cardiovascular emergencies

TermDefinition
acute coronary syndrome group of symptoms caused by myocardium ischemia -angina -AMI
acute myocardium infarction (AMI) Heart attack - Death of a heart muscle following obstruction of blood flow to it
angina pectoris Chest pain Caused by partial or temporary blockage of blood flow to the heart muscle
anterior Front surface of the body
aorta Main artery which received blood from left ventricle and delivers to other arteries
aortic aneurysm A weakness in the wall of the aorta that makes it susceptible to rupture
aortic valve The one way valve that lies between the left ventricle and the aorta and keeps blood from flowing back into the left ventricle after the left ventricle ejects its blood into the aorta
artifact Are you tracing on an ecg that is a result of interference
asystole The complete absence of all heart electric activity
atherosclerosis A disorder in which cholesterol and calcium build up inside the walls of the blood vessels Leading to partial or complete blockage of blood flow
atrium One of two upper chambers of the heart
automaticity The ability of cardiac muscle cells to contract without stimulation from the nervous system
autonomic nervous system Part of the nervous system that controls the involuntary activities of the blood such as heart rate blood pressure and digestion of food
bradycardia Slow heart rate less than 60 beats per minute
cardiac arrest When the heart fails to generate effective and detectable blood flow
cardiac output Measure of the volume of blood circulated by the heart in one minute. - Multiply stroke volume by heart rate
cardiogenic shock State in which not enough oxygen is delivered to the tissue of the body caused by low output of blood from heart
congestive heart failure (CHF) Disorder in which the heart loses part of his ability to effectively pump blood
coronary arteries Blood vessels that carry blood and nutrients to the heart muscle
defibrillate Too shocked a fibrillating heart with specialized electric current in attempt to restore a normal rhythm
dilation Widening of a tubular structure such as coronary artery
dissecting aneurysm Condition in which the inner layers of an artery become separated allowing blood to flow between the layers
dysrhythmia Irregular or abnormal heart rhythms
hypertensive emergencies No an emergency situation created by excessively high blood pressure can cause stroke or aneurysm
infarction Death of a body tissue
inferior Heart of the body for any body part nearer to the feet
ischemia Lack of oxygen that deprives tissue of necessary nutrients resulting from partial or complete blockage of blood flow
lumen Inside diameter of an artery were other hollow structure
myocardium heart muscle
occlusion Blockage of tubular structures such as blood vessels
parasympathetic nervous system Part of the autonomic nervous system that controls vegetative functions such as digestive of food and relaxation
perfusion Adequate blood flow, oxygen and glucose to cells to meet cells needs
return of spontaneous circulation (ROSC) return of a pulse and effective blood flow to the body in PT who was previously in cardiac arrest
stroke volume Volume of blood ejected with each ventricle contraction
sympathetic nervous system Part of the body or any body part nearer to the head
syncope What are the autonomic nervous system that controls fight or flight
tachycardia Irregularly fast heart rate
thromboembolism A blood cot that has formed within a blood vessel and is floating within the bloodstream
ventricle One of two lower chambers of the heart
ventricular fibrillation Disorganized, ineffective quivering of the ventricles resulting in no blood flow in a state of cardiac arrest
ventricular tachycardia A rapid heart rhythm in which the electrical impulse begins in the ventricle instead of the atrium which may result in inadequate blood flow

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
