■Quick and accurate analysis system. ■With 3 leads synchro analysis, QRS search can be more exactly. ■ There are more than 10 templates as atrial premature beat module, ventricular premature beat module, long interval module, atrial flutter module, atrial fibrillation module etc. and multiplicate User-defined templates could almost identify every kind of pathologic waveforms. ■Optional main channel. ■ Agile and exact "Atrial Fibrillation" analysis. ■The function of pacing analysis could analyse all pacemakers. ■ Many pacine modules have been added. ■ Any period of single lead or 3-leads ECG can be reviewed at any time with the function of fast waveform review and analysis. ■ The types of the analysis system of HR variability include five minutes of short ECG and one hour or 24-hour of long ECG. ■ Print report expediently. ■ Perfect function of case management. ■ With the function of ST segment analysis and general load of the disorder of the heart muscle, the physician can judge a disease or disorder of the heart muscle generally. ■"Sleep breath pause syndrome analysis", the physician could print sleep asphyxia analysis report and diagnose. ■"HRT" analysis, when the adjustable function is natural, this transitory change will be represented by the form of HRT immediately. ■15."T Wave Alternation" analysis is a important index on judging and preventing arrhythmia.
