EKG CHAPTER 5 TERMS EXAM 2025
QUESTIONS AND ANSWERS
Depolarization - ....ANSWER ...-An electrical change in the heart in which
the voltage of the cells becomes more positive and cells contract.
Repolarization - ....ANSWER ...-An electrical change in the heart in which
the voltage of the cells becomes more negative and the cells relax.
Electrodes - ....ANSWER ...-In EKG technology, pads that conduct
electricity and are connected to the patient's body and to electrode cables to
conduct electrical signals from the heart to the EKG machine.
Lead Wires - ....ANSWER ...-Wires that connect electrodes placed on a
patient's body to an EKG machine; also called lead wires or electrode wires.
Leads - ....ANSWER ...-In an EKG, the imaginary line between two
electrodes attached to the patient; each lead on can produce a different EKG
tracing and a different view of the heart's electrical activity.

, EKG Tracing - ....ANSWER ...-Record of the electrical activity of a patient's
heart during an electrocardiogram (EKG) as recorded by an EKG machine; also
called EKG strip or rhythm strip.
Echocardiogram (ECHO) - ....ANSWER ...-A test that uses sound waves to
visualize the heart; provides information about the mechanical function of the
heart.
Voltage - ....ANSWER ...-Difference in electrical charge.
Telemetry - ....ANSWER ...-An application of EKG technology that allows
continual monitoring of a patient's heart rate and rhythm; often used in an
emergency room or hospital setting.
Ambulatory Monitoring - ....ANSWER ...-A type of EKG technology that
can record or monitor a patient's heart rate and rhythm over an extended period
while the patient continues with normal life; Holter, event, and mobile telemetry
monitor are examples.
Holter Monitor - ....ANSWER ...-A type of ambulatory monitor that allows a
doctor to evaluate heart rate and rhythm over an extended period of time (usually
24-48 hours) while the patient continues with normal life.
