Cardiovascular
H.I.T
| Term | Definition |
|---|---|
| Cardiovascular System | Is the system that pumps blood through the body via the heart & blood vessels |
| Heart | Is a large muscle that acts like a pump, moving blood through the & veins. |
| Pericardium (pericardial sac) | A double - walled sac composed of membranous tissue that surrounds the heart |
| Parietal pericardium ( fibrous pericardium) | Is the outermost layer |
| Visceral pericardium (serous pericardium) | Is the inner layer of this double- walled sac |
| Pericardial fluid | Which prevents the two layers from rubbing against each other |
| Epicardium | Outermost layer of the heart |
| Myocardium | Is the middle & the thickest layer, & is the cardiac muscle |
| Endocardium | Is the innermost, sometimes called the lining of the heart |
| Atria | The upper chambers receive blood from the veins |
| Ventricles | The lower chambers send blood to the arteries |
| Sinoatrial node (SA node) | Is found where the superior vena cava & the right atrium meet |
| Atrioventricular node (AV node) | Directs the impulses to the ventricles, causing them to contract |
| Bundle of His | The conduction fibers that cause contraction |
| Pericardiocentesis | Is a procedure in which the physician removes fluid from the pericardial space |
| Tube pericardiostomy | Fluid is drained from the pericardial space |
| Cardiac pacemaker | Is used to correct & manage heart dysrhythmias |
| Pulse generator | That contains a lithium battery as its source of power |
| Electrode | Is inserted into the heart through the subclavian vein & advanced to the right ventricular apex |
| Single- chamber system | Has one electrode in either the right atrium or the right ventricle |
| Dual- chamber system | Has two electrodes one in the right atrium & one in the right ventricle |
| Pacing cardioverter- defibrillator | It emits defibrillating shocks that stimulate the heart |
| Aortic valve | Sits between the aorta & the left ventricle, is one of the main valves of the heart |
| Mitral valve | Is the valve between the left atrium & left ventricle |
| Trucuspid valve | Is the valve that lies between the right atrium & right ventricle |
| Pulmonary valve | The valve is one of the main valves of the heart & sits between the pulmonary artery & the right ventricle |
| Endarterectomy | Is a procedure used to remove the plaque deposits from blood vessels |
| Angioplasty | Is a procedure in which a balloon is inflated in the vessel to push & flatten plaque against the vessel wall |
| Coronary artery bypass (CABG) | Are types of grafts performed on the heart that are completed using a vein, an artery, or a combination of a veinv& |
| Anomaly | Is an abnormality or a deviation from the norm in a structure |
| Ventricular assist device (pVAD) | Is inserted to assist a weakened heart in ejecting blood to the body via a mechanical pump |
| Vessels | Are structures that move fluid through the body |
| Arteries | Move oxygen-rich from the heart to the rest of the body |
| Veins | Move the deoxygenated blood to the heart |
| Aneurysm | Is an area in an artery that becomes weakened |
| Thromboendarterectomy | A surgical incision that is made into an artery to remove a thrombus or plaque & the arterial lining |
| Angioscopy | Is a procedure in which a fiber-optic scope is used to visualize the interior of a noncoronary vessel |
| Nonselective placement | Means the catheter is functioning in the vessel punctured & doesn't go into any other vessel |
| Selective placement | Means that the catheter moves into one of the great vessels off the aorta, not including the vessel punctured for access |
| Venous access device | Is a device or catheter that allows access to the venous system |
| Central venous access device (CVA device) | Is a catheter classified as such if the tips ends in the subclavian, brachiocephalic, superior or inferior vena cava, or right atruim |
| Insertion | When a catheter is placed in a newly established venous access |
| Repair | Involve fixing, not replacing, either the catheter or port/pump |
| Partial replacement | Involves replacement of only a catheter component, not the whole device |
| Complete replacement | Replacement of the whole device by the same access site |
| Removal | Involves the removal of the entire device |
| Ligation | The act of tying off blood vessels & dividing & stripping vessels |
| AED | Automated external defibrillator |
| A-fib | Atrial fibrillation |
| AICD | Automated implantable cardioverter- defibrillator |
| AS | Aortic stenosis |
| ASD | Atrial septal defect |
| ASHD | Arteriosclerotic heart disease |
| BBB | Bundle-branch block |
| CABG | Coronary artery bypass graft |
| CAD | Coronary artery disease |
| CC | Cardiac catheterization |
| CCU | Coronary care unit |
| CHD | Coronary heart disease |
| CHF | Congestive heart failure |
| DVT | Deep vein thrombosis |
| EKG | Electocardiogram |
| HTN | Hypertension |
| MI | Myocardial in farction |
| MVP | Mitral valve prolapse |
| PAD | Peripheral artery disease |
| pVAD | Percutaneous ventricular assist device |
| PVD | Peripheral vascular disease |
| Arteries | Carry oxygen-rich blood from the heart to the body |
| Veins | Carry deoxygenated blood from the body back to the heart |
| Heart | A muscular organ, located between the lungs to the left of the midline of the body, that pumps blood throughout the body |
| Hypertension | Is an increase in blood pressure |
| Systolic blood pressure | The pressure on the arterial walls during the heart muscle contraction |
| Diastolic blood pressure | The pressure on the arterial walls during relaxation of the heart muscle |
| Transient hypertension | Elevated blood pressure |
| Secondary hypertension | High arterial blood pressure due to another disease |
| Ischemic heart disease | When there is an inadequate supply of blood to the heart |
| Occlusion | Constriction of an arterial blood vessel |
| Angina pectoris | Severe chest pain caused by an insufficient amount blood reaching the heart |
| Unstable angina | Is an accelerating pattern of chest pain that occurs at rest or during mild exertion |
| Acute myocardial infarction (MI) | Commonly called a heart attack, occurs when there is inadequate blood supply to a section or sections of the heart |
| Old myocardial infarction (healed myocardial infarction) | When the patient is not presenting with any symptoms |
| Acute pericarditis | Inflammation of the outer layers of the heart |
| Endocarditis | Inflammation of the inner layer of the heart |
| Myocarditis | Inflammation of the heart muscle |
