Contec Dynamic 12 Channel 24 Hours ECG/EKG Holter Recorder Systems Monitor Software Analyzer

Introduction
Dynamic ECG Systems adopt 12-lead system of international standard, which can continuously record ECG waveform for 24-hour (high energy battery) and analyze ECG waveform by the PC software. It is applicable for use in medical institution and community.
Function
1)Adopt 12-lead system of international standard, continuously record ECG waveform up to 24-hour.
2)Sync analysis for 12-lead, and any channels can be selected as the main analysis channel, which ensures that QRS waveform can be found accurately, and no distortion.
3)With more than 10 templates(such as atrial premature beat, ventricular premature beat, long interval, atrial fibrillation, etc.) and many user-defined modules, which can almost distinguish any kind of pathologic waveforms.
4)Flexible atrial fibrillation analysis, which ensures that physicians can use the whole or segmented AUTO/manual analysis, more accurate in atrial fibrillation analysis.
5)All pacemakers(such as AAI, VVI, DDD etc.) can be analyzed by the powerful pacemaker analysis function.
6)Single or full-lead ECG in any time bucket can be reviewed by the fast review analysis function.
7)With analysis functions for 5-minute, 1-hour and whole heart rate variability.
8)One-key print, convenient and fast to print the reports.
9)The death risk in patients with myocardial infarction can be predicted by the "HRT" analysis function.
10)“T-Wave alternation” is an important index to predict the malignant arrhythmia and sudden cardiac death.
11)With QTD(QT dispersion), VCG(vector cardiogram), VLP(ventricular late potential) and TVCG(time vector cardiogram) analysis modules, more valuable in analysis report.
