Heart Flashcards
Arrhythmia
Change or deviation from normal heart rate
Tachycardia
Fast heart rate, 100<
Bradycardia
Slow heart beat 60>
Murmurs
When the valves of the heart fail to close properly and gurgling and hissing can be heard
Coronary artery disease
Narrowing of the coronary arteries
Myocardial infarction
Heart attack due to not enough blood supply
Angina pectoris
Severe chest pain
Where is the mitral valve located
Between the left atrium and the left ventricle
Pericarditis
Inflammation of the outer membrane covering the heart
Myocarditis
Inflammation of the heart muscle
Endocarditis
Inflammation of the membrane that lines the heart and covers the valves
Heart failure
When the ventricles of the heart fail to contract effectively
Third degree heart block
Complete heart block and no impulse is carried
Cardiac output formula
Stroke volume x heart rate
SA node or pacemaker
Send out electrical impulses that regulate or starts the heart
Purkinje fibers
Located throughout the ventricles
Electrocardiogram
Records the electrical activity of the heart
Angiography
X-ray injected in the coronary arteries to study the circulation of blood throughout the arteries
Echocardiography
Ultrasonic process used to evaluate the structures and motion of the heart
Cardiac catherizatiom
Insertion of catheter and fed into chamber of the heart
Common symptoms of the heart
Arrhythmia
Bradycardia
Tachycardia
Murmurs
Mitral valve prolapse
Valve between the left atrium and the left ventricle closes imperfectly
How does heart block occur
Interruption of the AV node message from the SA node
