The EnSite™ Velocity™ Cardiac Mapping System with software version 5.2 / EnSite Precision™ Cardiac Mapping System with software version 2.2 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 three-dimensional maps are based on the anatomy of the patient's own cardiac chamber.
The EnSite™ Velocity™ Cardiac Mapping System is used as a diagnostic tool in electrophysiology (EP) Studies. An EP study involves the introduction of one or more electrode catheters into the heart to record its electrical activity. These catheters connect to the EnSite™ Velocity™ Cardiac Mapping System through specialized catheter input modules (CIMs). The EnSite™ Velocity™ Cardiac Mapping System v5.2 is designed for use in the EP laboratory in conjunction with other equipment.
The EnSite Velocity™ Cardiac Mapping System consists of hardware and software elements. The EnSite Velocity / EnSite Precision System consists of software, a display workstation (DWS) subsystem (DWS, Monitors, DWS Accessory Kit, and DWS Power Kit), and an amplifier subsystem (Amplifier and Amplifier Accessory Kit). The DWS houses the system software and connects all the components together. The amplifier contains electronic circuitry and firmware responsible for collecting and transmitting the electrical signal data of the patient to the DWS software. Its primary function is to collect and transmit via Ethernet the electrical data detected from the patient. The amplifier accepts signals from NavLink, ArrayLink, CathLink, ECG Cable, RecordConnect, and GenConnect, converts these signals to a digital format, and sends them to the workstation for processing.
The NavLink connects surface electrodes and the system reference surface electrode to the Amplifier. The ArrayLink connects the EnSite Array Multielectrode Diagnostic Catheter to the Amplifier. It also has a connection for an auxiliary unipolar reference electrode. The CathLink connects the diagnostic catheters to the Amplifier. The GenConnect connects the ablation catheter and dispersive surface electrodes to the Amplifier. The RecordConnect allows simultaneous connection for catheters and surface ECG to a recording system and to the Amplifier. The ECG cable connects standard ECG electrodes to the Amplifier.
The system operates using impedance only or impedance plus magnetics based upon its configuration. The EnSite™ Velocity™ Cardiac Mapping System base software only collects impedance data. Adding EnSite Precision™ software to the base software allows the system to receive both magnetic data from the MediGuide™ Technology System or the EnSite Precision™ Module hardware and impedance data when using magnetic sensor enabled tools. The EnSite Precision™ Module and EnSite Precision™ software (added to the base software) together make up the EnSite Precision™ Cardiac Mapping System.
The EnSite Precision™ software interfaces to the MediGuide Technology System or the EnSite Precision™ M Module to collect magnetic position and orientation information. The EnSite Precision™ software uses the magnetic data for magnetic field scaling (NavX SE), shift detection (EnGuide Stability Monitor), and respiration gating. NavX SE field scaling adjusts the dimensions of the navigation field based on both the positon and orientation of magnetic sensors and the electrodes on Sensor Enabled™ (SE) tools, optimizing the appearance of the model. The system uses EnGuide Stability Monitor to notify the user of a potential shift based on a correlation of magnetic and impedance locations when using any Sensor Enabled catheter. The system uses respiration gating to compensate to the end-point of the respiration cycle using magnetic data to determine respiration phase.
The EnSite Precision™ Module consists of hardware to support magnetic navigation. The hardware components consist of the EnSite Precision™ Link, EnSite Precision™ Field Frame, and EnSite Precision™ Patient Reference Sensors.

The provided document does not contain information about a study that proves a device meets acceptance criteria for an AI/ML-based medical device. Instead, it is a 510(k) clearance letter for the EnSite™ Velocity™ Cardiac Mapping System v5.2 and EnSite Precision™ Cardiac Mapping System v2.2, which are described as programmable diagnostic computer systems. These systems are used for catheter navigation and mapping in electrophysiology studies.
The document discusses validation activities for functional testing related to hardware and software modifications, as well as verification testing against industry standards. However, it does not detail a clinical study with acceptance criteria and performance metrics typically associated with proving the effectiveness of an AI/ML diagnostic tool, such as sensitivity, specificity, accuracy, or human-AI comparative performance.
Therefore, I cannot extract the requested information to fill in the table and describe the study as it pertains to AI/ML device performance. The testing described largely relates to electrical safety, electromagnetic compatibility, basic system function, system-level accuracy, and software/hardware verification after proposed modifications.
To answer your request, if this were an AI/ML device, the study would typically involve:
