cardiovascular system basics
kisvérkör és nagyvérkör neve angolul
Pulmonary circuit
systemic circuit
What causes it?
It is caused most often by
atherosclerosis, which is the gradual buildup of fatty deposits on the inner lining of the artery walls.
Where are the carotid arteries located?
On either side of your neck.
What do you feel if you have arrhythmia?
Fluttering, pounding, racing heartbeat. Or your heart may beat too slowly or with an irregular rhythm.
parts of the heart (kamra, pitvar, sövény és 3 billentyű a quizletből. Ha valaki tudja a 4.-et az kap egy kepzeletbeli buksi simit :) )
Ventricle
atrium
atrioventricular septum
mitral valve
tricuspid valve
pulmonic valve
aortic valve
What happens in the body during coronary heart disease?
Atherosclerosis progressively narrows the artery and decreases the blood flow. This process may be compared to the gradual buildup of lime deposits in a pipe that finally plug the pipe completely.
Coronary artery disease affects the arteries that supply blood to the heart muscle.
Carotid stenosis symptoms.
Blurred vision
confusion
vertigo
tinnitus
How do you diagnose arrhythmia?
An electrocardiogram (EKG, ECG) is the most common test for diagnosing arrhythmias.

Name the 3 most common coronar artery diseases, and explain one.
Angina-
It occurs when narrowing of the coronary artery temporarily prevents an adequate supply of blood and oxygen to meet the demands of the working heart muscle. Usually no permanent damage.
heart attack-
A heart attack usually occurs when a blood clot suddenly and completely blocks a diseased coronary artery, resulting in the death of the heart muscle cells supplied by that artery.
sudden cardiac death-
Sudden death may occur as a complication of a heart attack, most commonly within 1 to 2 hours after the beginning of heart attack symptoms. More often it occurs independent of a heart attack. But in this kind of death, underlying atherosclerotic heart disease is usually present. (This one is confusing I know, you will learn about it.)
Carotid stenosis risk factors
Smoking
alcohol
high cholesterol level
high triglycerides
high blood pressure
diabetes mellitus
How do you treat arrhythmia?
For example: Cardiac resynchronization therapy uses a pacemaker to restore normal heartbeat timing.
medications
surgery
