Metal Distortion Meter – Displays the magnitude of the largest metal distortion deviation, indicating possible interference of the magnetic field due to the proximity of a metal object. 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. 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.

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 10x’s real-time speed. As an example, if the original mapping time were 10 minutes, the user can generate a second map in only 1 additional minute. This same concept could be employed for map3, map4, etc. 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.

Chapter 1. Introduction System Components
15
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 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.

Warnings and Cautions WARNING: A warning contains information for avoiding hazards that represent a significant hazard to the patient or operator. Warnings are also used for hazards that could significantly harm the EnSite™ Velocity™ Cardiac Mapping System. CAUTION: A caution contains information for avoiding hazards to the system components or improper system performance. Operator Requirements. The EnSite™ Velocity™ Cardiac Mapping System must be operated by, or under the supervision of, an
electrophysiologist trained in the operation of the EnSite™ Velocity™ Cardiac Mapping System and supported by other qualified personnel trained in the field of cardiac EP. It must be used in conjunction with other equipment required for electrophysiology studies such as suggested by the North American Society of Pacing and Electrophysiology1 (a.k.a. Heart Rhythm Society) and the American Heart Association2. Support Equipment. The EnSite™ Velocity™ Cardiac Mapping System is not intended for use as a primary ECG monitor. During
EnSite™ Velocity™ Cardiac Mapping System studies, an ECG monitor that conforms to safety requirements defined in IEC 60601, designated as the primary ECG monitor, must be present. Connections to non-EnSite™ Velocity™ Cardiac Mapping System equipment. Observe the following:
CAUTION: Sudden impedance changes of the body or catheter electrodes caused by the connection of other devices (e.g., stimulator, defibrillator, and other devices) may create a location shift. ■
Do not modify or make any additional connections to the EnSite™ Velocity™ Cardiac Mapping System, other than those described in this manual.
■
Do not connect the system to multiple portable socket outlets or extension cords.
Patient Safety. Observe the following:
WARNING: For patient safety, any connections that directly connect the patient to the EnSite™ Velocity™ Cardiac Mapping System must be routed through the appropriate module: NavLink, ArrayLink, CathLink, SJM ECG Cable, RecordConnect, or GenConnect. CAUTION: The EnSite™ Array™ Catheter is intended for single use only. Device integrity will be compromised by any reuse, which may compromise patient safety and system performance. CAUTION: The EnSite™ Velocity™ Surface Electrode Kit is intended for single use only. Device integrity will be compromised by any reuse, which may compromise patient safety and system performance. ■
Do not touch non-medical equipment and the patient at the same time.
Damaged Cables. Between studies, inspect cables for insulation or connector damage. Replace damaged cables immediately. Validating the EnSite™ Array™ Catheter. Always have the EnSite™ Array™ Catheter inserted into the patient before validating the
catheter in the software. Validating EnSite™ NavX™ Navigation and Visualization Technology. Before validating EnSite™ NavX™ Navigation and
Visualization Technology make sure that all connections have been made between the EnSite Amplifier and DWS. Ensure that the EnSite™ NavLink™ Module is connected to the EnSite™ Amplifier and that all EnSite™ Velocity™ surface electrodes have been connected as described. In particular, make sure that the left leg surface electrode is connected to the EnSite™ NavLink™ Module. External Stimulation. When using stimulus inputs on multiple EP systems, use care not to deliver stimulus through multiple paths. Software Warning Messages. Caution: Always respond to warning messages as soon as possible. Failure to do so may cause an inability to record data or to communicate properly with the EnSite™ Amplifier. 1.

Navigation. Adhere to the following to ensure accurate navigation:
CAUTION: Make all connections between systems before validating EnSite™ NavX™ Navigation and Visualization Technology. Adding or removing connections after validation may affect navigation quality. Additionally, all patient connections to ancillary equipment (e.g. external defibrillators) should be made prior to validation. Connections between systems refers only to SJM-supplied or approved devices. CAUTION: When the EnSite™ Amplifier is turned off, it can affect ECG signals viewed on the recording system. When the EnSite™ Amplifier is turned off and a recording system is in use, it is recommended that the cables to the EnSite™ Cardiac Mapping System be disconnected from the EnSite™ Amplifier. WARNING: Do not use Stabilize ABL in situations where the proximal electrodes on the ablation catheter may be covered by a sheath. CAUTION: (EnSite™ Array™ Catheter studies) If the EnSite™ Array™ Catheter is repositioned or unintentionally moved, a new model must be created. If a new EnSite™ Array™ Catheter is introduced, a new study must be started. ■
For EnSite™ NavX™ Navigation and Visualization Technology studies, a new study must be started if any of the EnSite™ Velocity™ surface electrodes are repositioned.
■
EnSite™ NavX™ Navigation and Visualization Technology studies intending to use Field Scaling must not have electrodes in a sheath during point collection.
NOTE: ■
Using location information from non-functional electrodes may yield unexpected Field Scaling results. This cannot be reversed. However, the use of Field scaling is optional and can be unapplied if unexpected results are seen.
Check for and disable non-functional electrodes or electrodes in a sheath before creating a model. Collecting points from nonfunctioning electrodes or electrodes in a sheath can result in unexpected field scaling results. See “Field Scaling” on page 121 for details.
Noncontact Mapping. Use appropriate techniques when interpreting data from noncontact maps:
CAUTION: When placing bipolar virtual electrodes near the poles of the map, select latitudinal orientations. Failure to do so may cause the electrograms to be computed improperly, resulting in inaccurate traces. CAUTION: If the high pass filter is set to low frequencies (< 2Hz), signals may be subject to low-frequency baseline drift. CAUTION: In the caliper measurements for noncontact isochronal maps and Substrate Mapping, do not use portions of the waveform display that have purple waveforms. CAUTION: If the EP catheter electrode is not in contact with the endocardium, the comparison between the EnGuide virtual electrogram and the EP catheter electrode may not accurately reflect the relationship between these signals. CAUTION: Do not disconnect the Array Module from the EnSite™ ArrayLink™ Module or the EnSite™ ArrayLink™ Module from the EnSite™ Amplifier during a study. Shutting Down the Workstation. To shut down the workstation, always follow the instructions in “Ending a Study” on page 195.
WARNING: If the workstation is powered off by the user, rather than shutdown by the operating system, data on the hard drive may become corrupted and the EnSite™ Velocity™ Cardiac Mapping System may cease to be operational. Removable CD/DVD Handling. CD/DVDs must be handled with care. Do not allow CD/DVDs to fall onto a hard surface. Do not place paper labels on the CD/DVD, write directly on the CD/DVD. Surface Electrodes. Use care in applying and removing surface electrodes (ECG, system reference, EnSite™ Velocity™ surface
electrodes): CAUTION: Ensure that surface electrodes and associated connectors do not contact one another, electrical ground, or metallic objects. CAUTION: Do not attempt to connect the system reference surface electrode for the EnSite™ Velocity™ Cardiac Mapping System to other equipment, such as ablation systems.
