Commonly Tested Rhythm Strips in NCLEX 2024
Ventricular Rhythm - ANSWER: originate in ventricle or bundle branches, wide QRS,
mostly will not see P wave,fires 20-40 sec, life threatening
Escape - ANSWER: When one electrical node fails another takes over
Ursurpation - ANSWER: to take power from
Premature Ventricular Contraction - ANSWER: beat occurs earlier than the QRS
should have, wide QRS, wide and bizarre look
unifocal PVC - ANSWER: originate from one single ectopic focus in the ventricle and
look alike
multifocal PVC - ANSWER: originate from different sites and they all look different
Bigeminy - ANSWER: every other QRS complex is a PVC
Trigeminy - ANSWER: every third QRS complex is a PVC
Quadrigeminy - ANSWER: every fourth QRS complex is a PVC
Couplet - ANSWER: 2 PVC side by side
V-tach - ANSWER: 3 PVC or more in a row, mostly irregular, rate 100-150, QRS > .12
Torsade De Points - ANSWER: twisting around the baseline, variation of V-tach.
Ideoventricular Rhythm - ANSWER: regular rhythm, HR 20-40, QRS> .12
V- Fib - ANSWER: irregular, wavy baseline, absent P wave, QRS, and PR interval, no
organized activity
Ventricular Asystole - ANSWER: Absent HR, rhythm, P wave, PR interval, and QRS
complex
Pacemakers - ANSWER: electronic devices implanted into or attached to patient
Atrial Rhythms - ANSWER: origin of the electrical impulse originates from
somewhere in the atria, SA node is not in command, may not have a P wave, rapid
rhythms with usurp
Premature Atrial Contraction - ANSWER: Ectopic beat that occurs before the cardiac
cycle should begin, may have a P wave before the early QRS, P wave may be hidden
in the T wave- T wave will look funny
