a machine that produces and sends an electrical shock to the heart that is intended to correct the abnormal electrical pattern of the heart defibrillator
used to analyze the heart rhythm and produce a shock if necessary AED
a tracing of the signal produced by the heart’s electrical activity and used for diagnostic evaluation of the heart electrocardiogram
a disease related to the heart cardiovascular disease
Disease of the heart and Blood Vessals Cardiovascular Disease (CVD)

type of isolation precaution implemented for hospitalized patients Droplet, Airborne, Contact
adult pulse is most commonly measured at radial artery at the wrist.
patient who is having difficulty breathing dyspnea
hypertension has no known cause Essential (Idiopathic)
Circulation of the blood depends on the heart and its ability to contract or beat.
function of the heart to pump blood to and from all the tissues of the body.
heart chamber that pumps blood to the body, known as the workhorse of the heart Left ventricle
valve located between the right atrium and right ventricle Tricuspid valve
heart chamber that receives blood from the lungs Left atrium
artery that transports blood to the entire body Aorta
blood vessel that provides a pathway for deoxygenated blood to return to the lungs Pulmonary artery
chamber of the heart that receives blood from the body Right atrium
chamber of the heart that pumps blood to the lungs Right ventricle
type of valve located in the aorta and the pulmonary artery Semilunar valve
blood vessel that transports blood from the lungs to the left atrium Pulmonary vein
atrioventricular valve between the left atrium and left ventricle Mitral valve
The entire heart is enclosed in a sac of tissue pericardium
visceral pericardium, which is the outermost layer of the heart Epicardium
blood that has little or no oxygen deoxygenated blood
the contraction and relaxation of the heart cardiac cycle
contraction phase of the cardiac cycle, when the heart is pumping blood out to the body systole
circulation of blood through the heart and heart muscle coronary circulation
circulation between the heart and the entire body, excluding the lungs systemic circulation
blood having oxygen oxygenated blood
phase of the cardiac cycle when the heart is expanding and refilling; also known as the relaxation phase diastole
(Pathways) transportation of blood to and from the lungs pulmonary circulation
High Pressure, Oxygenated Blood Left Heart
Low Pressure, Deoxygenated Blood Right Heat
Which main coronary artery has more branches Left>Right
The contraction and relaxation of the heart together make up the cardiac cycle
sound of the heartbeat is made during the systolic phase The lubb sound
sound made during the diastolic phase. The dupp sound
atrioventricular valves, are open during Ventricular Diastole
The semilunar valves are open during Ventricular Systole
Oxygenated blood from the heart drains into the Left Atrium
the largest vessel in the body Aorta
ability of the heart cells to receive and transmit an electrical impulse Conductivity
heart muscle cells return to their resting electrical state and the heart muscle relaxes Repolarization
distribute electrical impulses from cell to cell throughout the ventricles Purkinje fibers
delays the electrical conduction through the heart AV node
an electrical current that initiates the contraction of the heart muscle Depolarization
ability of the heart muscle cells to shorten in response to an electrical stimulus Contractility
initiates the heartbeat SA node
branches off the bundle of His that conduct impulses to the left and right ventricles Bundle branches
ability of the heart to initiate an electrical impulse Automaticity
ability of the heart muscle cells to respond to an impulse or stimulus Excitability
Like the unique qualities of the heart, the autonomic nervous system (ANS) is Involuntary
The ability of the heart to initiate an electrical impulse without being stimulated by an outside source is Automaticity
When stimulated, the sympathetic system of the body causes the heart rate to Increase
QRS Complex Q, R, and S waves
ST Segment End of QRS complex to the beginning of T wave
PR Interval P wave and baseline prior to QRS complex
P Wave Upward small curve
QT Interval QRS complex, ST segment, and T wave
