| WHAT ARE THE 6 COMPONENTS OF THE CARDIAC CYCLE? |
|
Definition
| PRELOAD, AFTERLOAD, CONTRACTILITY, COMPLIANCE, SV, CO |
|
|
Term
|
Definition
| AFTERLOAD IS THE AoEDP. IT IS THE AMOUNT OF PRESSURE THAT THE LEFT VENTRICLE MUST GENERATE TO OPEN UP THE AORTIC VALVE. |
|
|
Term
| WHAT IS THE AoEDP DETERMINED BY? |
|
Definition
| THE DIASTOLIC RUNOFF WHICH IS -CHANGE IN AoP/CHANGE IN TIME. |
|
|
Term
| DESCRIBE WHAT THE WIGGER'S DIAGRAM SHOWS? |
|
Definition
| RELATIONSHIP BETWEEN LEFT ATRIAL PRESSURE, LEFT VENTRICLE PRESSURE, AND AORTIC PRESSURE. HE RELATED THOSE 3 TO LEFT VENTRICULAR VOLUME |
|
|
Term
| WHAT IS THE WORST CONSEQUENCE OF HTN? |
|
Definition
| THE INCREASE IN AFTERLOAD BECAUSE THE INCREASE IN AFTERLOAD MAKES THE HEART WORK HARDER |
|
|
Term
| BETWEEN THE SYSTOLIC AND DIASTOLIC WHICH ONE HAS HIGH IMPORTANCE R/T AFTERLOAD? |
|
Definition
| THE DIASTOLE BECAUSE THE HIGHER THE END DIASTOLIC PRESSURE THE HARDER THE HEART MUST WORK. |
|
|
Term
| THE SYSTOLE PRESSURE IS HOW HARD THE LEFT VENTRICLE ___ WORK HOWEVER THE DIASTOLIC IS HOW HARD THE HEART ___ WORK. |
|
Definition
| CAN, MUST. THE HIGHER THE AORTIC PRESSURE, THE HARDER THE HEART HAS TO WORK WHICH INCREASES O2 DEMAND. |
|
|
Term
| THE AORTIC VALVE CLOSES AS SOON AS WHEN? |
|
Definition
| THE VENTRICULAR PRESSURE FALLS BELOW AORTIC PRESSURE |
|
|
Term
| HOW MANY ML WILL THE ATRIAL KICK ADD OR PUSH IN TO THE DIASTOLIC VOLUME? |
|
Definition
|
|
Term
| DESCRIBE THE DICROTIC NOTCH. |
|
Definition
| CLOSURE OF THE AORTIC VALVE PLUS RECOIL OF THE ELASTICITY OF THE AORTA. THE UPWARD TICK OF THE DIACROTIC NOTCH IS CAUSED FROM THIS SNAP BACK OF THE AORTA. THE DOWNSTROKE AFTER THE DIACROTIC NOTCH IS WHEN THE BLOOD STARTS LEAVING THE AORTA. |
|
|
Term
| THE MORE RIGID THE AORTA THE HIGHER THE __ ____ IS GOING TO BE. |
|
Definition
| DIACROTIC NOTCH. THERE IS TIGHT ELASTIC RECOIL. |
|
|
Term
| WHEN DOES A PATIENT NOT HAVE A DIACROTIC NOTCH? |
|
Definition
| DURING AORTIC REGURGITATION. THERE IS A BACKFLOW OF BLOOD INTO THE LEFT VENTRICLE. |
|
|
Term
| S1 AND S2 ARE CLOSURE OF WHICH VALVES? |
|
Definition
| S1 IS AV VALVES AND S2 IS CLOSURE OF SEMI LUNAR VALVES |
|
|
Term
| WHEN IS S3 HEARD? WHAT IS THE CAUSE? |
|
Definition
| DURING DIASTOLE AND IS CAUSE OF A STENOTIC MITRAL VALVE. If we are trying to move blood through a valve that is only half open, that is going to cause turbulent flow. |
|
|
Term
|
Definition
| RIGHT BEFORE THE ATRIAL KICK |
|
|
Term
| WHEN DOES SPLITTING OF S2 OCCUR? |
|
Definition
| WHEN THE SEMILUNAR VALVES CLOSE AT DIFFERENT TIMES. |
|
|
Term
| WHAT IS A PATHOLOGICAL AND PHYSIOLOGICAL CAUSE OF SPLITTING OF S2? |
|
Definition
| PATHOLOGICAL IS BBB AND PHYSIOLOGICAL IS TAKING A DEEP BREATH. |
|
|
Term
| DESCRIBE THE PHYSIOLOGICAL CAUSE OF S2 SPLITTING. |
|
Definition
| As we take a deep breath, intrathoracic pressure decreases which causes the vena cava to expand allowing more blood to return to the R atrium. However the blood that is returning to the L side of the heart is coming from the pulmonary vasculature so we end up with a larger volume in the R side compared to the left. This means that if we begin contracting at the same time, the L ventricle empties before the R ventricle. Therefore the aortic valve will close before the pulmonic valve. |
|
|
Term
| WHEN DOES THE C WAVE OCCUR? |
|
Definition
| DURING THE ISOVOLUMETRIC CONTRACTION PHASE. |
|
|
Term
|
Definition
| LVEDV. THE PRELOAD IS THE AMOUNT OF BLOOD IN THE VENTRICLES PRIOR TO VENTRICULAR CONTRACTION. |
|
|
Term
| WHAT IS THE EQUATION FOR STROKE VOLUME? WHAT IS THE DEFINITION? |
|
Definition
| LVEDV-LVESV. VOLUME IN THE VENTRICLES PRIOR TO CONTRACTION AND VOLUME IN THE VENTRICLES AFTER CONTRACTION. SO THIS IS THE VOLUME OF BLOOD EJECTED BY A VENTRICLE AT THE END OF ONE CONTRACTION. |
|
|
Term
| WHAT IS THE EQUATION FOR CARDIAC OUTPUT? |
|
Definition
|
|
Term
| HOW IS CONTRACTIITY MEASURED? |
|
Definition
| CHANGE IS LEFT VENTRICULAR PRESSURE OVER CHANGE IN TIME |
|
|
Term
| IF THE CONTRACTILITY WERE TO DECREASE, HOW WOULD THE EJECTION PHASE CHANGE? |
|
Definition
| WE WOULD LOSE VOLUME MUCH MORE SLOWLY. |
|
|
Term
| WHAT IS THE FORMULA FOR COMPLIANCE? |
|
Definition
| CHANGE IN VOLUME/ CHANGE IN PRESSURE |
|
|
Term
| WHAT IS RESPONSIBLE FOR MORE ATRIAL FILLING FOR A LESS COMPLIANT VALVE? |
