Device Story

Zymed EasiView is a telemetry central station monitor for real-time cardiac monitoring of up to eight patients. System inputs include ECG signals from transmitters (VHF band 174-216 MHz) and cardiac pacemaker information. The system performs real-time ECG waveform analysis, including multi-channel automatic ST analysis, to detect and classify abnormal beats and rhythm disturbances. Operated by clinicians in a hospital setting, the system provides visual/audible alarms, derived 12-lead displays, trend data, and full disclosure review. These tools assist healthcare providers in diagnosing heart conditions and evaluating treatment efficacy, potentially improving patient management through continuous monitoring and automated detection of cardiac events.

Clinical Evidence

Bench testing only. Performance validated against AHA, MIT, and European ST-T (EST) databases. Metrics included sensitivity, positive predictivity, and false positive rates for QRS, ventricular, coupler, and run events. Performance demonstrated for high heart rates (>300 bpm) and in the presence of baseline, electrode, or muscle noise. Results showed performance nearly identical to the predicate system.

Technological Characteristics

IBM PC AT compatible platform; 200 MHz Pentium Pro CPU; 64 MB RAM; 16 GB hard disk; SVGA display. Operates on Windows NT/DOS. Supports 4, 6, or 8-bed monitoring. ECG transmitters operate in 174-216 MHz VHF band. Features multi-channel automatic ST analysis algorithm. Connectivity via network/chart recorder/laser printer.

Indications for Use

Indicated for pediatric to adult patients for assessment of heart rhythm disturbances, palpitations, arrhythmia risk, antiarrhythmic therapy efficacy, pacemaker function, real-time ST segment analysis, and ischemic heart disease evaluation during exercise testing in a single-hospital environment.

Regulatory Classification

Identification

The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document.

Zymed Telemetry System: Model EasiView - 510(k) K 951370

Zymed Holter Scanning System: Model 2010 - 510(k) K 930806

Description: A Zymed Telement monitoring system consists of a series of interface devices to include ECG transmitters, a central Telementy monitoring computerized until a surin chart recorder, Easi 5 (12 lead derived), and laser printer. The Zymed central monutor supports up to eight parients for real time curdial monitoring. The system displays each patient's ECG community on the screen while performing real time ECG wave form analysis for all eight patients. Thus analysis permits immediate detection and classification of abnormal beats, cardiac rhythm disturbances and variations.

Each ECG transmitter's frequency can be programmed to operate at any frequency within the entire VHF band For US domestic sites, the transmitters will comply with FCC band allocations (174-216 Mich. In addition to ECG data, the transmitters also detect and transmit cardiac pacemaker information. Other information including transminer status and individual lead impediated is the Zyned system for overall system safety and efficacy.

The Zymed system presents the user with a number of clinical tools such as visual and audible alarms and derived 12 lead display for the diagnosis of parients with various heart conditions. The system also provides tools to review a patient's cardiac performance. Con-line review mechanisms as well as detailed analysis screens have been designed into the system to facilitate and to enhance the patient's diagnosis and treatment. Features such as individual ECG printous, multi-channel automatic ST analysis, trend data analysis, and Full Disclosure data further enhance the system's qualities as a valuable and practical clinical ശി

The system has the following options available:

Choice of 4, 6, or 8 bed central monitor Full disclosure screen and printout (full resolution programmable from 0 to 168 hours) Choice of 6 lead sets, based on transminer capability Full arthythmus analysis to include multi-channel automanc ST Analysis 12 lead ECGD Laser Printer, print server options Suip Chart Networking

A review of the technological characteristics compared to the predicate devices are:

{2}------------------------------------------------

The only difference between the rwo Zymed systems is the addition of automanc Multi-channel ST Analysis/alarm to the algorithm.

Performance was measured against industry accepted AHA (AHA), MIT (MIT) and European ST-T (EST) databases. Results were typical for the real time monitoring environment for the EasilView as targeted. Separate sensitivities (SE), positive predictivity (+P), and false positive nate (FPR) were examined for each database and measured for QRS, Venricular, Couplers, Short nuns and Long nuns. High heart rates to include pediatic patients were demonstrated to be within recommended guidelines in excess of 300 bygm, and performance in the presence of noise indicates the new system is equal to or better than the old system when looking at baseline, electrode or muscle as the cause of noise.

In summary, performance data between the two systems shows nearly identical data, and therefore, supports a claim of Substantial Equivalence.
