1 Scope

The order applies to the following two types of dynamic (movable) electrocardiograph initial verification, subsequent verification and make With the test. a) continuous recording, analysis and electrocardiogram achieve full playback. It may be recorded after storage back to the stand-alone workstation Caving or recorded, analyzed simultaneously. b) continuous analysis but only a part of the record, does not provide full playback. This procedure does not apply to not provide continuous analysis of intermittent event recorders.

2 Terms and definitions

2.1 ECG electrocardiogram (ECG) Cardiac potential visual record. 2.2 dynamic (movable) ECG machine ambulatoryelectrocardiographs (AECG) By the portable recording and playback apparatus composed of either should have analytical capabilities. 2.3 portable recorder (recorder) ambulatoryrecorder (recorder) By the ECG recording device carried by patients, the ECG electrodes connected to the line for long-time recording or recording and sub Analysis of ECG of the patient. 2.4 playback device playbackequipment Mobile recording stores data for display (or analysis) and text processing apparatus.

3 Overview

Dynamic (movable) ECG machine can continuously for 24 hours or more records in the patient's natural state tee Channel or multi-channel ECG signal by means of a computer for display, analysis and processing, and found all kinds of arrhythmic events ST segment abnormalities, provide an important basis for clinical diagnosis and treatment. Dynamic (movable) ECG machine is usually divided into two types. 1) for continuous recording and analysis Dynamic ECG a) conventional dynamic electrocardiogram machine, the first recording ECG signals, and then by an independent workstation for analysis and processing; b) real-time dynamic ECG, recorded and analyzed simultaneously. 2) Continuous analysis but some dynamic ECG recording type a) In the course of the entire ECG only on important events or specific ECG recording; b) in the whole process of real ECG recording ECG, but only time and generate reports to amplitude compression formats.

4 metering performance requirements

4.1 Maximum input range Subject dynamic (movable) ECG machine (hereinafter referred to as the subject device), each channel should be able to respond and show
