Indications for Use
EMS-XL is indicated to acquire, filter, digitize, amplify, display and record electrical signals obtained during electrophysiological studies and related procedures conducted in an electrophysiological laboratory. Signal types acquired include ECG signals, direct cardiac signals and pressure recordings. Physiological parameters such as the diastolic, systolic and mean blood pressure, heart rate and cycle length are derived from the signal data, displayed and recorded. The system allows the user to monitor, display and record the signal data. The system allows the user to monitor the acquisition data, review the data, store the data, perform elementary caliper-type measurements of the data, and generate reports on the data. The system may display and record data received from other medical devices typically used during these procedures, such as Ablation RF generators. The system incorporates a stimulator intended to be used for diagnostic cardiac stimulation during electrophysiological testing of the human heart.
Device Story
The EMS-XL is a software-driven cardiac electrophysiology system used in clinical labs by physicians. It acquires, digitizes, and amplifies 12-lead surface ECG, blood pressure, and 18-50 channel intracardiac ECG signals via a patient connection box. An integrated, computer-controlled stimulator provides diagnostic pacing protocols (e.g., SNRT, overdrive, Wenckebach). The system features two displays: one for real-time waveform monitoring and one for non-real-time review, analysis, and report generation. It interfaces with ablation RF generators to display procedure parameters. Data is stored for archival and review. The system assists clinicians in diagnosing tachy-arrhythmias and conduction pathway issues by providing tools like on-screen calipers, event marking, and template comparison. It benefits patients by enabling precise electrophysiological mapping and diagnostic stimulation during cardiac procedures.
Clinical Evidence
Bench testing only. No clinical data provided. Substantial equivalence is based on technical specification comparisons, compliance with electrical safety standards (IEC 60601-1, EMC), and performance characteristics relative to predicate devices.

#### Device description
The EMS-XL Cardiac Electrophysiology System consists of a software driven, multichannel amplifier and stimulator that are connected to a computer.
Input signals include 12 lead surfaces ECG, two Blood pressure channels and 18 or 50 channel intra-cardiac ECG.
The signals are digitized and sent to the computer for analysis, display and storage.
Signals are displayed with sweep speeds of 25 to 300mm/sec in either predefined or customized configurations.
The system consists of a computer, Front end amplifiers with integrated stimulator.
Two display screens, one used for Real Time signal display and the other for Non real Time display for analysis and review and playback of stored signals.
A Laser printer is used to print surface and intra-cardiac ECG and a CD or DVD is used for archive of signals.
The two display screens are used to show the signals. The real time display, RT, shows the real time signal waveforms. Each waveform channel is color-coded for easy identification. The non real time display, NRT, serves as a Review monitor allowing the manipulation and processing of data, including caliper measurements, event marking, snapshot storage and final report processing.
The stimulator is computer controlled and provides basic stimulation rate plus up to 4 stimulations delayed after the basic stimuli. Stimulation can be either synchronized to the cardiac electrical activity or non synchronized. Pacing protocols with automatic increment and decrement functions provides refractory period measurements.
A variety of stimulation sequences can be created and stored for future use.
The EMS-XL can be used for all types of electrophysiological procedures, including His bundle recording, Sinus Node Recovery Time - SNRT, Overdrive, Wenckebach, and tachy-arrhythmias. An interface to ablation generators provide Ablation Start and End information with data on the ablation parameters.
Each waveform is color-coded for easy identification.
The review monitor allows the manipulation and processing of data, including caliper measurements, event marking, snapshot storage and final report processing.
Special display options support the signal analysis
This includes Trigger mode and template comparison. Event marking. Holter mode: quick. minute-by-minute scrolls and jumps to event, On screen calipers: both real-time and review screen with auto measurement , Auto Tachycardia detection. Free text labeling, and Customized reports in Word™.
The input to the amplifiers is via a patient connection box, to which the intra-cardiac catheter electrodes (not manufactured and not supplied by Mennen Medical) are connected.
