Device Story

Zymed Telemetry System (EasiView) provides real-time cardiac monitoring for up to eight patients in a single-hospital environment. System inputs include ECG signals from patient-worn transmitters (VHF band 174-216 MHz) and cardiac pacemaker information. The central monitoring unit performs real-time ECG waveform analysis, including arrhythmia detection, classification, and multi-channel automatic ST analysis. Output is displayed on an SVGA monitor, with options for strip chart recording, laser printing, and full disclosure data review. Clinicians use these tools to assess rhythm disturbances, evaluate antiarrhythmic therapy efficacy, and monitor ST segments. The system aids clinical decision-making by providing visual/audible alarms and detailed cardiac performance data, potentially improving patient diagnosis and treatment outcomes.

Clinical Evidence

Bench testing only. Performance validated against industry-standard AHA, MIT, and European ST-T (EST) databases. Metrics included sensitivity (SE), positive predictivity (+P), and false positive rate (FPR) for QRS, Ventricular, Couplets, and Short/Long runs. ST analysis performance measured via Episode Sensitivities (ESE), Episode Positive Predictivity (E+P), Duration Sensitivity (DSE), and Duration Positive Predictivity (D+P). System demonstrated performance in high heart rates (>300 bpm) and noise conditions (baseline, electrode, muscle) equal to or better than the predicate.

Technological Characteristics

IBM PC AT compatible platform; 200 MHz Pentium Pro CPU; 64 MB RAM; 1.6 GB hard disk; SVGA display. Transmitters operate on tunable VHF frequencies (174-216 MHz). Supports 4, 6, or 8-bed monitoring. Connectivity includes strip chart, laser printer, and networking. Software runs on Windows NT/DOS compatible OS. Features EASI derived 12-lead ST analysis.

Indications for Use

Indicated for pediatric to adult patients requiring cardiac rhythm monitoring, arrhythmia evaluation, pacemaker function assessment, ST segment analysis, and ischemic heart disease evaluation. EASI derived 12-lead ST measurements indicated for patients aged 33-82, height 147-185 cm, weight 53-118 kg, and specific height-to-weight ratios.

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.

Trade Name: Common Name: Classification Name: (per 21 CFR 870.1025) Zymed Telemetry System: Model EasiView Telemetry Central Station Monitor Detection and Alarm, Arrhythmia

Legally marketed device to which S.E. is claimed. Zymed Telemetry System: Model EasiView - 510(k) K 980186

Description: A Zymed Telemetry monitoring system consists of a series of interface devices to include ECG transmitters, a central Telemetry monitoring computerized unit with a strip chart recorder, Easi 5 (12 lead derived), and laser printer. The Zymed central monitor supports up to eight patients for real time cardiac monitoring. The system displays each patient's ECG continuously on the screen while performing real time ECG waveform analysis for all eight patients. This 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 Mbz). In addition to ECG data, the transmitters also detect and transmit cardiac pacemaker information. Other information including transmitter status and individual lead impedance is also transmitted to the Zymed 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 patients with various heart conditions. The system also provides tools to review a patient's cardiac performance. On-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 printouts, multi-channel automatic ST analysis, trend data analysis, and Full Disclosure data further enhance the system's qualities as a valuable and practical clinical tool.

The system has the following options available:

{1}------------------------------------------------

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 transmitter capability Full arrhythmia analysis to include multi-channel automatic ST Analysis 12 lead ECGD Laser Printer, print server options Strip Chart Networking

Intended use:

- Assessment of symptoms that may be related to rhythm disturbances of the heart: Patients with . palpitations; The evaluation of arrhythmia's in patients from pediatric to adult age.
- Assessment of risk in patients with or without symptoms of arrhythmia.
- Assessment of efficacy of Antiarrhythmic therapy. .
- . Assessment of Pacemaker Function.
- Assessment of real time ST segment analysis .
- . Assessment of symptomatic or asymptomatic patients, to evaluate for, ischemic heart disease and arrhythmia analysis during exercise testing.
- Assessment is for single-hospital environment.
- Assessment of EASI derived 12-lead ST measurements is recommended for patients that meet the . following parameters.
- 1. Ages: 33 to 82 years
- 2. Heights: 147 to 185 cm (58 to 73 in)
- 3. Weights: 53 to 118 kg (117 to 2611b)
- 4. Height to Weight Ratios: 1.41 to 2.99 cm/kg (0.25 to 0.54 in/b.)

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

| Platform | Easi View (New)<br>telemetry system | EasiView (Old)<br>telemetry system |
|---------------------|-------------------------------------|------------------------------------|
| Type | IBM PC AT Compatible | Same |
| CPU | 200 Mhz Pentium Pro | Same |
| RAM | 64 M Bytes | Same |
| Hard Disk | 1.6 G Bytes | Same |
| Display | SVGA | Same |
| Transmitters: | | |
| 3 channel | yes | yes |
| Tunable frequencies | 174-216 Mhz | Same |

Software:

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

| Number of patients | 4, 6, or 8 | Same |
|---------------------------------|------------------------------|--------------|
| Operating System | Windows NT<br>DOS Compatible | Same |
| Data Storage | 24 hrs of EKG/Channel | Same |
| Number of leads for Analysis: 3 | | |
| Automatic ST Analysis | yes, 12 derived leads | yes, 3 leads |
| Manual ST Analysis | no | no |

The only difference between the two Zymed systems is the extension of automatic ST Analysis to the derived 12 lead.

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 EasiView as targeted. Separate sensitivities (SE), positive predictivity (+P), and false positive rate (FPR) were examined for each database and measured for QRS, Ventricular, Couplets, Short runs and Long runs. Separate Episode Sensitivities (ESE), Episode Positive Predictivity (E+P), Duration Sensitivity (DSE) and Duration Positive Predictivity (D+P) were examined for the European ST-T(EST) database and measured for ST analysis. High heart rates to include pediatric patients were demonstrated to be within recommended guidelines in excess of 300 bom, 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.
