Critical Care EKG and Cardiac Rhythm Review for Nursing Students
Critical Care EKG and Cardiac Rhythm Review for Nursing Students
Study online at https://quizlet.com/_jq6429
1. Electrocardiogram A painless test that provides an image tracing the electrical current within the
heart
2. Action Potential Cardiac muscle's ability to respond to a stimulus and generate an electrical
impulse
3. Excitability The cell responds to almost any impulse, even if weak
4. Conductivity Cardiac muscle's ability to transfer the action potential from muscle cell to
muscle cell
5. Contractility Cardiac muscle's ability to convert an electrical signal into an action
6. Automaticity Cardiac muscle's ability to contract at regular intervals, also known as 'rhythmic-
ity'
7. Node Mass of tissue that can create or send a stimulus
8. Chamber Enclosed space or cavity within the heart in which blood collects
9. Valve Controls and directs the flow of blood through the circulatory system
10. Waves, Complexes, Components of the EKG tracing
Intervals
11. Rate Speed, used to reference how many times per minute an event occurs within
the heart
12. Depolarization Change in electrical charge on the surface of a cell in response to a stimulus
13. Repolarization Slower process, the cell membrane is returning to its resting state (K+ is moving
out of the cell)
