CH 9 MED
| Term | Definition |
|---|---|
| valvul/o | valve |
| arti/o | atrium |
| sept/o | septum |
| ventricul/o | ventricle |
| cardi/o | heart |
| coron/o | heart |
| aort/o | arota (the vessel that carries blood from the left ventricle to the systemic circulation). |
| arteri/o | artery (muscular vessel that takes blood away from the heart). |
| arther/o | fatty plaque |
| phleb/o, ven/o | vein (vessels that take blood back to the heart) |
| pectoralgia | pain in the chest (not necessarily due to the heart) |
| angina pectoris | chest pain due to irregular flow to the heart |
| palpitation | rapid or irregular beating of the heart |
| arrhythmia, dysrhythmia | irregular heartbeat |
| endocardium | inner lining of the heart |
| myocardium | middle layer of the heart, made of muscle |
| epicardium | tissue lining the outside of the heart |
| pericardium | tissue around the heart |
| vena cava | is a large-sized vein that returns blood the right atrium. It is divided into the superior vena cava and the inferior vena cava |
| superior vena cava | cava collects blood from the head, neck, upper chest, and arms |
| inferior vena cava | collects blood from everywhere else (the lower body regions). |
| diastolic pressure | – pressure on vessel walls while the heart is in diastole (relaxing) |
| systolic pressure | – pressure on vessel walls when the heart is in systole (contracting) |
| systemic circulation | circulation from the heart to everywhere except the lungs and heart |
| circulation | – moving blood through the vessels and back to the heart |
| pulmonary circulation | circulation from the heart through pulmonary vessels to pick up oxygen and then back to the heart |
| coronary circulation | circulation to the heart muscle and then back to the heart (to the right atrium) |
| congestive cardiomyopathy, dilated cardiomyopathy | heart cannot pump out all of the blood, causing the heart to become stretched and dilated and the pumping of blood to weaken/slow |
| hypertrophic cardiomyopathy | enlarged heart muscle obstructs flow |
| restrictive cardiomyopathy | stiffened heart muscle restricts filling, therefore amount of blood heart pumps is reduced |
| ABB: NSR | normal sinus rhythm |
| Abb: A-fib | – atrial fibrillation (atrial not contracting; muscle is quivering) |
| Abb: SCA | sudden cardiac arrest (heart not beating) |
| Abb: ASD | atrial septal defect |
| Abb: VSD | ventricular septal defect |
| Abb: MVP | mitral valve prolapse (valve does not close properly, allowing blood to back flow into the left atrium when the left ventricle contracts) |
| Abb: CO | – cardiac output (amount of blood pumped by the heart in one minute, measured in liters) |
| Abb: SV | – stroke volume (amount of blood ejected by the ventricle in one contraction, measured in milliliters) |
| Abb: ECHO | echocardiogram |
| Abb: TEE | transesophageal echocardiogram |
| Abb: CTA | computed tomographic angiography |
| ABB: EKG | – electrocardiogram (the K comes the German spelling for heart – kardi/o) |
| Abb: MRA | – magnetic resonance angiography |
| Abb: CHF | congestive heart failure (heart is weak and cannot pump effectively, causing blood to back up and cause congestion in veins) |
| Abb: MI | – myocardial infarction (heart muscle death, usually due to prolonged myocardia ischemia, which is usually due to CAD) |
| Abb: CAD | – coronary artery disease (presence of plaque in coronary artery that reduces blood flow to the heart muscle) |
| Abb: CABG | coronary artery bypass graft |
| Abb: BP | blood pressure (used to determine normotension, hypertension, and hypotension) |
| Abb: CTA | computed tomographic angiography (use CT scan to obtain an x-ray of the coronary arteries) |
| Abb: MRA | magnetic resonance angiography (use MRI to obtain image of coronary arteries) |
| Abb: PCI | percutaneous coronary intervention (procedures that are completed by threading tools into vessels and into the heart) |
| Abb: AA | abdominal aortic aneurysm |
| ABB: DVT | deep vein thrombosis |
| ABB: HTN | hypertension |
