Feature
1)USB high-speed transmission.
2)Sync collection of 12-lead ECG, BP and SpO2 (optional) data for 24 h at least.
3)Comprehensive analysis of ECG and BP.
ECG
1)Display and print ECG waveform at any time during collection.
2)Multi - lead overlay analysis, any lead can be selected for analyzing, more accurate to search QRS wave.
3)Histogram analysis function, interval, interval ratio, voltage, QRS width, QRS area and HR histogram can be selected for analyzing.
4)Scatter plot (including density and mixed scatter plot) analysis function.
5)Atrial fibrillation analysis function adopts the mode of combining time scatter plot and Lorenz scatter plot, intuitive to display the location of atrial fibrillation event, convenient to positioning for diagnosis.
6)With the functions of arrhythmia, bradycardia and ST-T analysis.
NIBP
1)With the functions of 24 h automatic cycling BP measurement and setting measurement interval.
2)BP data review and report print functions.
3)Measurement of systolic pressure, diastolic pressure and mean pressure.
SpO2
1)Measurement of SpO2 and PR.
2)SpO2 trend chart review and print functions.
