APEX EKG TEST QUESTIONS AND ANSWERS 2025

APEX EKG TEST LATEST

Supraventricular Tachycardia (SVT)
Regularity: atrial and ventricular rate regular
Rate: greater than 160 beats per minute, (can be 200 beats per
minute or more)
P wave: abnormal, small and upright, may be hidden in QRS if
rate is very fast
PRI : less than 0.12 seconds, if present
QRS: typically less than 0.06 - 0.08 seconds, very narrow
QTI: indiscernible
T wave: indiscernible




Paroxysmal Supraventricular Tachycardia (PSVT)
Paroxysmal refers to a rhythm that starts and stops suddenly
Premature Junctional Contractions
Regularity: underlying rate is regular except for early beat
Rate: determined by the underlying rhythm
P wave: upright, smooth, round and uniform shape, EXCEPT for
the early beat, it will be inverted before or after the QRS or
missing
PRI : 0.12 to 0.20 seconds normal in the underlying rhythm,
<0.12 seconds in the early if it precedes the QRS

QRS: 0.06 to 0.10 seconds and all are uniform
QTI: 0.36 to 0.46 seconds
T wave: upright, smooth and round uniform shape




Junctional Rhythm
Regularity: atrial and ventricular rate is regular
Rate: 40 to 60 beats per minute
P wave: inverted or absent, may be before, within or after the
QRS
PRI : less than 0.12 seconds if the P wave precedes the QRS
complex
QRS: 0.06 to 0.10 seconds and usually normal
QTI: 0.36 to 0.46 seconds
T wave: usually normal, upright, smooth and round uniform
shape

Accelerated Junctional Rhythm
Regularity: atrial and ventricular rate is regular
Rate: > 60 but less than 100
P wave: inverted or absent, may be before, within or after the
QRS
PRI : less than 0.12 seconds if the P wave precedes the QRS
complex
QRS: 0.06 to 0.10 seconds and usually normal
QTI: 0.36 to 0.46 seconds
T wave: usually normal, upright, smooth and round uniform
shape
