RELIAS DYSRHYTHMIA BASIC A & B 35TESTBANK QUESTIONS WITH ANSWERS
LATEST 2024 100 % COMPLETE
2nd Degree Heart Block (Mobitz II) - ansRare, but more serious
Sudden appearance of a nonconducted P-wave
P-waves are nl, but some aren't followed by a QRS complex
PR & RR intervals are constant
2nd degree heart block type 1 (Wenkebach) - ansProgressively longer PR interval until
the P wave is not followed by a QPR
3rd degree heart block - ansno obvious correlation between p and qrs, need pace
maker
Accelerated Idioventricular Rhythm - ansRate: 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 - ansabsence of contractions of the heart
Atrial Fibrillation (A-Fib) - ansan irregular and often very fast heart rate originating from
abnormal conduction in the atria
Atrial Flutter - ansirregular beating of the atria; often described as "a-flutter with 2 to 1
block or 3 to 1 block"
Atrial paced rhythm - ansspike before P wave
Bigeminy PVC - ansevery other beat is a PVC
Failure to capture (pacemaker) - ans
failure to sense (pacemaker) - ans
First degree heart block - ansatrioventricular (AV) block in which the atrial electrical
impulses are delayed by a fraction of a second before being conducted to the ventricles
Idioventricular Rhythm - ans<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)
