Contec ECG90A Handheld Digital ECG 12-Lead EKG Electrocardiograph Auto-Analysis

The Contec ECG90A is an ECG (Electrocardiograph) device which can collect a 12-lead ECG signal and print waveform using the built-in thermal printer.
It features include: recording and displaying ECG waveform in AUTO/Manual mode, measuring and diagnosing ECG waveform parameters automatically, prompting for "Lead off" or "Lack of paper", optional interface languages(Chinese/English), case database management.

Features:

1. Sync collection for 12-lead ECG, adopt digital signal processing technology and get high-quality ECG waveform via power frequency filter, baseline filter and EMG filter of ECG signal.
2. Particular and highly-accurate digital filter eliminates baseline drift, no distortion to ECG waveform, greatly enhances anti-baseline drift capacity, convenient for waveform judgment.
3. Display of 3/6/12-lead ECG, print mode, sensitivity, paper speed and filter state, etc. on one screen, convenient for diagnostic purposes
4. Real-time and continuously records the clear and accurate ECG waveform with annotation characters (including lead mark, sensitivity, paper speed and filter state, etc.).
5. Adopt high-resolution thermal printing system(8 dot/mm), no need for any adjustments. Recording frequency: up to 150Hz.
6. 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 doctor’s burden.
7. Optional SD card stores up to 100 cases - ideal for review by doctors
8. In review mode, case waveform stored can be checked, measurement parameter and diagnosis information can be automatically analyzed.
9. Two languages(Chinese or English) interface and report.
10. Optional ECG-Sync software, connect with PC by USB2.0 interface to form an ECG workstation, collect real-time data to the software for analyzing and printing the report, and cases stored in the ECG device can be uploaded to PC.
11. Power supply: AC/DC, and in optimal DC state, built-in rechargeable lithium battery can continuously work for 4 hours, print up to 90-minute and 150-ECG, which meets the requirements of visiting a patient at home for examination. The rechargeable lithium battery is removable, which is convenient for user to replace and charge at any time.
