EP Phone Home
The diagnostic process by which an EP establishes baseline conduction properties of a patient’s heart by pacing and taking precise measurements.
What is an EP Study?
Most common form of SVT in adults.
What is AVNRT?
SVT rhythm that has a saw tooth P wave pattern on a 12-Lead ECG.
What is Atrial Flutter?
Catheter that can obtain contours of left side heart anatomy from the right side of the heart.
What is Soundstar?
An irregular, life-threatening ventricular rhythm
Ventricular fibrillation (VFib)
Nerve that can be stimulated by high-output pacing in the superolateral RA or occasionally in the anterior RSPV.
What is the Phrenic Nerve?
The main source of AFib triggers.
What are Pulmonary veins?
Atrial flutter that is NOT dependent upon the cavo-tricuspid isthmus (CTI).
What is Atypical Flutter?
Biosense Webster mapping catheter that has 8 splines and 48 electrodes.
What is an Octaray?
A common interval measured to distinguish AVNRT from AVRT.
What is VA time?
The primary, secondary and tertiary pacemakers of the heart.
What are the SA node, AVN, and Purkinje fibers?
The pacing manuever used to identify a VAAV response.
What is entrainment?
Arrythmia associated with a Delta Wave on the 12 lead EKG.
What is WPW?
Ablation marker that catalogs lesions based on power, contact force and time in a formula.
What is ablation tag index? (f prime or SURPOINT)
Measurement from the last entrained stim signal to earliest recurring signal on that bipole.
What is PPI?
Main parasympathetic nerve that innervates the heart.
What is the Vagus Nerve? (vaso-vagal response)
A CS activation pattern what might indicate a left-sided pathway.
What is Eccentric activation? (distal to prox)
An atrial beat, not originating from the SA or AV node, that can initiate tachycardia.
Premature Atrial Contraction (PAC)
Catheter that displays local conduction vectors
Who is the Optrell catheter?
During extrastimuli pacing with decremental S2, this change in AH timing indicates an AH jump.
What is 50 ms or greater?
When delivered to tissue, this energy causes targeted irreversible electroporation of cells.
What is PFA?
A type of pathway with only retrograde conduction.
What is a Concealed pathway?
A rhythm indicated by irregular R-R intervals and F waves.
What is Atrial Fibrillation?
Catheter that contains 3 microelectrodes for high resolution signals and 6 thermocouples to closely monitor tissue/catheter tip interface.
What is the QDOT catheter?
Average facility cost of each minute of an AFib ablation procedure.
What is $29/min
