| Question | Answer |
|---|---|
| How long does it take for the brain to become irreversibly damage without good blood flow? | 4 to 5 minutes |
| How much does the heart weigh? | 8 to 10 ounces |
| How does blood flow through the heart? | See picture on study guide |
| What does a murmur mean? | it just means that your heart is making a funny noise, it could be a sign that there is something really wrong with your heart |
| What does a pacemaker do? | it is an electronic device that keeps your heart from beating too slow |
| What causes the heart sounds that you hear with your stethoscope? | The heart sounds heard through a stethoscope are caused by the closing of the heart valves. |
| Where are the Purkinje fibers located? | they are located within the ventricles |
| What is an arrhythmia? | any change from the normal rate and rhythm of the heart |
| What are statins? | drugs used to lower your cholesterol and hence your chance of a heart attack and stroke |
| Why do we care about hypotension? | not unless you are having symptoms |
| how often do you need to exercise per day to reduce your risk of heart disease? | 30 minutes per day most days of the week |
| What is an invasive procedure? | a procedure that penetrate the skin or a body cavity |
| Your total cholesterol should be below what number? | < 150 mg/dl |
| What is angina pectoris? | chest pain caused by your heart not getting enough oxygen |
| What is tachycardia? | a heart rate greater than 100 bpm |
| Describe the electrical system of the heart? | The SA node starts the heart beat, --> AV node, delay, --> bundle branches,--> Purkinje fibers --> heart muscles |
| endocardium | inner most layer of the heart creates the valves, and comes in contact with the blood, |
| myocardium | (biggest layer, middle layer, muscle layer moves the blood), |
| pericardium | ( has two layers epicardium {aka visceral pericardium}, and parietal pericardium) |
| What are the 3 layers of the heart | endocardium myocardium pericardium |
| Where is the apex of the heart? | It lies on the diaphragm and points to the left of the body. |
| cardiopulmonary resuscitation = | required for all health care workers, pushing on the chest and using an AED to zap the heart back into rhythm |
| ALS= | advanced life support = CPR + giving drugs |
| PALS= | pediatric advanced life support= ALS for kids |
| EKG interpretation: | electrocardiogram interpretation understanding what is going on with the heart based on what you are seeing on an EKG |
| Please describe the flow of blood through the cardiovascular system. | See picture in the study guide |
| Where are each of the heart valves located? | See picture in study guide |
| What is the stroke volume? | How much blood the heart pumps out per beat |
| What does the QRS mean on an EKG? | the ventricles (the bottom part of the heart is depolarizing/contracting) |
| What does a normal lipid panel look like? | total cholesterol, LDL, HDL, and Triglycerides |
| Norms for: Total Cholesterol LDL HDL VLDL Triglycerides | Total Cholesterol < 150 mg/dl LDL < 100 mg/dl HDL > 60 mg/dl VLDL < 30 mg/dl Triglycerides < 90 mgl/dl |
| 26 CAD: | narrowing of the arteries that supply the heart |
| 27 Holter monitor= | small, portable battery-operated EKG machine that measures your heart's electrical activity for 1 to 2 days |
| 28 tissue plasminogen activator= | used to dissolve blood clots |
| 29 Lipid panel= | measures LDL, VLDL, HDL, triglycerides |
| 30 diuretic= | a drug that makes you pee out extra fluid in your body |
| 31 cardiac catherization = | a catheter is inserted and fed into the chamber of the heart, where dye is inserted and pictures are taken |
| 32 murmurs= | a funny noise made by your heart and could be a sign that there is a problem with your heart valves |
| 33 third degree heart block= | called complete heart block the top and bottom parts of the heart are not talking to each other |
| 34 cardiac stents = | tiny webbed, stainless steel devices used to keep the artery open |
| 35 pacemakers= | keeps heart from beating too slowly surgically implanted battery-operated electronic device to regulate the rhythm of the heart and keep it |
| 36 where does a fetus get it's oxygen from? | from the placenta/mom |
| 37 how does oxygen flow through the body? see question | see picture on study guide |
| 38which blood vessels are the largest and which are the smallest? | veins, arteries, capillaries |
| 39 what is a congenital heart defect? | you are born with a bad heart |
| 40 What causes a stroke? | you get a blood clot or an artery in your brain burst |
| 41 what is portal circulation? | It is a branch of the general circulation, it allows the liver to remove poisons from your digested food, so veins from your digestive organs goes into the liver and the liver also gets the hepatic artery so it will have enough oxygen to do it's job. |
| 42 please understand fetal circulation: | See study guide |
| 43 what is a cerebral hemorrhage: | a blood vessel in the brain breaks |
| 44 what is peripheral vascular disease= | blocked arteries outside of the heart and the brain |
| 45 why is hypertension called the silent killer = | you may not have any symptoms until you have a heart attack, stroke, kidney failure or something very severe |
| 46 what is gangrene = | is the death of body tissue as a result of an insufficient blood supply caused by disease or injury. |
| 47 what is an embolism = | a traveling blood clot |
| 48 where is the popliteal pulse = | a pulse behind the knee |
| 49 where is the brachial pulse | = in the upper arm and elbow |
| 50 what is the foramen ovale = | an opening in the atrial septum |
| 51 what is the hepatic vein = | deoxygenated blood that leaves the liver after the liver has filtered the blood from the GI system |
| 52 how is pulse pressure calculated= | substract the system blood pressure from the diastolic blood pressure |
| 53 what is the most common symptom of a cyanotic heart defect= | cyanosis |
| 54 what is considered prehypertension | 120-129/ less than 80 |
| 55 what is considered hypotension= | a systolic blood pressure less than 90 |
| 56 arteriole= | a small branch of an artery |
| 57 phlebitis = | inflammation of the lining of the vein |
| 58 arteriosclerosis = | arterial walls thicken because of a loss of elasticity as aging occurs |
| 59 hemiplegia = | paralysis on one side of the body |
| 60 cyanosis = | blueness of the skin |
| 61 atherosclerosis = | hardening of the arteries by the deposition of fat |
| 62 hypoperfusion = | not enough blood flow to the organs of the body |
| 63 tunica adventitia | the outer layer of the arterial wall |
| 64 vascular= | blood vessels |
| 65 dysphasia = | difficulty with speech or inability to say what one wants to say |
