Echocardiography Diastolic and Systolic Function| 135 QUESTIONS| WITH COMPLETE SOLUTIONS

what is systolic function? how well the heart squeezes what can ventricular systolic function help predict? disease severity clinical endpoints treatment planning what are the measures of systolic function? stroke volume and ejection fraction what is stroke volume? volume of blood ejected during systole (each beat) measured in ml what is a synonym for stroke volume? pump performance what is ejection fraction? decrease in volume relative end-diastolic volume measured in % what is a synonym for ejection fraction? ventricular function what are normal EF's? 65% for the average person 40% for extreme athletes what are the factors that affect EF and SV? contractility preload afterload ventricular geometry what is contractility? ability of myocardium to squeeze what is preload? initial ventricular pressure from end-diastolic volume what is afterload? the pressure that the ventricle must pump against left side is aortic (systematic) and right side is pulmonic (pulmonary) what is ventricular geometry? the size and shape of the ventricle what does low dependence mean? measurement is dependent on the preload and afterload (which are not easily determined by echo) what are systolic measurements we can take? EF and SV/CO
