ECG90A is an electrocardiograph sampling 12-lead ECG signal simultaneously and printing ECG waveform with thermal printing system, which features in, recording and displaying ECG waveform with manual or auto mode, measuring and diagnosing ECG waveform parameters automatically, prompting for "Lead off" and "Lack of paper", optional interface languages(Chinese/English), case database management. Main Features ?2.83 color LCD(resolution: 320×240) displays ECG waveform and working state clearly and comprehensively. Conveniently operate with touch and function keys. ?Sync collection for 12-lead ECG, digital signal processor, to get higher quality ECG waveforms via AC filter, baseline filter andEMG filter of ECG signal. ?Adopt high-resolution thermal array output system(8dot/mm), no need for any adjustments. Recording frequency: up to 150Hz. ?Display 3/6/12-lead ECG, print mode, sensitivity, paper speed, filter state in a screen, convenient for contrastively diagnosing. ?Particular and high-accurate digital filter eliminates baseline drift, no distortion to ECG waveform, greatly enhances anti-baseline drift capacity, convenient for waveform judgement. ?Real-time and continuously record the clear and accurate ECG waveform and annotation character(including lead mark, sensitivity, paper speed and filter status, etc.). ?With the functions of auto-analysis and auto-diagnosis for routine ECG parameters, provide measurement results and auto-diagnosis conclusion for HR, P-R interval, P Duration, QRS Duration, Q-T interval, Q-Tc, P Axis, QRS Axis, T Axis, R(V5), S(V1), R(V5)+S(V1), etc. which reduces the doctors burden.
