lowering stress, stopping smoking, and eating less cholesterol and fatty foods; Bypass surgery or angioplasty

heart attack

what causes cardiac arrest

cardiac muscle cells lose ozygen and die

How well did you know this?

Perfectly

fibliration

when the heart beat is irregular (arrhythmia)

ventricular fibliration

normal heart rhythem disrupted because heart muscles stimulate each other too fast, making the pumping uncoordinated

Most effective way to treat cardiac arrest

defiblirator

EKG

Electrocardiogram

what does an EKG do

measures electrical events in the heart (useful in detecting arrhythmias)

Auscilation

listening to the heart

what tool is used in Ausculation

stehtescope

how many heart sounds are there

how many heart sounds are detectable

1st and second

1st heart sound

start of ventricular systole caused by the closing of the AV valves

venticular systole

venticular contraction

AV valves

Tricuspid and Bicuspid valves

2nd heart sound

start of ventricular diastole as semilunar valves close

Ventricular Diastole

ventricular relaxation

semilunar valves

aortic and pulmonary

3rd heart sound

blood flowing into ventricles

4th heart sound

contraction of the atriums

Mitral valve prolapse

dcommon valve abnormality caused by mitral (bicuspid) bave not closing properly

what happens to the heart sounds during Mitral Valve Prolapse

regurgitation of the blood causes a gurgling sound (heart murmur)

How common is Mitral Valve prolapse

10% of people 14-30 have it

how dangerous in Mitral Valve Prolapse

most people are asymptomatic and live normal, healthy lives

Treatment for severe Mitral Valve Prolapse

valve replacement surgery

CARDIAC CONDUCTION SYSTEM

Heart's specialized conduction sustem

In what order does the impuls of the Cardiac conduction system travel

SA node to AV node, to atrioventricular bundle, to the purkinje fibers, and finally to the papillary muscles

Tachycardia

faster than normal heart rate (caused by abnormal pacemaker function)

bradycardia

slower than average heart rate (caused by abnormal pacemaker function)

normal heart rate

60-100 bpm

Pace Maker

SA node

Treatment for disfunctioning pacemaker

surgically attach an artificial one

function of the atriums

recieving chambes

three arteries that branch off from the aortic arch

The brachiocephalic artery, the left carotid artery, and the left subclavian artery.

what is the chordae tendinaese

attaches to the papillary muscles, it connects the left and right atrioventicular valves together

Cardiac catherization

dye is injected into the blood to make it show up on an xray

what is an E/A ratio

ratio of blood pumped early to blood that flows through atrium

have you studied th ekg picture thing

maybe

Which wave segment of an EKG show the depolarization (contraction) of the atria?

The PR segment

Which wave segment of an EKG show the depolarization (contraction) of the ventricles?

QRS

Which wave segment of an EKG show the repolarization (relaxation) of the ventricles?

The T wave

What would the heart of a person with a murmur sound like?

Lubb-dubb-swish

\What are the basic components of blood?

Erythrocytes, Leukocytes, platelets, and plasma

How much of blood is plasma?

55%

How much of blood is plasma?

55%

How much of plasma is water?

90%

Erythrocytes?

Red blood cells that carry oxygen and Carbon dioxide

Erythrocytes?

Red blood cells that carry oxygen and Carbon dioxide

Leukocytes?

White blood cells that defend the body from toxins and foreign microbes

platelets?

Cell fragments that help with blood clotting

How are antigens responsible for blood type?

Antigens are glycoprotein molecules on red blood cells that allow the body to know that the specific red blood cell belongs in the body.

Tunicia intima

inner layer of blood vessel

Tunicia Mediaa

middle layer of blood vessel

Tunitia Adventita

outer layer of blood vessels

Tunitia externa

outer layer of blood vessels

What medical condition would you use a defiblirator

cardiac arrest

maximum pressure in the artery occuring during ventricular contraction

systolic pressure

what are the audible heart sounds produced by

closing of the valves

another name for the visceral pericardium

epicardium

visceral pericardum

outer layer of the heart

Pullmonary circulaton

the pumping of blood to the lungs and back

systemic circulation

pumping of blood throught the body

systemic circulation

pumping of blood throught the body

which chamber recieves blood from the lungs

left atrium

what causes a heart attack

When heart muscle cells start to die due to a blocked artery

blood vessel layer that contains smooth muscles

middle

where is blood pressure highest

in an artery

type of heart failure when the heart ventricles aren't adequatley pumping blood

systolic heart pressure

healthy EA ratio

80/20
