APEX EKG CERTIFICATION EVALUATION
TEST 2026 FULL QUESTIONS AND
ANSWERS EXPERT VERIFIED

●● Conduction velocities if cardiac conduction pathway from slowest to
fastest:.
Answer: AV node
SA node
Myocardial muscle cells
HIS bundle
Bundle branches
Purkinje fibers


●● Match each phase of the ventricular action potential to its
corresponding component on the EKG waveform:


Phase 0
Phase 2
Phase 3


T wave
QT interval

,QRS complex.
Answer: Phase 0- QRS
phase 2- QT interval
Phase 3- T wave


There are 5 phases of ventricular action potential:


0= rapid depolarization (QRS) - Na IN
1= initial repolarization(QRS) - Cl in/K+ OUT
2= plateau phase (QT interval)-Ca IN/K out
3= final repolarization (T wave)- K+ OUT
4= resting phase (T to QRS)- K+ leak


●● Key components of the EKG:.
Answer: P wave- atrial depolarization begins
PR interval- atrial depolarization complete
QRS- atrial repolarization + ventricular depolarization
ST segment- ventricular depolarization complete
T wave- ventricular repolarization begins


●● Match each disease with the EKG abnormality that it is most likely
to cause:

, Hypokalemia
WPW
Pericarditis
Intracranial hemorrhage




PR interval depression
U wave
Peaked T wave
Delta wave.
Answer: Hypokalemia- U wave
WPW- Delta wave
Pericarditis- PR interval depression
Intracranial hemorrhage- Peaked T wave


●● Q waves suggest myocardial infarction if:.
Answer: Amplitude is greater than 1/3 of R wave
Duration is greater than 0.04 secs
Depth is greater than 1mm


●● Peaked T wave causes.
