Indications for Use
The EP-WorkMate® system with an EP-4 stimulator is intended to be used for diagnostic electrical stimulation of the heart for the purpose of refractory measurements, initiation and termination of tachy-arrhythmias, measurements of electrical conduction, and arrhythmia mapping.
Device Story
EP-WorkMate is a computer-based electrophysiological recording and monitoring system. Inputs include surface ECG signals and intracardiac electrical signals from indwelling catheters; optional intravascular pressure transducers. Signals are amplified, filtered, and digitized via a signal conditioning unit. Software performs online recognition of cardiac activation via automated waveform detector (trigger); computes temporal interval measurements on a beat-by-beat basis. System displays real-time and review data on dual high-resolution monitors. Used in clinical settings by physicians/technicians during electrophysiology studies. Output includes real-time waveform display, interval measurements, and stored study data. Integrated stimulator allows for diagnostic electrical stimulation of the heart. Data facilitates arrhythmia mapping, conduction measurement, and tachy-arrhythmia management. System supports connectivity to external devices like ablation generators and imaging systems.
Clinical Evidence
Bench testing only. No clinical data presented.
Technological Characteristics
Computer-based system; dual 21" monitors; multi-channel signal amplifier/filtering unit; catheter junction box; laser printer. Connectivity via Ethernet, RS-232, and USB.

## Device Description
The EP-WorkMate system is a computer-based electrophysiological recording and monitoring system that is used to capture, display, store, and retrieve surface and intracardiac electrical signals during electrophysiology studies. It consists of a computer. two 21" high-resolution monitors, a multi-channel signal amplifier and filtering system (signal conditioning unit), a catheter junction box, and a laser printer. The system may also be configured with an integrated EP-4 clinical stimulator and touch-screen computer monitor (cleared in K040207).
The EP-WorkMate is connected to electrophysiology catheters that are guided into various locations within the heart, and to surface electrocardiogram (ECG) cables. Intracardiac and ECG signals are then acquired from electrodes on the indwelling catheters and ECG leads, and transmitted to the amplifier, which amplifies and conditions the signals before they are received by the EP-WorkMate computer for measurement and display.
During the procedure, cardiac signals are acquired and an automated software waveform detector (trigger) performs online recognition of cardiac activation on preselected leads. Temporal interval measurements are computed on multiple channels on a beat-by-beat basis and dynamically displayed on the real-time display. Menu-driven
{1}------------------------------------------------
software is utilized for data acquisition and analysis, interval posting, and instant data retrieval with waveform markers and intervals displayed.
Signals are also presented on a review monitor for measurement and analysis. Continuous capture of the digitized signals can be invoked, and the user can also retrieve and display earlier passages of the current study without interruption of the realtime display. The system can also acquire, display and record data from other interfaced devices in use during the procedure, such as imaging devices and ablation generators,
### Software Description
The EP-WorkMate's system functions are controlled by the system software - signal acquisition, amplification, conditioning and display, electrocardiograph recording and monitoring, case annotation, and data output to external components, storage and retrieval. The menu-driven software is controlled through a user interface with a keyboard or mouse.
Key features of the EP-WorkMate are:
- Dual monitors real-time and review .
- Signal analysis tools ●
- Real-time interval analysis ●
- Integrated stimulator ●
- Activation mapping
- . Pace mapping tools
- Fully integrated RF and cryo ablation generator interfaces .
- Ablation window
- Holter window .

- Full report and printout functions ●
#### Hardware Description
The EP-WorkMate consists of a computer, two 21" high-resolution monitors, a multichannel signal amplifier and filtering system (signal conditioning unit), a catheter junction box, and a laser printer. The system may also be configured with an EP-4 clinical stimulator and touchscreen computer monitor (K040207).
### Connections
The patient is connected to the EP-WorkMate by a surface ECG cable, intracardiac catheters and optional intravascular pressure transducers. Patient ECG and catheter
{2}------------------------------------------------
cables are connected directly to the electrically isolated junction box, and pressure transducers are connected to the amplifier and signal conditioning unit (SCU) box.
The signal amplifier and signal conditioning unit (SCU) box receives signal inputs from the iunction box and marker/pressure interface box. The signals are then amplified, converted from analog to digital, filtered/conditioned and transmitted to the EP-WorkMate computer via Ethemet cabling.
The computer receives inputs from the amplifier/SCU as well as additional data received via standard RS-232 and USB connections from the cardiac stimulator and other external device sources. The computer then transmits data to the EP-WorkMate's realtime and review monitors for display, as directed by user inputs entered through a mouse and/or keyboard computer interface. Digitized case data are also transmitted to the system printer, DVD-R drive, or networked connection. See Figure 1 for a graphical presentation of system interconnections.
Image /page/2/Figure/6 description: This image shows a diagram of a medical monitoring system. The system includes sensors attached to a human body that measure pressure, catheters, and a 12-lead ECG. These sensors are connected to a junction box and amplifier, which then sends data to a CPU. The CPU processes the data and displays it on a real-time monitor and a review monitor, and it can also print the data using a printer.

## 510(k) Summary
### Device Comparison to the Cleared Device
The EP-WorkMate has the same intended use and fundamental scientific technology as the predicate device. All technological characteristics of the EP-WorkMate system are substantially equivalent to the predicate device.
## Summary of Non-Clinical Testing
Bench testing was performed to confirm that the changes met design requirements and did not affect the safety or effectiveness of the product.
#### Summary of Design Control Activities
The development of the EP-WorkMate system was performed in accordance with St. Jude Medical's Quality System requirements, and in compliance with Quality System Regulation design controls requirements documented in 21 CFR 820.30. A Declaration of Conformity with Design Controls is provided in Attachment I.
#### Conclusion
The EP-WorkMate has the same indications for use, intended use and fundamental scientific technology as the predicate devices. All technological characteristics of the EP-WorkMate are substantially equivalent to the predicate device.
Where operational and performance differences exist between the proposed device and the predicate device, performance testing demonstrated that these differences do not adversely affect the device's safety and effectiveness.
Therefore. St. Jude Medical considers the EP-WorkMate to be substantially equivalent to the predicate devices.
