Medical Terminology
What kind of arteries carry blood to the lungs?
What are the pulmonary arteries?
The process by which a graphic pattern is created from the electrical impulses generated in the heart as it pumps.
What is electrocardiography?
Poor skin preparation due to lotion or cream, dangling wires, patient movement with breathing, or improper application of electrodes can cause this.
What is wandering baseline?
This position should be used for a patient that is uncomfortable lying flat on the examining table for an ECG test.
What is the Fowler's position?
Electrical impulse sensors used to obtain an electrocardiogram.
What are electrodes?
The muscle layer of the heart.
What is myocardium?
A life-threatening dysrhythmia results in no cardiac input.
What is ventricular fibrillation?
The 12 different views recorded on an electrocardiogram that are produced by the electrical activity of the heart.
What are leads?
A precordial electrode located by counting to the fourth intercostal space to the right of the sternum.
What is V1?
Results in a flat line on the ECG training.
What is detached/loose wire?
Due to lack of oxygen, death of the heart tissue can occur.
What is Myocardial Infarction?
A membrane that covers the outer layer of the heart.
What is the pericardium?
A precordial electrode located by counting to the fourth intercostal space to the left of the sternum.
What is V2?
An erroneous mark or defect that may appear on an ECG strip.
What are artifacts?
A precordial electrode placed in the fifth intercostal space, where it intersects an imaginary line drawn straight down the middle of the clavicle.
What is V4?
The narrowing of arteries.
What is arteriostenosis?
The instrument that measures and displays the electrical impulses responsible for the cardiac cycle.
What is an electrocardiograph?
The part of the limbs that would be the best choice for application of limb leads.
What are fleshy portions?
When preparing the room and equipment for an electrocardiogram, the MA should do this.
What is selecting a room away from all other electrical equipment?
Encouraging patients to ask questions and verbalize concerns to alleviate anxiety about having this procedure.
What is electrocardiography?
The amount of pressure against the arterial walls during ventricular contractions.
What is systole?
A record (printout) of the waves of electrical impulses responsible for the cardiac cycle.
What is an electrocardiogram?
A precordial electrode placed in the fifth intercostal space, directly below the middle of the armpit?
