APEX EKG TEST ASSURED SUCCESS EXAM 100% VERIFIED
QUESTIONS AND DETAILED ANSWERS GRADED A+
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
Junctional tachycardia
Regularity: atrial and ventricular rate is regular
Rate: >100 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
, Premature ventricular contractions (pvcs)
Regularity: atrial rate regular, underlying ventricular rate is
regular except for the interrupting early beat
Rate: determined by the underlying rhythm
P wave: upright, smooth, round and uniform shape, except at
the early beat it will be absent
Pri : 0.12 to 0.20 seconds except for early beat
Qrs: 0.06 to 0.10 seconds or normal, for the early beat its wide
and bizarre
Qti: 0.36 to 0.46 seconds for normal beats
T wave: normal except for early beats
Ventricular tachycardia (lethal)
Regularity: usually regular
Rate: 140 to 250 beats per minute
P wave: usually none seen, but dissociated from the qrs if
present
Pri : none
Qrs: > 0.12 seconds, wide and bizarre, tombstone like
Qti: unable to determine
T wave: absent, usually buried in the qrs
