Cardiac Anatomy and Physiology
This chamber pumps oxygenated blood to the body.
What is the left ventricle?
The EKG Technician can accept this type of patient consent for the EKG procedure.
What is implied consent?
This wave represents atrial depolarization.
What is the P wave?
What should the EKG technician use to remove dirt and oil from the patient's skin prior to electrode placement?
What is an alcohol swab?
This type of artifact is caused by interference from additional electrical devices.
What is AC Interference?
This structure is known as the heart’s natural pacemaker.
What is the SA node?
What should the EKG Technician do if the patient complains of chest pain during a stress test?
What is stop the test and notify the provider?
This complex represents ventricular depolarization.
What is the QRS complex?
What site is most commonly used to assess pulse in an adult patient?
What is the radial artery?
This rhythm is characterized by a sawtooth atrial pattern.
What is atrial flutter?
This valve prevents backflow into the right atrium.
What is the tricuspid valve?
This type of protective device should be worn by the CET when the patient has been diagnosed with tuberculosis.
What is an N95 mask?
This measurement equals the height of the standardization mark.
What is 10mm?
What is 95%?
This shockable rhythm features wide, regular QRS complexes at a fast rate.
What is ventricular tachycardia?
This vessel returns oxygenated blood from the lungs to the heart.
What are the pulmonary veins?
This infection control step is the single most effective way to prevent disease transmission.
What is hand hygiene?
This segment should be isoelectric and is key in identifying ischemia.
What is the ST segment?
When performing an EKG on an 8-month-old patient, the CET would apply this electrode at the fifth intercostal space at the right axillary line.
What is V6?
This interference can be caused by muscle tremors or shivering.
What is somatic tremor artifact?
This part of the conduction system delays the electrical impulse before it reaches the ventricles.
What is the AV node?
How often should the CET disinfect the lead wires?
What is between each patient?
What is the standard speed of paper moving through the electrocardiograph?
What is 25mm/second?
This lead is placed at the 5th intercostal space at the midclavicular line.
What is V4?
This shockable rhythm has no discernible waves and no cardiac output.
What is ventricular fibrillation?
