What is ARVD and when does it Arrhythmogenic Right Ventricular dysplasia; occurs
occur? when the RV myocardium is replaced by fatty and
fibrotic tissue
What are afterdepolarizations? Abnormal secondary voltage depolarizations
during the cardiac action potential
What are the two types of EADs (early after depolarizations) and DADs
afterdepolarizations? (delayed afterdepolarizations
What does the QT interval ventricular depolarization and repolarization
represent?
What is antedromic conduction? 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? 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 1.) Parallel pathways that are connected proximally
a reentry circuit? 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? 50-140ms
What is a normal HV interval? 35-55ms
What is a normal HBE? <30ms
What is a normal PA interval? 25-55ms
What is a normal QTc? For men: <450, For women <470
What is a normal QRS interval? <120ms
What is Ohm's Law? V = IR; V= voltage measured in volts, I= current
measured in amps and R= resistance ohms
What is the most likely rhythm is Ventricular Tachycardia because both beats
capture beats or fusion beats are demonstrate AV dissociation
seen on the EKG?
When do EADs occur? EADs are seen in phase 2 or phase 3 of the action
potential
