
