ECG SHARP EXAM REVIEW
(QUESTIONS) EXAM WITH COMPLETE
SOLUTIONS
Layers of heart -ANSepicardium, myocardium, endocardium
Electrical ions responsible for depolarization and repolarization of the heart -
ANSSodium, calcium, and potassium
Negative Deflection -ANSthe downward presentation of waveforms on the EKG tracing
that is located below the isoelectric line
Postive Deflection -ANSthe portion of waveforms in an EKG tracing located above the
isoelectric line
Biphasic Deflection -ANSboth positive and negative
St Elevation -ANSindicates myocardial infarction (STEMI)
ST Depression -ANSmyocardial ischemia
How much is one box on the ECG -ANS0.04 sec
SA Node -ANSpacemaker of the heart
AV Node -ANSrelays electrical impulses from atria into ventricles
Purkinje fibers -ANSfibers in the ventricles that transmit impulses to the right and left
ventricles, causing them to contract
What do frequent PACs mean? -ANSCan indicated stroke or higher mortality
Treatment for asystole -ANSCPR, epinephrine, atropine
Treatment for Atrial fibrillation -ANSAnticoagulation, rate control, cardioversion
Treatment for Symptomatic Junctional Rhythm -ANSAtropine
Medication for V-Tach -ANSAmiodarone
R on T Phenomenon -ANSpremature ventricular contraction whose R wave falls on the
T wave of the preceding complex
