Question | Answer |
---|---|
Cardiac Output | refers to the amount of blood pumped by each ventricle during a given period |
Contractility | refers to the force generated by the contracting myocardium |
Diastole | The pressure measured when the ventricles are relaxed is called diastolic blood pressure. |
JVD | Jugular Vien Distension |
Hypertention | A sustained elevation of systemic blood pressure to a level that places the patient at increased risk for target organ damage |
Atrium | Two upper hollow chambers within the heart. |
Pulmonic Valve | The pulmonic valve divides the right ventricular outflow tract from the pulmonary artery |
stroke volume | the amount of blood ejected per heartbeat |
preload | the degree of stretch of thecardiac muscle fibers at the end of diastole |
afterload | the amount of resistance to ejection of blood from the ventricle, is the second determinant of stroke volume |
ejection fraction | it is the percentage of the end-diastolic volume that is ejected with each stroke |
S1 first heart sound | closure of the mitral & tricuspid valves creates the first heart sound |
S2 second heart sound | closing of the aortic and pulmonic valves produces the second heart sound |
Hypotension | Blood pressure lower than needed for adequate tissue perfusion and oxygenation. |
LDL | is referred to as the ‘bad cholesterol.’ It is the main lipid component of the atherosclerotic plaque and is considered bad cholesterol because increased levels reflect increased tendency to CAD. |
