PC Based ECG Workstation, 12 Lead USB PC SW Resting System Recorder

Introduction

The device acquires functions that include a synchronous sampling of conventional 12-lead ECG data and 3-lead vector ECG data, various forms of analysis and diagnosis, report output, and other functions. As an integrated ECG analysis system, the device can reflect the user's heart movement timely and accurate. It is applicable for ECG examination in medical and health institutions, providing an accurate and reliable basis for diagnosis. 

Features
1. Compact and portable design for Recorder, supports both Wilson and Frank lead system, with lead-off indicator. 
2. Adopt real-time sampling, display, and storage mode, with functions such as QRS waveform analyzing in real-time, HR calculation, and real-time printing, as well as multiple filter methods to avoid baseline drift and interference. 
3. Advanced ECG analysis algorithm ensures accurate auto-analyzing points and reliable auto-recognizing sort of arrhythmia, which makes the analyzing report and conclusion more valuable.
4. For clear display, ECG waveform uses anti-aliasing technology; the smart adjustment function of lead position solves the problem of overlapping waveform caused by baseline drift or high amplitude waveform. 
5. High sampling frequency (1000 Hz) ensures correct ECG waveform without distortion. High resolution in display and printout guarantees the details of the ECG waveform. 
6. With dozens of sync and continuous display/print modes, including 6x2, 3x4, 3x4+2, etc. Auxiliary tools, such as superposed waveform analysis, electronic scale editable terminology database, etc., bring much more convenience for diagnosis and clinical application. 
7. Multiple analysis functions, including conventional 12-lead ECG, Frequency Cardiogram (FCG), High-Frequency ECG, QT internal dispersion analysis, Heart Rate Variability (HRV) analysis, myocardium ischemia (STLE) analysis, Heart rate turbulence (HRT) analysis, Pacing ECG analysis, Vector Cardiogram (VCG), Time Vector Cardiogram (TVCG) and SAECG, etc. 
8. The "shortcut print" function can preview or print the whole analysis reports, and save them on PC in multimedia format (BMP, PNG, PDF, or JPG format) according to factual need
9. Support calling external procedures to obtain patient information of unknown origin, exporting HL7 aECG standard format ECG data, printing electronic reports, and sending notice to the external procedure, convenience for systems docking with hospital HIS, PACS, and others.
