Blood vessels
This short coronary artery bifurcates into the left circumflex (LCx) and left anterior descending (LAD) arteries.
What is the left main coronary artery (LMCA)?
This structure protects and stabilizes the heart while providing lubrication between the heart and surrounding chest organs.
What is the percardium?
This structure lies just below the AV node, where the AV node and bundle of His meet.
What is the AV junction?
What should be removed before an EKG if it may interfere with electrode placement or touch the lead wires?
What is Jewelry (such as bracelets and necklaces)?
This blood pressure measurement is recorded when the last last sound disappears completely.
What is diastolic pressure?
This is the largest artery in the human body and carries oxygenated blood away from the heart.
What is the aorta?
This smooth inner layer of the heart protects its surfaces and helps facilitate blood flow through the heart
What is the endocardium?
This EKG wave represents depolarization of the atria, beginning with the right atrium and followed by the left.
What is the P wave?
What should be done to prepare the skin for proper electrode contact?
What is hair clipping or shaving?
Located on the thumb side of the wrist, this pulse site is the most commonly used location for measuring an adult’s pulse.
What is the radial pulse?
These are the only arteries that carry deoxygenated blood from the right ventricle to the lungs.
What are the pulmonary arteries?
This valve lies between the right ventricle and the pulmonary arteries.
What is the pulmonary valve?
This EKG interval represents the time for an electrical impulse to travel from the atria through the AV node to the ventricles.
What is the PR interval?
What reactions should a patient report to the EKG technician if it occurs at the electrode sites?
What is swelling,itching or redness of the skin?
This blood pressure measurement is recorded when the first sharp tapping sound is heard.
What is systolic pressure?
This coronary artery supplies blood to the SA node and AV node.
What is the right coronary artery (RCA)?
These two heart valves are classified as semilunar valves based on their shape.
What are the aortic and pulmonary valves?
This EKG component represents ventricular depolarization.
What is the QRS complex?
The three sbstances that patients should avoid at least 3 hours prior to a stress test
What are caffeine, tobacco, and alcohol?
Located in the neck just below the jawbone, this pulse site is commonly used during emergency procedures.
What is the carotid pulse?
These arteries supply oxygenated blood to the heart muscle (myocardium).
What are the coronary arteries?
These valves, the tricuspid and bicuspid (mitral), are located between the atria and ventricles.
What are the atrioventricular (AV) valves?
This wave on the EKG represents ventricular repolarization.
What is the T wave?
During this type of cardiac monitoring test, patients should keep a journal recording the date, time, duration, and symptoms they experience.
What is a Holter Monitor?
Located on the inside of the upper arm, this pulse site is commonly used to measure a pulse in children.
What is the brachial pulse?
