Overview Of CARTO 3 Software Modules

Question 1

Modular Programming

Answer 1

A software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.

Question 2

Software Module

Answer 2

An independent part of a software program responsible for one aspect of function. Because modules act independently from the overall software program, they can be deleted or added at will to create a customized program.

Question 3

Scalable System

Answer 3

The ability of the CARTO® 3 System to accommodate procedural needs depending on the complexity of the case. A simple case does not require several modules, and therefore the CARTO® 3 System can be scaled down according to the physician’s preference. Or, if the procedure is complex, the CARTO® 3 System can be scaled up according to the physician’s needs.

Question 4

Filter

Answer 4

Electrogram processing that eliminates high or low frequency components within a set threshold.

Question 5

Location Tag

Answer 5

A tag type that can be used to catalog an EA point with a colored ball that contributes to the geometry of the map but not to the electroanatomical data.

Question 6

Grids

Answer 6

Show the total cumulative RF time in a particular anatomical location.

Question 7

Contact Force

Answer 7

The magnitude and direction of force applied to cardiac tissue during ablation.

Question 8

Force Vector Dashboard

Answer 8

Details the contact force by showing: the magnitude of force against the tissue, the % of time the catheter is in contact with tissue in the predefined range, and the angle of the catheter tip.

Question 9

Force Graph

Answer 9

Shows the range of force applied, in real-time, throughout the case, and can offer insight as to contact force stability.

Question 10

Ultrasound

Answer 10

An imaging modality that uses sound waves to visualize body tissue such as cardiac structures. The sound waves echo off the cardiac tissue, and different densities of tissue will reflect varying degrees of sound. These echoes are recorded and displayed on a monitor.

Question 11

ICE

Answer 11

IntraCardiac Imaging technology. An ultrasound taken from inside the heart using a catheter.

Question 12

Fluoroscopy or Fluoro

Answer 12

An imaging technique that uses x-rays to obtain real-time, moving images.

Question 13

EP Lab

Answer 13

Electrophysiology Lab. A lab that treats those with abnormal heart rhythms.

Question 14

Map Consistency

Answer 14

Identifies points with timing not consistent with the timing values of neighboring points.

Question 15

Wavefront Annotation

Answer 15

An algorithm that automatically annotates electrogram signals to determine their sequence and timing.

Question 16

TPI

Answer 16

Tissue Proximity Indicator. An algorithm that continuously measures and compares the catheter electrodes’ impedance and indicates when the catheter is within proximity to cardiac tissue.

Question 17

MEM

Answer 17

Multi-Electrode Mapping technology. MEM allows for acquiring several mapping points simultaneously.

Question 18

Continuous Mapping

Answer 18

An algorithm that uses a series of filters to select points that meet a pre-defined criteria to be applied to a map quickly and automatically.

Question 19

Discrete Signal

Answer 19

An electrogram signal that is a single, clear event with a sharp deflection.

Question 20

Fractionated Signal

Answer 20

A prolonged low amplitude signal. It is ‘complex’, meaning there are many positive and negative components.

Question 21

Idiopathic Ventricular Tachycardia

Answer 21

A heart arrhythmia characterized by Premature Ventricular Contractions (PVCs), or abnormal contractions that originate in the ventricles.

Question 22

Pace Mapping

Answer 22

A technique where the physician paces the cardiac tissue from the mapping catheter in order to attempt to reproduce the clinical PVC. The morphology of the body surface ECG of the paced beat is compared to the morphology of the clinical PVC in order to locate the source of the arrhythmia.
