Acute Myocardial infarction (AMI)
A heart attack is occurring or more succinctly death of cardiac muscle is occurring
Angina
Squeezing or
... [Show More] crushing like chest pain that last a few minutes at a time; associated with the heart muscle not receiving enough blood to contract easily
Aneurysm
The bulging out of an arterial wall at a weak point. Weaknesses in the walls are often created by atherosclerosis. These weak points can burst and cause a person to bleed to death
Asymptomatic
Condition that presents no symptoms that are apparent to the patient
Atherosclerosis
A form of arteriosclerosis where the walls of arteries thicken due to an increase in smooth muscle fiber and fatty deposits known as plaque.This condition is often associated with coronary artery disease
Arrhythmias
irregular heart rhythms that are often associated with heart attacks resulting in deaths
Arteriosclerosis
A disease which results in the hardening of arteries due to thickening and loss of elasticity. Note: It is common mistake to refer to arteriosclerosis as the calcification artery walls and atherosclerosis as fatty plaque thickening of artery walls
Bradycardia
Heart rhythm is slow, less than 60 bpm
Cardiac Output
the volume of blood pumped through the heart in one minute, affected by the blood pressure and heart rate.
Coronary artery disease (CAD)
Disease of the coronary arteries that causes them to narrow and reduces blood flow to the cardiac muscle. CAD can be caused by atherosclerosis, spasms of the coronary artery or blood clots
Disystole
The relaxation phase of the heart beat, when the ventricles open up to receive blood from the atria
Embolus
Any debris floating through the blood stream; it could be a blood clot, or other debris caused by an injury that breaks lose and enters the blood stream. An embolus can block an artery, and prevent blood flow to a major organ such as the heart thus becoming an "obstruction"
Hypoperfusion syndrome (shock)
Oxygen and nutrients are not reaching the tissues of the body as a result of poor circulation or lack of blood volume
Perfusion
Sufficient blood flow to cells or tissues
systole
contraction phase of the heart beat, specifically the ventricles as they eject blood outward to the aorta and the lungs.
Tachycardia
Heart rhythm that is more than 100 bpm
Thrombus
Term used to describe a blood clot that has broken loose from the blood vessel wall
Ventricular fibrillation
Heart muscles twitch and vibrate but do not produce an actual beat or contraction therefore no circulation of blood occurs
Ventricular tachycardia
Heart rate is fast over an extended period, too fast to create enough pressure to produce a pulse, this not achieving adequate circulation. Electrical impulse originate from the ventricle.
The heart is supplied with blood by what arteries?
Coronary Arteries
What are the chambers of the heart?
2 atriums and 2 ventricles
What receives blood?
Atrium
What sends blood?
Ventricles
How does blood flow?
Right atrium->Right Ventricle ->Lungs ->Left Atrium ->Left Ventricle -> Aorta
Describe conduction of Heart
SA Node -> AV Node ->Bundle of his -> Right and left bundle branches -> Purkinje fibers
When does a heart attack happen?
When the blood supply to the heart muscle is blocked
Where does a heart attack usually happen?
Left Ventricle
What is congestive heart failure (CHF)?
When the muscles don't work, blood [Show Less]
