Angiographic/ LV Fx
Angiographic/ Left Ventricle Function Calculations
Question | Answer |
---|---|
Stroke Volume formula | End Diastolic Volume - End Systolic Volume |
SV= | EDV-ESV |
Ejection Fraction | SV/EDV |
What is Stroke Volume? | Amount of blood pumped by the left ventricle of the heart in one contraction |
SV divided by EDV = ? | EF |
Normal EF | 50-60% |
Angiographic CO (Cardiac Output) | SV X HR / 1,000 |
Stroke Volume MULTIPLIED BY Heart Rate DIVIDED BY 1,000 = | Angiographic CO |
Cardiac Index (Angiographic) | CO/BSA |
Cardiac Output DIVIDED BY Body Surface Area = | Angiographic Cardiac Index |
To determine the SV, EF, CO and CI, what information do you need? | EDV, ESV, HR, BSA |
CO=SV X HR | Angiographic Cardiac Output |
SV= CO / HR | Angiographic Stroke Volume |
TSV= EDV-ESV | REGURGITANT total stroke volume |
