Week 4 Flashcards
cardiopulmonary resuscitation (CPR)
the attempt to restore cardiac and pulmonary function
diaphoresis
sweat, perspiration, or sweaty
electrocardiogram (ECG, EKG)
record of electric signals of heart
mediastinum
area between the lungs containing the heart, aorta, vena cava, esophagus, and trachea
phlebotomy
taking blood from a vein
sternum
long, flat bone forming the center of the anterior wall of the chest
aorta
main trunk of the systemic arterial system

murmur
abnormal heart sound heard with a stethoscope when a valve closes or opens abnormally
sinus rhythm
the normal (optimal) heart rhythm arising from the sinoatrial node
systole
contraction of the heart muscle
vital signs
a procedure during a physical exam in which temperature, pulse, respirations, and blood pressure are measured to assess general heath and cardiorespiratory function
cardiomyopathy
disease of the heart muscle, myocardium
cardioversion
restoration of a normal heart rhythm by electic shock
defibrillation
instrument for defibrillation
pacemaker
device that regulates cardiac electrical activity
palpitation
forcible, rapid beat of the heart felt by the patient
