CHAPTER 1
Indications for Use The EnSite™ Velocity™ Cardiac Mapping System is a suggested diagnostic tool in patients for whom electrophysiology studies have been indicated. ■
When used with the EnSite™ Array™ Catheter, the EnSite™ Velocity™ Cardiac Mapping System is intended for use in electrophysiology studies to aid the electrophysiologist in diagnosing cardiac arrhythmia. OR
■
When used with an EnSite™ Velocity™ Surface Electrode Kit, the EnSite™ Velocity™ Cardiac Mapping System is intended to display the position of conventional electrophysiology (EP) catheters in the heart.
System Description The EnSite™ Velocity™ Cardiac Mapping System (Figure 1 on page 13) is a catheter navigation and mapping system capable of displaying the three-dimensional (3D) position of conventional electrophysiology catheters, as well as displaying cardiac electrical activity as waveform traces and as dynamic 3-D isopotential maps of the cardiac chamber. The contoured surfaces of these threedimensional maps are based on the anatomy of the patient’s own cardiac chamber.

Chapter 1. Introduction Key System Features
EnSite™ Velocity™ Cardiac Mapping System Instructions for Use ARTEN600035011 A
Key System Features Catheter Catalog – Catheter-specific information, including catheter diameter, tip electrode size, body electrode size, type, and interelectrode spacing, can be saved to a searchable catalog. Clipping Plane . The clipping plane helps to increase the understanding and relationship of the model to other related features while reducing visualization obstructions. Contact Mapping. Maps can be created from conventional EP catheters. Maps can display various information, including: activation
timing, peak-to-peak voltage, peak-negative voltage, or complex fractionated electrograms. ■
■
MultiPoint Mapping Technology – Map points can be added from the active electrode, all electrodes on a specified catheter, or all electrodes in use. Low -V ID – An adjustable Low Voltage Identification (Low -V ID) option allows low-voltage potentials to appear in gray instead of affecting the color pattern. Low - V ID is available for Local Activation Time (LAT) isochronal maps and Complex Fractionated Electrogram (CFE) maps.
Data Storage and Export Capabilities. During an EP study, the monitors display the data and that data can be stored on the DWS
hard drive. Once the study is complete, a prompt is displayed to remind the user to back up the study data. ■
■
■
■
Patient records are stored in a database searchable by patient name, patient weight, physician name, date, diagnosis, and study type. Records are copied to CD/DVD, USB, and network drive. Still images, animations, and study data can be exported to a CD/DVD, USB, and network drive, which can then be displayed and reviewed using a non-EnSite™ Velocity™ Cardiac Mapping System computer. The study images can be printed using a color printer.
Delayed Enhancement Magnetic Resonance Imaging. – (DEMRI) See “DEMRI (Delayed Enhancement MRI) Image Integration”
on page 135. DIF Map – Digital Image Fusion Map. Digital Image Fusion (DIF). Digital images processed by segmentation tools such as the EnSite™ Verismo™ Segmentation Tool can
be imported into the EnSite™ Velocity™ Cardiac Mapping System for display. Field Scaling. – Field Scaling can be configured to automatically scale model, map, and EnGuide catheter locations and facilitates distance measurements. ■
EnSite™ NavX™ Navigation and Visualization Technology (NavX): Known interelectrode spacing used to create the model is used to adjust the dimensions of the navigation field.
First Deflection – Searches for the first spot in the signal (from left to right) where the signal deviates from isoelectric baseline by at least the sensitivity amount. Fractionation Map – Displays the area of the map where there are clusters of Fractionation and is useful in identifying noisy points or points that require more attention.Indicates the number of CFE detections. Image and Animation Export (Offline Review only) – Several options allow images and animations to be captured from the system: ■
Image sequences can be exported as either a series of JPEGs or as an mpeg (.mpg) movie.
Last Deflection – Searches for the last spot in the signal (the first spot when scanning from right to left to right) where the signal
deviates from isoelectric baseline by at least the sensitivity amount. Models of Cardiac Chambers. The EnSite™ Velocity™ Cardiac Mapping System can generate a model of one or more of the patient’s cardiac chambers by tracking conventional EP catheter electrodes at various locations on the surface of the endocardium.
EnSite™ Velocity™ Cardiac Mapping System Instructions for Use ARTEN600035011 A
Chapter 1. Introduction Key System Features
15
Noncontact Mapping. (EnSite™ Array™ Catheter studies only) When the EnSite™ Velocity™ Cardiac Mapping System is used along with the EnSite™ Array™ Multi-Electrode Catheter, the system can collect, store, and display more than 3000 intracardiac electrograms. Several tools are available to facilitate interpretation: ■
■
AutoFocus Color Controls allow the system to automatically adjust the color levels of isopotential maps to quickly and clearly identify activation patterns. Isopotential Mapping displays voltages sensed by the EnSite™ Array™ Catheter as three-dimensional maps, which use color to represent a range of electrical potentials across the surface of the heart chamber’s endocardium. These maps contain the electrical potentials at thousands of sites on the endocardial surface. As dynamic cardiac signals are viewed in the waveform display, the same information is animated in the display of the isopotential map.
■
Single-Beat Isochronal Maps of activation time can be projected onto the surface of the anatomic model in review mode.
■
Substrate Mapping (SM) Tool allows voltage patterns from noncontact mapping to be displayed as maps and labeled on the map.
■
Virtual Waveforms are based on simulated electrodes placed on the map display.
Non-fluoroscopic Catheter Navigation. The EnGuide navigation system allows 3D navigation of conventional EP catheters. Notebook. The notebook allows recorded data and study information to be filed and annotated for future access. ■
Bookmarks can be added to the Notebook to allow the system to return to a specific time in review mode.
■
Events can be added to the Notebook to mark specific times in a study, such as the time of a drug administration.
OneMap. This feature is used to simultaneously create a cardiac chamber model and a contact map. Point Count Map – Provides a method to visualize areas of high map point density versus low map point density. Presets. Presets store setting preferences for catheters, models, maps, and layouts. Propagation Maps. This feature facilitates the playing back of the activation sequence of recorded reentrant maps. ■
Provides controls to turn this feature on/off and features to control the playing through the activation sequence.
■
Loops over the cycle length.
■
Export of propagation sequences are available only in Offline Review.
Reentrant Maps. These maps facilitate the mapping of reentrant arrhythmias and are displayed in a manner similar to activation maps. Respiration Compensation. (EnSite™ NavX™ Navigation and Visualization Technology studies only.) Respiration Compensation
can be configured to dynamically adjust to the motion artifact from patient respiration during an EnSite™ NavX™ Navigation and Visualization Technology study. Respiration Compensation can also be manually recomputed during a study. ■
■
Respiration Meter – A respiration meter displays the relative level of patient respiration in the map display, based on EnSite™ NavX™ Navigation and Visualization Technology transthoracic impedance. The range is based on the lowest and highest impedance values sampled during Respiration Compensation collection. Respiration Rejection – If a patient’s respiration exceeds the set limits of the respiration levels collected during Data Collection, the system will stop collecting points and stop placing labels and lesions at the Active EnGuide.
RF Filtering. Hardware filters provide cleaner signals during RF ablation. Saturation Recovery. Saturation Recovery allows the system to quickly recover signals following defibrillation or RF energy
ablation. Rapid system recovery allows assessment of post-defibrillation or post-ablation complexes. Screen Views. The interface can be configured to display different types of information. Various options are available to display
waveforms, one or two maps, and split screen. Sheath Filter – Determines if an electrode is within the sheath (Sheathed) or outside the sheath (Unsheathed).

Sparkle Map – Live activation map overlaid on the voltage map for easy visualization of voltage pathways on a single map. Stabilize ABL – The Stabilize ABL feature adjusts the location of the distal electrode, based on the properties of the catheter. Tape Measures. Tape measures allow measurement between points on the anatomic model of the endocardial surface.Tools to Provide Map Orientation. Several tools are available to enhance map orientation. TurboMap – Once original mapping has occurred, the user may change mapping criteria and play back through the original dataset at maximum speed to generate a new map at the DWS’s maximum speed. This may be useful if the physician is mapping Sinus Rhythm and intermittent, multiple PVC or VT morphology beats are occurring. This may also be useful if the physician is trying to map multiple, distinct Cycle Length atrial tachycardias. Waveform Traces. The EnSite™ Velocity™ Cardiac Mapping System has capabilities similar to traditional EP recording systems, including the ability to collect, store, and display surface ECG and intracardiac electrograms as waveform traces.

System Components The EnSite™ Velocity™ Cardiac Mapping System is comprised of two subsystems: the EnSite™ Amplifier and the Display Workstation (DWS).
EnSite™ Amplifier The EnSite™ Amplifier subsystem consists of the EnSite™ Amplifier, NavLink™ Module, ArrayLink™ Module, CathLink™ Module, SJM™ ECG Cable, RecordConnect, and GenConnect. The devices accept signals from electrodes attached to the patient and pass these signals to the EnSite™ Amplifier. The EnSite™ Amplifier converts these signals to a digital format and sends them to the DWS for processing. EnSite™ Amplifier. Accepts signals from the NavLink™ Module, the ArrayLink™ Module, the CathLink™ Module, SJM™ ECG Cable, RecordConnect, and GenConnect, converts these signals to a digital format, and sends them to the DWS for processing. The Amplifier is connected to the DWS through a fiber-optic cable. NavLink™ Module. Connects the EnSite™ surface electrodes and the system reference surface electrode to the EnSite™ Amplifier.
It also has a connection for an auxiliary unipolar reference electrode. ArrayLink™ Module. Connects the EnSite™ Array™ catheter to the EnSite™ Amplifier. CathLink™ Module. Connects diagnostic catheters to the EnSite™ Amplifier. SJM™ ECG cable. Connects standard ECG electrodes to the EnSite™ Amplifier. RecordConnect. Connects a recording system to the EnSite™ Amplifier without the need for jumpers. A different RecordConnect
model is required for each make of recording system. GenConnect. Connects the ablation catheter and dispersive surface electrodes to the EnSite™ Amplifier. It isolates the EnSite™ Velocity™ Cardiac Mapping System location signal from being loaded by the ablation generator, thereby eliminating the need for separate dispersive electrode filters. A different GenConnect model is required for each make of ablation generator.
NOTE:
GenConnect is not necessary when using the Ampere™ Generator.
Display Workstation (DWS) The DWS consists of the workstation (computer), monitors, medical grade isolation transformer, video extender, media converter, and Ethernet switch. Workstation. The workstation contains the system software displaying data from the EnSite™ Amplifier. Attached to the workstation are a keyboard and mouse for user input. Monitors. Monitors are used to display patient information. One monitor is placed near the workstation and keyboard for system operation, and an optional second monitor can be placed near the patient table for use by the physician. The monitors display identical information from the same source. Medical Grade Isolation Transformer. All system components on the DWS cart are connected to line power through the isolation
transformer. Only components of the DWS should be connected to this isolation transformer. Video Extender. This device splits the video signal so that the same information appears on both of the EnSite™ Velocity™ Cardiac Mapping System monitors. Media Converter. The Media Converter converts optical signals to digital signals. It connects to the hardware via a Fiber Optic Cable and connects to the DWS via an Ethernet cable and a USB cable, which is used for power only.

Ethernet Switch. The Ethernet Switch allows users to use multiple modules that require Ethernet connections in conjunction with the EnSite™ Velocity™ Cardiac Mapping System.
Components Not Included The following components are required for EP studies but are not included with the EnSite™ Velocity™ Cardiac Mapping System. EnSite™ Array™ Catheter. This noncontact multi-electrode catheter collects cardiac electrical information. Conventional EP Catheters . These catheters are introduced into the cardiac chamber of interest and placed in contact with the
chamber wall. Surface Electrodes – Six surface electrodes are used for the EnSite™ Cardiac Mapping System. ECG Electrodes. These industry-standard surface electrodes are placed in a standard 12-lead configuration. System Reference Surface Electrode. A system reference surface electrode is required for all EnSite™ ArrayLink™ Module and EnSite™ NavX™ Navigation and Visualization Technology studies. This surface electrode should be suitable for defibrillation or electrosurgery, such as the Covidien™ Valleylab™ Non-REM Polyhesive™ Patient Return Electrodes (see below).
Figure 2. Covidien™ Valleylab™ Non-REM Polyhesive™ Patient Return Electrode A system reference surface electrode is included in the EnSite™ Velocity™ Surface Electrode Kit. Printer. An optional printer is available for printing images and waveforms. Remote Monitor. The Remote Monitor can be purchased separately. This monitor is typically used in the Patient area of the lab, where the DWS may only be available in the control room.
