second-degree AV block (mobitz II block)
(again no progressive prolongation between the PR interval) -
CORRECT ANSWER-
atrial fibrillation
(rhythm is regularly irregular - ventricular rate is gonna be different from
beat to beat. without any constant pattern, it does not present with any real
P-waves.) - CORRECT ANSWER-
second-degree atrioventricular block (mobitz I block wenckebach)
Ventricular fibrillation
, (Fine - this arrhythmia has no real rhythm at all appears as an electrical
chaos) - CORRECT ANSWER-
Ventricular fibrillation
(Coarse - this arrhythmia is a v-fib, only much more courser and appears as
electrical chaos) - CORRECT ANSWER-
Atrial flutter
(this pattern has a recognizable "sawtooth-pattern" in between the
ventricular contractions look for the 3:1) - CORRECT ANSWER-
Second-degree atrioventricular block (Mobitz II block)
(In this arrhythmia, you will have regular contractions with a QRS & P-
Wave without the progressive prolongation between the PR-interval
generally seen in Mobitz I block, followed by a sudden dropped beat) -
CORRECT ANSWER-
sinus bradycardia
(this rhythm is significantly slower, but is normal as it contains P, QRS and
T waves seen in normal sinus with just a slower rate) - CORRECT
ANSWER-
