RELIAS DYSRHYTHMIA BASIC TEST
COMPREHENSIVE EXAM 2026
◉ Sinus Arrhythmia. Answer: Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
◉ Sinus Bradycardia. Answer: <60
normal sinus rhythm
◉ Sinus Tachycardia. Answer: >100 (100-150)
normal sinus rhythm
◉ Premature Atrial Contraction (PAC). Answer: Heart Rate: Depends
on underlying rhythm
Regularity: Interrupts the regularity of underlying rhythm
P-Wave: can be flattened, notched, or unusual. May be hidden within
the T wave
PRI: measures between .12-.20 seconds and can be prolonged; can
be different from other complexes
QRS: <.12 seconds

RELIAS DYSRHYTHMIA BASIC TEST

COMPREHENSIVE EXAM 2026

◉ Sinus Arrhythmia. Answer: Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) ◉ Sinus Bradycardia. Answer: < normal sinus rhythm ◉ Sinus Tachycardia. Answer: >100 (100-150) normal sinus rhythm ◉ Premature Atrial Contraction (PAC). Answer: Heart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave PRI: measures between .12-.20 seconds and can be prolonged; can be different from other complexes QRS: <.12 seconds

◉ Sinus Arrest/Pause. Answer: - SA node doesn't fire

  • notice absence of P-wave for a complete cycle (a missed cycle) length of pause ≠ multiple of normal rate (block) ◉ Atrial Fibrillation (A-Fib). Answer: an irregular and often very fast heart rate originating from abnormal conduction in the atria ◉ Atrial Flutter. Answer: irregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block" ◉ Junctional Rhythm. Answer: 40-60 Regular!
  • impulse from AV node w/ retro/antegrade transmission
  • P wave often inverted/buried/follow QRS
  • slow rate
  • narrow QRS (not wide like ventricular) ◉ Junctional Tachycardia. Answer: >60 bpm (ms. K; 150-250)
  • KEY: will be regular (consistent)
  • AV junction produces a rapid sequence of QRS-T cycles
  • p-wave often inverted/buried/follow QRS

◉ 3rd degree heart block. Answer: no obvious correlation between p and qrs, need pace maker ◉ premature ventricular contraction (PVC). Answer: a ventricular contraction preceding the normal impulse initiated by the SA node (pacemaker) ◉ Bigeminy PVC. Answer: every other beat is a PVC ◉ PVC couplets. Answer: PVC occurring in pairs, no adequate C.O. when this occurs ◉ monomorphic ventricular tachycardia. Answer: presents with wide QRS complexes of a common shape. ◉ Torsades de pointes. Answer: Rate: 120 - 200 usually P wave: Obscured by ventricular waves QRS: Wide QRS - "Twisting of the Points" Conduction: Ventricular only Rhythm: Slightly irregular ◉ Ventricular fibrillation (V-fib). Answer: abnormal heart rhythm which results in quivering of ventricles

◉ Idioventricular Rhythm. Answer: < looks like vtach but slow

  • no P waves (from vent foci)
  • Wide QRS (serious, death like rhythm)
  • called "dying heart" rhythm...occasional ventric beat b4 death (asystole) ◉ Accelerated Idioventricular Rhythm. Answer: Rate: 50 - 100 usually (usually slow) P wave: Obscured by ventricular waves (occur during ventricular contraction) - SA node slower than faster ventricular pacing than should be QRS: Wide QRS Conduction: Ventricular only Rhythm: Regular
  • benign rhythm that is sometimes seen during acute MI or early after reperfusion. - Rarely sustained, does not progress to vfib, rarely requires treatment ◉ asystole. Answer: absence of contractions of the heart
