ECG Holter system includes ECG recorder and software connectable to a computer system or laser printer. The recorder has built-in flash storage media to increase memory capacity. The sampling rate of 1,000 sampling/sec has improved the quality of waveform. Accuracy of the system is ensured by AHA and MIT data.Features: - windows software interface (GB, IT, PL, PT, RU) - quick and accurate analyzing system - special editing system of R point - perfect analysis function of ST segment - analysis function of T wave of all channels and T wave trend graph - review of ECG trend graph - analysis system of HR variability, providing regular SDNN, SDANN, RMSSD, LF, HF, time domain and frequency domain - QT analysis - acquire pacing ECG directly without separate channel; Also have the functions of VCG, VLP, TVCG, HRT, TWARecorder: - 12 channel Synchronized ECG Acquisition - small ECG recorder with OLED colour screen to display real time ECG waveform and review storage data. - capacity up to 2G - selectable sampling rate, 200, 500, 1,000 sampling/sec - sampling accuracy: 12 bit - built-in FLASH storage media, to prevent the flash card from damage due to repeated insertion and pull out - USB interface - operating system: Win 98, 2000, XP, 7, 8, 10Technical Specifications • Scale voltage: 1mV±5% • Standard sensitivity:10mm/mV±5% • Noise level: =30µV • CMRR: =60dB • Frequency response: 10Hz as benchmark, 0.5Hz~55Hz; -3dB • Time constant: >3.2s • Scan speed: 25mm/s±5% • Enduring polarization voltage: ±300mV • Least measurence signal: 50µV p-p • Interference between channels: scan track deflection (result from interference between channels) <0.5mm • Product safety type: type B (internally powered) • Size: 111 (L) x60 (W) x25 (H) mm • Net weight: 105g (without battery)Standard accessories • 1 Holter recorder • 1 CD with software (GB, IT, PL, PT, RU) • 10 leads patient cable • 10 disposable ECG sensor • 1 pouch for hanging recorder • 1 USB cable for data downloads • Instruction Manual (GB, IT)
