Mystery
100
This cardiac structure initites atrial depolarization and acts as the natural pacemaker
What is the SA node
100
This arrythmia usually affects young women and uses two separate pathways in the bundle of HIS to sustain a fast tachycardia.
What is AVNRT?
100
This type of arrythmia is charachterized by an appearance of twisting, polymorphic VT. It can quickly degenerate into V Fib.
What is Torsades de Pointes?
100
This type of ablation catheter uses a fluid cooled tip.
What is an irrigated catheter?
100
This medication is frequently given in the EP lab and is used to convert patients into normal sinus rhythm from Atrial Fibrillation.
What is corvert (ibutilide)?
200
This cardiac structure receives the electrical impulse from the atria then sends the signal to the ventricles via the HIS-Purkinje system
What is the AV node
200
This reentrant tachycardia uses an accessory pathway and the AV node to sustain a fast arrythmia.
What is AVRT?
200
Occasionally during a VT ablation, in an effort to avoid ablating this structure, the EP physician will perform a coronary catheterization to identify and locate this.
What are the coronary arteries?
200

This type of ablation catheter is non-irrigated and sometimes used for AVNRT or AV Node ablations

What is a 4mm or 8mm catheter?

200
This medication is given IV, is used to block the AV node and has a six second half life.
What is adenosine?
300
This structure is located in the left atrium and is known for harboring clots in A Fib patients due to blood stasis.
What is the Left Atrial Appendage?
300
This reciprocating tachycardia passes through the fibrous tissue located between the tricuspid valve and the IVC, an area known as the isthmus.
What is atrial flutter?
300
These structures are prevalent in the left ventricle and can impede movement of catheters, sometimes even tangling catheters to the point of requiring surgical removal.
What are the trebeculae?
300

This type of mapping involves the use of patches or magnets that give impedance feedback and assist the operator in locating the catheter in real-time space to help with identifying cardiac anatomy and ablation lesion sets.

What is 3D mapping, ESI or Carto?

300
This phenomenon is used to describe the inability of electrically paced stimuli to exit the pulmonary veins.
What is exit block?
400

This electrically inert area of the heart separates the atria from the ventricles and normally does not allow electricity to pass through

What is the AV groove

400
This Supraventricular tachycardia originates in the atria, may be either focal or mutifocal, and may present with varying P wave morphology or varying PR intervals.
What is atrial tachycardia?
400
This type of map, used to determine the viability of LV tissue, will help the physician assess which tissue is scar, and which is healthy.
What is a voltage map or a scar map?
400
This type of ablation approach uses an femoral arterial puncture site and is used when transeptal approach is not feasible or impractical.
What is a retrograde arterial approach?
400
This phenomenon describes the movement of electrical activity from a fast pathway to the slow pathway in the HIS. And is demonstrated by an increase of 50 or more msec of the AH interval on the HIS catheter from the last two paced atrial beats.
What is a jump?
500
This cardiac structure is an area of smooth muscle that is located in the left atrium between the left superior pulmonary vein and the left atrial appendage
What is the coumadin ridge?
500
When ablating A Fib, passing over these areas while ablating in the left atrium may produce a vagal response, requiring immediate pacing.
What are the ganglionic plexii?
500
When viewed on intracardiac signals, this electrical activity represents a slow moving electrical channel through scar during a VT ablation.
What are mid-diastolic potentials?
500
This type of ablation uses freezing to destroy cardiac tissue and is commonly used in younger patients undergoing AVNRT ablation.
What is cryoablation?
500
This complication can occur when a rise in esophageal temperatures manifests during ablation without corrective action. It can lead to sepsis and has a very high mortality rate.
What is atrioesophageal fistula?
