| Term | Definition |
|---|---|
| LV volume systole IVC | no volume, all valves are closed |
| LV volume systole VE | Aortic valve open, decreased volume as blood is pushed to systemic circulation |
| LV volume diastole IVR | No volume change, ventricles are relaxed |
| LV volume diastole VF | Mitral valves open , Increased volume as blood flows from atria to ventricles |
| End diastolic volume (EDV) | Max volume in LV (diastole) 130 ml |
| End systolic volume (ESV) | Blood remaining in LV at systole (contraction) 60 ml |
| SV | Volume of blood pumped out with each beat |
| Ejection fraction (EF) | Percent of volume ejected during ventricular contraction |
| LV pressure systole IVC | increased pressure in left ventricle, PLV exceeds P aorta = aorta valve open |
| LV Pressure diastole IVR | Aorta valves close, pressure left ventricle decreased |
| Diastolic Blood Pressure (DBP) | Min. p aorta before the next ejection begins (60-80) |
| Systolic Blood pressure (SBP) | Max P aorta during ventricle ejection (100-120)= Peak SP |
| S1 Lub | AV closed |
| S2 Dub | semilunar closed |
| P wave | atrial depolarization; spreading signal across the atria |
| QRS Complex | ventricular depolarization = ventricular systole |
| T wave | Ventricular re-polarization= ventricular diastole |
