Introduction to EKG Technology and Applications

During depolarization the cells _________.

• become more negative inside

• remain neutral inside

• become more positive inside

• become less permeable to ions

Define the term 'ambulatory monitoring'.

• 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 monitors are examples.

• A method of monitoring patients only during hospital stays using traditional EKG machines.

• A technique used to measure blood pressure in a clinical setting without patient mobility.

• A type of exercise program designed for patients recovering from heart surgery.

What does EKG stand for?

• Electrocardiogram

• Electrokinetic Gradient

• Electrolytic Kinetics Generator

• Electromagnetic Key Generator

What does a portable EKG machine look like?

• A large, stationary device with multiple screens.

• A small, handheld device with electrodes and a display screen.

• A wristband that monitors heart rate only.

• A smartphone app that tracks physical activity.

Which of the following describes the types of EKG-based tests and their indications?

• Holter monitor for continuous monitoring, stress test for exercise-induced issues, and standard EKG for baseline heart activity.

• Holter monitor for exercise-induced issues, stress test for continuous monitoring, and standard EKG for heart failure.

• Holter monitor for baseline heart activity, stress test for continuous monitoring, and standard EKG for exercise-induced issues.

• Holter monitor for heart failure, stress test for baseline heart activity, and standard EKG for exercise-induced issues.

Define the term 'mobile cardiac telemetry'.

• A type of ambulatory monitor that detects heart rate or rhythm irregularities automatically and transmits data to a healthcare professional when an irregularity occurs.

• A device used for measuring blood pressure in a clinical setting.

• A portable ECG machine that only records heart activity during exercise.

• A smartphone application that tracks daily physical activity and heart rate.

Define the following term: voltage.

• difference in electrical charge.

• a measure of electrical resistance.

• the flow of electric current.

• the potential energy per unit charge.

The portable EKG machine is used to:

• Monitor heart activity

• Measure blood pressure

• Assess lung function

• Evaluate kidney performance

The difference between electrodes, leads, and lead wires is:

• Electrodes are the pathways, leads are sensors, and lead wires connect the machine.

• Electrodes are sensors, leads are the pathways, and lead wires connect electrodes to the machine.

• Electrodes are the machines, leads are sensors, and lead wires connect the pathways.

• Electrodes are connectors, leads are the machines, and lead wires are sensors.

True or False? Electrocardiogram and echocardiogram are different names for the same test.

• True

• False

• Both are the same test

• Neither is a medical test
