Basic Dysrhythmia-Relias Latest Already Passed Graded A+ 2nd Degree Heart Block (Mobitz II) - Correct AnswerRare, 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) - Correct AnswerProgressively longer PR interval until the P wave is not followed by a QPR
3rd degree heart block - Correct Answerno obvious correlation between p and qrs, need pace maker
Accelerated Idioventricular Rhythm - Correct AnswerRate: 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 - Correct Answerabsence of contractions of the heart
Atrial Fibrillation (A-Fib) - Correct Answeran irregular and often very fast heart rate originating from abnormal conduction in the atria
Atrial Flutter - Correct Answerirregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block"
Atrial paced rhythm - Correct Answerspike before P wave
Bigeminy PVC - Correct Answerevery other beat is a PVC
Failure to capture (pacemaker) - Correct Answer
failure to sense (pacemaker) - Correct Answer
First degree heart block - Correct Answeratrioventricular (AV) block in which the atrial electrical impulses are delayed by a fraction of a second before being conducted to the ventricles
Idioventricular Rhythm - Correct Answer<40
