Relias Dysrhythmia Basic
A Test – 2025/2026 –
Complete Questions and
Correct Answers
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 -<40
*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
Failure to capture (pacemaker) - ANSWER -
failure to sense (pacemaker) - ANSWER -
Atrial paced rhythm - ANSWER -spike before P wave
Ventricular paced rhythm - ANSWER -ventricular contractions which occur in cases of complete heart
block.
normal sinus rhythm - ANSWER -heart rhythm originating in the sinoatrial node with a rate in
patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - ANSWER -Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
