Electrophysiology

Anatomy

100

This cardiac structure initites atrial depolarization and acts as the natural pacemaker

What is the SA node

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

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?

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

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?

SVT

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?

200

This reentrant tachycardia uses an accessory pathway and the AV node to sustain a fast arrythmia.

What is AVRT?

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?

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?

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?

EP study

100

What is the name of  the catheter placed in the ventricle during an EP study?

What is RVA?

200

How long is a normal P-R interval

What is ~ 160ms?

300

What is the Wenckebach point?

What is pacing interval at which the loss of 1:1 V-A conduction occurs?

400

What is a normal H-V interval?

What is 35-45ms?

500

Why do we do incremental AV pacing last?

what is It can induce A fib?

Ablations

100

this is the best Ablation catheter on the market for AFib

What is FARAWAVE?

200

This type of ablation catheter is non-irrigated and is used to ablate thicker, more fibrous tissue and typically produces deeper lesions.

What is an 8mm catheter?

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?

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?

500

This type of ablation uses freezing to destroy cardiac tissue and is commonly used in younger patients undergoing AVNRT ablation.

What is cryoablation?

Mystery

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 medication is given IV, is used to block the AV node and has a six second half life.

What is adenosine?

300

This phenomenon is used to describe the inability of electrically paced stimuli to exit the pulmonary veins.

What is exit block?

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 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?
