RCES EXAM QUESTIONS WITH CORRECT
ANSWERS
What is ARVD and when does it occur? - CORRECT ANSWER✔✔-Arrhythmogenic
| | | | | | | | | | |
Right Ventricular dysplasia; occurs when the RV myocardium is replaced by fatty
| | | | | | | | | | | |
and fibrotic tissue
| |
What are afterdepolarizations? - CORRECT ANSWER✔✔-Abnormal secondary
| | | | | | |
voltage depolarizations during the cardiac action potential
| | | | | |
What are the two types of afterdepolarizations? - CORRECT ANSWER✔✔-EADs
| | | | | | | | | |
(early after depolarizations) and DADs (delayed afterdepolarizations
| | | | | |
What does the QT interval represent? - CORRECT ANSWER✔✔-ventricular
| | | | | | | | |
depolarization and repolarization | |
What is antedromic conduction? - CORRECT ANSWER✔✔-Antedromic conduction
| | | | | | |
is a type of AVRT in which the impulse travels down the pathway and up the AV
| | | | | | | | | | | | | | | | | |
node--seen in WPW | |
What is orthodromic conduction? - CORRECT ANSWER✔✔-A type of AVRT in
| | | | | | | | | | |
which the impulse travels down the AV node and up the pathway--this type of
| | | | | | | | | | | | | |
conduction is more common | | |
, What 3 criteria are needed to sustain a reentry circuit? - CORRECT ANSWER✔✔-
| | | | | | | | | | | |
1.) Parallel pathways that are connected proximally and distally, forming an
| | | | | | | | | | |
electrical circuit 2.) One of the pathways needs a refractory period that's
| | | | | | | | | | | |
substantially longer than the refractory period of the other 3.) The pathway with
| | | | | | | | | | | | |
the shorter refractory period must conduct electrical impulse more slowly than
| | | | | | | | | | |
the other pathway
| |
What is a normal AH interval? - CORRECT ANSWER✔✔-50-140ms
| | | | | | | |
What is a normal HV interval? - CORRECT ANSWER✔✔-35-55ms
| | | | | | | |
What is a normal HBE? - CORRECT ANSWER✔✔-<30ms
| | | | | | |
What is a normal PA interval? - CORRECT ANSWER✔✔-25-55ms
| | | | | | | |
What is a normal QTc? - CORRECT ANSWER✔✔-For men: <450, For women <470
| | | | | | | | | | | |
What is a normal QRS interval? - CORRECT ANSWER✔✔-<120ms
| | | | | | | |
What is Ohm's Law? - CORRECT ANSWER✔✔-V = IR; V= voltage measured in
| | | | | | | | | | | | |
volts, I= current measured in amps and R= resistance ohms
| | | | | | | | |
What is the most likely rhythm is capture beats or fusion beats are seen on the
| | | | | | | | | | | | | | | |
EKG? - CORRECT ANSWER✔✔-Ventricular Tachycardia because both beats
| | | | | | | |
demonstrate AV dissociation | |
