35 elaborated questions and
answers 2024
2nd Degree Heart Block (Mobitz II) - answer ✅✅Rare, 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) - answer
✅✅Progressively longer PR interval until the P wave is not followed
by a QPR
3rd degree heart block - answer ✅✅no obvious correlation between
p and qrs, need pace maker
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
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"
