EKG & Cardio

unwanted external event occurring in an EKG tracing not associated with the heart function artifact
the machine that records an electrocardiogram: electrocardiograph
also known as gain is the degree of change in an EKG tracing, it is represented by the vertical axis amplitude
Recording of electrical current involving both a positive and negative pole bipolar
recording of one location or one pole is: unipolar
A unipolar recording that requires assisting in magnifying the tracing by drawing from other poles is: augmented
Located on the chest in front of the heart precordial
this is the first wave in the cardiac cycle representing atria depolarization P Wave
Asystole: contraction depolarization
the second wave in the cardiac cycle representing ventricular depolarization is: QRS wave
Systole: relaxation is: Repolarization
the third wave in the cardiac cycle representing ventricular repolarization T wave
A collection of fibers that conduct the electrical impulses from the AV node to the ventricular septum is: bundle of HIS
the finger like projections that spread through the ventricular muscle and initiate ventricular contraction are: Purkinje fibers
The length of time from the beginning of atrial depolarization to the beginning of ventricular depolarization is: P R interval
The length of time from the beginning of the ventricular depolarization to ventricular depolarization is: QT interval
The process of recording an electrocardiogram is: electrocardiography
The universally acceptable speed of the tracing and gain (height) used for accurate interpretation of the tracing is: standardization
Muscle movement causing irregular spike in an EKG tracing is: somatic tremor
60 cycle interference; an artifact in the EKG tracing caused by electrical interference is: alternating current AC interference
Inconsistency in the baseline location on the EKG tracing likely caused by poor lead contact or skin placement is: wandering baseline
A break in the tracing usually caused by a disconnected or broken lead is: interrupted baseline
Also known as dysrhythmia: a change from a normal EKG rhythm: arrhythmia
The natural pacemaker of the heart located in the upper right atrium is: sinoatrial node, SA Node
An upward curvature of waves in an EKG tracing is: positive deflection
A downward curvature of waves in an EKG tracing is: negative deflection
The secondary pacemaker located at the junction of the atria and ventricles is the: Atrioventricular node, AV node
Often referred to as Holter monitoring: an EKG conducted over a period of time while the patient resumes normal activities is called: ambulatory monitoring
The wall muscle is called the septum
The right side of the heart carries: deoxygenated blood
The top chambers are called atrium, atria
The bottom chambers of the heart are called ventricles
What are the 3 layers of the heart called endocardium, myocardium, epicardium
What are the 3 types of circulation coronary, pulmonary, systemic
Where does gas exchange take place in the capillaries
What do veins have that arteries do not have? valves
Arteries have a: pulse
When blood collects under the skin it forms a hematoma
What vein is located in the middle of the forearm median cubital
________ is located on the outer side of the arm yet harder to palpate cephalic
This vein is located in the inner arm its the third choice and lays close to the median nerve and brachial artery basilic vein
These cells are biconcave and carry hemoglobin erythrocytes
_________ means they can pass through capillaries' thin walls diapedesis
cells surrounding and destroying (eating) the foreign substances thru a process known as: phagocytosis
3 types of lymphoid cells are: T lymphocytes, B lymphocytes, and natural killer (NK) cells
Cells that have a nucleus that is segmented into 2 or more lobes are: polymorphonuclear
Cells with single lobed nucleus are: mononuclear
________ Cells have 3-4 lobes, neutral staining, tan, lavender, or pink,60-70%, and engulf bacteria Neutrophils
_________ Cells are bilobed nucleus and cytoplasmic granules that stain orange-red, 1-4%, and destroy parasites Eosinophils
________ cells a bilobed nucleus and cytoplasmic granules that stain deep blue and may appear black, 0-1%, increase with chronic inflammation and during healing from infection. Basophils
________ have large kidney shaped nuclei with cytoplasmic granules, 2-6%, Are the largest WBC's, increase during chronic infections such as tuberculosis Monocytes
_______ have round nucleus with a minimum amount of cytoplasm, may be B, T, or NK cells, 20-30%, increase with viral infections Lymphocytes
Another name for platelets thrombocytes
Liquid portion of whole blood plasma
Liquid portion of clotted blood serum
