b. The QRS complexes are regular.
c. The P-R relationship varies
d. The atrial rate is constant.
e. 2:1 or 3:1 conduction is not present.
◉ a. Bundle Branches / Purkinje System
c. Ventricular Myocardium
d. Atrial myocardium. Answer: Which of the following tissues
depolarize primarily due to rapid inward sodium currents. MORE
THAN ONE ANSWER IS EXPECTED.
a. Bundle Branches / Purkinje System
b. Sinus Node
c. Ventricular Myocardium
,d. Atrial myocardium
e. AV Node
◉ c. Type II Second Degree AV Block.. Answer: Examine the ECG
below and identify the correct diagnosis.
a. Sinus Rhythm with 3:2 Wenckebach.
b. Type I Second Degree AV Block.
c. Type II Second Degree AV Block.
d. Non-conducted Atrial Trigeminy.
e. High Grade Second Degree AV Block.
◉ d. Type I Second Degree AV Block.. Answer: Select the correct
diagnosis to describe the rhythm below.
a. 4:3 Wenckebach.
b. Non-conducted Atrial Trigeminy.
c. Type II Second Degree AV Block.
d. Type I Second Degree AV Block.
e. Sinus Rhythm with marked Sinus Arrhythmia.
,◉ d. The bundle branch is only blocked under certain conditions,
such as during a rapid heart rate or with premature beats.. Answer:
A "Functional" Bundle Branch Block means which of the following:
a. The branch is blocked but it nevertheless functions normally.
b. The bundle branch block is related to the presence of poor left
ventricular function.
c. The aberrancy is due to AV node dysfunction.
d. The bundle branch is only blocked under certain conditions, such
as during a rapid heart rate or with premature beats.
e. The QRS duration is less than 120 msec.
◉ a. The patient has a permanent pacemaker.. Answer: What is the
reason for the IVCD in the ECG below.
a. The patient has a permanent pacemaker.
b. The QRS isn't wide, you're just imagining it.
c. The patient has a bundle branch block.
d. The patient has slow ventricular tachycardia.
e. The patient has WPW Syndrome.
◉ b. Conduction delay within the AV Node.. Answer: Which of the
following would NOT result in widening of the QRS complex:
, a. A Left Bundle Branch Block
b. Conduction delay within the AV Node.
c. Right ventricular pacing.
d. A Right Bundle Branch Block.
e. Pre-excitation due to an accessory pathway.
◉ e. The QRS is wide and the PR is short because of pre-excitation.
The blue arrow is the delta wave.. Answer: Looking at the ECG below,
what is going on?
a. The QRS is only a little wide because of a non-specific IVCD,
marked with the blue arrow.
b. There is no blue arrow. This is a trick question.
c. There is a permanent pacemaker. The blue arrow points to the
pacing spike.
d. The QRS is wide and the PR is normal. It's a Left Bundle Branch
Block with a slurred upstroke.
e. The QRS is wide and the PR is short because of pre-excitation. The
blue arrow is the delta wave.
◉ a. Left Bundle Branch Block Correct
