The horizontal axis of the EKG graph paper measures what concept? - answer Time
Which intervals are traditionally measured to be able to evaluate on an
electrocardiogram? SATA - answerPR interval
QRS
What is the difference between sinus rhythm and sinus bradycardia? – answer They
have different rates
If the R to R ratios in an EKG are inconsistent , what is true about the EKG strip? -
answer The rhythm is irregular
What is the correct order of normal electrical activity in the cardiac cycle? – answer SA
node, AV node, bundle branches, purkinje fibers
Correctly identify the following EKG strip – answer Sinus rhythm
Correctly identify the following 6 second EKG strip - answer Atrial fibrillation (No P
wave!)
A patient's pacemaker is firing electricity at the appropriate times, but the EKG shows a
flat line with no EKG complex after each pacer spike.
What pacemaker problem does this describe? - answerFailure to capture
Which of the following is considered a "lethal dysrhythmia" ? - answer3rd Degree AV
Block
Identify the following EKG strip - answerVentricular Fibrillation (No QRS complex!)
The BEST way to assess if a patient is hypovolemic would be to measure... -
answerThe pressure in the right atrium
How would you measure how well a patient's heart is SQUEEZING? - answerMeasure
the percentage of blood that leaves the ventricle after each beat
Which of the following is the most accurate reflection of blood being pumped out of the
heart relative to the patient's size? - answerCardiac Index (CI)
Which of the following reflects a percentage of blood leaving the left ventricle with with
one beat? - answerEjection Fraction (EF)
