Intended Use

The ECG Holter evaluation software, MT-200, is an analysis software used for the analysis and evaluation of Holter ECG recordings. The Holter recordings are used for the diagnostics of symptomatic and asymptomatic arrhythmias, i.e. bradycardia, tachycardia, diagnostic of arrhythmias in patients with coronary artery disease, in patients after reanimation, in patients with different diseases such as cardiomyopathy, high blood pressure, long QT syndrome. A Holter ECG recording is also used for clarifying palpitations or syncopes and attacks of dizziness or for controlling medical therapies, or after operative treatments such as bypass operations or PTCA. The ST segment analysis of a Holter ECG is used for the detection of symptomatic or asymptomatic ischemias.

Device Story

MT-200 is ECG analysis software for Holter recordings; processes data from solid-state recorders to detect arrhythmias and ischemic episodes. Operates on Windows 95 PC; used by clinicians to evaluate symptomatic/asymptomatic patients. Transforms raw ECG signals into diagnostic reports; performs ST-segment analysis. Output assists physicians in diagnosing cardiac conditions, clarifying symptoms like syncope/palpitations, and monitoring therapy efficacy or post-surgical recovery. Benefits include automated detection of cardiac events, facilitating clinical decision-making for patient management.

Clinical Evidence

Bench testing only. Performance evaluated using standard AHA and MIT arrhythmia databases; classifications compared against database annotations. ST-T analysis validated using ESC ST-T database; ST-segment deviations compared against two independent observers. Results showed absolute difference between paired values < 0.1 mV, with differences > 0.1 mV occurring in ≤ 2% of measurements. All tests passed.

Technological Characteristics

Software-based ECG analyzer; runs on IBM-compatible PC (486, 66 MHz, 16 MB RAM, 100 MB HDD). Compatible with Windows 95. Inputs from solid-state Holter recorders. Performs arrhythmia detection and ST-segment analysis. Connectivity via standard PC peripherals (VGA monitor, laser printer).

Indications for Use

Indicated for analysis of Holter ECG recordings in patients of all ages, genders, and races to diagnose symptomatic/asymptomatic arrhythmias (bradycardia, tachycardia) and ischemic episodes. Used for patients with coronary artery disease, cardiomyopathy, high blood pressure, long QT syndrome, or post-reanimation; also for clarifying palpitations, syncope, dizziness, monitoring medical therapies, or post-operative follow-up (bypass/PTCA).

Regulatory Classification

Identification

A programmable diagnostic computer is a device that can be programmed to compute various physiologic or blood flow parameters based on the output from one or more electrodes, transducers, or measuring devices; this device includes any associated commercially supplied programs.

### Description of Submitted Device A4

The ECG Holter evoluation software, MT-200, is an analysis software used for the analysis and evaluation of Holter EOG recordings. The Holter iscoralings are used for the diagnostics of symptomatic and asymptomatic arrhythings, i.e. bradyeardia, tachycardia, diagnastic of arthythinias in pattents with coraniary artery disease, in cardiomopathy, high blood pressure, long QT syndrome,

A Holter ECG recording is also used for clarifying palpitations or syncopes and attacks of aliziniess or for controlling medical theraples, or after operative treatments such as bypass operations or PTCA. The ST segment analysis of a Holter ECG is used for the detection of symptomatic or asymptomatic Ischemics.

The software runs on Windows™ 95.

#### Non-Clinical Tests B1

# Data related to software quality

SCHILLER has reviewed the MT-200 Analyzer Software development process following the quideline "reviewer quidance for computer controlled medical devices undergoing 510 (k) review".

All tests are passed.

#### B2 Clinical Tests

To evaluate the performance of arthythmia detection of the MT-200 program, the AHA and MIT data bases were used and the annotations in the databases compared with the automatic analysis carried out by the MI-200 program.

# Method

A normal analysis of the AHA and MIT records was carried out by the MT-200. The classifications given by the MT-200 were then compared with the annotated classifications of the data bases.

The results of the comparison were alven in tabular form. The procedure and limits described In ANSVAAMI EC 38-1994 were used.

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

# SCHILLER ITZERLAND

For the evaluation of the ST-T analysis the ESC ST.T. database was used. The STsegment deviations measured by the MT-200 were compared to the deviations measured by two independent observers.

The limits set up for test were not violated.

The absolute difference between paired values (reader MT-200) is less than 0.1 mV. The total number of differences greater than 0.1 mW Is less than or equal to 2% of the total number of measurements.

All tests are passed

#### ВЗ Conclusions from Tests

The fulfillment of the above standards ensures the safely and effectiveness of the submitted device. We consider the submitted device to be as safe and effective as the Predicate Brentwood Rhytmscan Precision CS-6000 (K914577) Device.

All tests are passed.
