CHAPTER 49 ELECTROCARDIOGRAPHY AND PULMONARY FUNCTION TESTING Worksheet

______________________________________ is the process by which a graphic pattern is created from the electrical impulses generated within the pumping heart.
___________________________ is the condition of having two separate poles, one of which is positive and the other negative.
An artifact called a _________________________ is identified by a shift in the baseline from the center position for that lead. Causes include muscle movement or improper application of electrodes which are too loose or incorrectly placed.
A __________________________ is exercise electrocardiography which assesses the heart’s conduction system during exercise (with a treadmill bicycle, or stair-stepper) when the demand for oxygen increases.
Electrodes are placed on _________________________ areas of the body.
_______________________________________ delivers the ability to view the moving heart.
______________________________________ is a noninvasive test that measures the saturation of oxygen in a patient’s arterial blood.
Readings less than 95% indicate ___________________________.
A ____________________________________________ to evaluates a patient’s lung volume and capacity.
______________________________ is a test used to measure breathing capacity.
__________________________________________ is the greatest volume of air that can be expelled when a person performs rapid, forced expiration.
An instrument called a ____________________________ measures the air taken in by and expelled from the lungs.
______________________________ uses a special type of ultrasound to look at blood flow through the heart.
Cardiac dysrhythmias or arrhythmias are ____________________________ in the heart rhythm.
An artifact called ___________________________________ interference happens when the electrocardiograph picks up electrical current from another piece of nearby electrical equipment.
An artifact called _____________________________ interference happens because of muscle movement during shifting of position, tremors, or talking.
____________________________ is a natural occurrence of an electrical impulse that initiates a chain reaction resulting in contraction.
The resting period of the heart occurs during ____________________________ .
