conditions that disrupt function

abormal heart beats are called

cardia arrhythmias

cardiac arrhythmias are a result of…

damage to conduction system

cardiac arrhythmias

• abnormally slow heart rate

bradyarrhythmia

cardiac arrhythmias

• what are the three brady arrhythmias and what causes them

atrioventricular block = congenital or from surgical trauma

sinus bradycardia = caused by ANS hypotension oxygen decrease

nodal arrythmia = absence of p waves, no treatment necessary

brady arrhythmias

cardiac arrhythmias

• abnormally fast heart rate

tachyarrhythmia

what are the two types of tachyarrhythmias and what causes them?

sinus tachycardia = caused by fever and infection

super ventricular tachycardia = result in congestive heart failure

tachy arrhythmias

• caused by fever and infection

sinus tachycardia

tachy arrhythmias

• result in congestive heart failure

superventricular tachycardia

when oxygenated and deoxygenated blood mix because septum has abnormalities

septal defects

muscular wall that separates left and right side

septum

which septum is this describing

• thin and muscular

interatrial septum

which septum is this describing

• has fossa voalis

interatrial septum

which septum is this describing

• has limbus of fossa ovalis

interatrial septum

which septum is this describing

• separates right and left atria

interatrial septum

which septum is this describing

• thick and muscular

inter ventricular septum

which septum is this describing

• has membranous portion

inter ventricular septum

which septum is this describing

• has muscular portion

inter ventricular septum

which septal defect is this describing

• blood flow between two ventricles

ventricular septal defects

which septal defect is this describing

• bloow flow between 2 atria

atrioseptal defects

blood flow to heart muscle is blocked damaging heart

heart attacks

blood flow to part of brain is blocked or blood vessel in the brain bursts

stroke

weakened blood vessels bulge or rupture

aneurysm

fatty plaque builds up inside arteries narrowing them

athersclerosis

high blood pressure is called….

hypertension
