Ablation is most commonly performed with this type of energy
What is radiofrequency
100
A minute contains this many milliseconds
What is 60,000
100
This is a reentrant circuit using pathways of the AV node both antegrade and retrograde
What is AVNRT
100
Atrial fibrillation is believed to originate in these left atrial structures
What are the pulmonary veins
200
This structure is located at the junction of the RA and SVC
What is the sinus node
200
True or false: The hottest spot is typically 1 or more millimeters into the tissue when using RF
What is True
200
This catheter is placed just across the tricuspid valve and allows us to evaluate the AV node
What is the His catheter
200
WPW pattern is indicated by this type of wave seen on ECG representing ventricular preexcitation
What is a delta wave
200
This is a potential complication of all EP studies resulting from catheter perforation and collection of fluid in the pericardial sac
What is cardiac tamponade
300
The coronary sinus catheter provides information for these two cardiac chambers
What is the left atrium and the left ventricle
300
At 100 degrees Celcius, you might hear this noise resulting from water vaporization within the tissue
What is a steam pop
300
This is the normal range for an HV interval
What is 25-55ms
300
This is the most common mechanism for SVT
What is reentry
300
This type of accessory pathway conducts only retrograde and cannot be seen in sinus rhythm on ECG
What is a concealed accessory pathway
400
This standard ECG lead uses right arm as "negative" and left leg as "positive
What is lead II
400
This type of catheter provides local cooling and allows for larger, deeper lesions
What is an irrigated tip catheter
400
An atrial extrastimulus not followed by a His signal or a ventricular signal represents this refractory period
What is AVNERP
400
This is the most common site for idiopathic VT
What is the RVOT
400
This Class III antiarrhythmic is used to treat AT or VT, takes several weeks or a large loading dose to take effect, and has a high incidence of side effects...however is very effective!
What is Amiodarone
500
These ECG leads are referred to as "inferior leads" and provide useful information about the top to bottom directionality of depolarizations
What are leads II, III, and AVF
500
This type of heat (resistive, conductive, or convection) accounts for most of the lesion size
What is conductive
500
This is the term used for a change in the AH interval by 50ms or greater when the coupling interval is decreased by 10ms during atrial extrastimulus pacing
What is an AH jump
500
Typical atrial flutter travels in a counterclockwise or clockwise direction, using this as the area of slow conduction
What is the cavotricuspid isthmus
500
This conduction tract conducts atrial impulses across the intraatrial septum to the left atrium
