Why the study?
How do chronic pressure and volume overloading alter right ventricular systolic time intervals compared to normal right ventricles?
How do chronic pressure and volume overloading alter right ventricular systolic time intervals compared to normal right ventricles?
Chronic pressure and volume overloading produce distinct alterations in right ventricular systolic time intervals, with pressure overload prolonging isovolumic contraction and volume overload prolonging ejection time.
No takes yet. Share an insight, caveat, or question.
RV systolic time intervals distinguish pressure from volume overload; hypothesis-generating for noninvasive assessment and outcomes in PH/ASD.
Curtiss et al. (1976) studied this question.
