EKG EXPECTED QUESTIONS WITH VERIFIED ANSWERS
Question 1.
EKG or ECG stands for:
ANSWER
electrocardiogram
Question 2.
What can an EKG detect?
ANSWER
cardiac arrhythmia or dysrhythmia, ischemia, electrolyte imbalance, effects of cardiac medications,
damage caused by an MI
Question 3.
Define arrhythmia
ANSWER
abnormal cardiac rhythm (think a= without, without rhythm)
Question 4.
Define ischemia
ANSWER
lack of blood supply
Question 5.
What is the electrical pathway of the heart's conduction system?
ANSWER
SA node->AV node->Bundle of His->Right and Left Bundle Branches->Purkinje fibers
Question 6.
When the SA node is stimulated, what mechanical action happens in the heart?
ANSWER
Atria contract
1
, Question 7.
What has to happen for the ventricles to contract?
ANSWER
Electrical conduction has to pass through the AV node, down the Bundle of His, through the right and
left bundle branches, into the purkinje fibers. Once they reach the Purkinje fibers, then the ventricles
will contract.
Question 8.
Electrodes
ANSWER
sticky skin sensors that attach to the patient
Question 9.
What is the purpose of the gel on the electrodes?
ANSWER
to read the heart's electricity and to amplify the waveforms
Question 10.
EKG machine is also called an:
ANSWER
electrocardiograph
Question 11.
Name the 2 types of EKG machines:
ANSWER
Single channel and multichannel
Question 12.
When we do an EKG we are looking at the heart from :
an EKG?
ANSWER
12 different points of view or angles
Question 13.
What is an amplifier?
ANSWER
Magnifies the heart's electrical signal so it can be recorded.
