Contec ECG300G 3-Channel ECG Machine

Description

Lead Configuration and Waveform Capture: Multi-Lead ECG Acquisition The Contec ECG300G supports simultaneous 12-lead ECG collection (I, II, III, aVR, aVL, aVF, V1–V6) with 3-channel real-time display for comprehensive cardiac electrical activity recording. This enables detailed visualization of PQRST complexes across multiple views, facilitating detection of arrhythmias, ischemia, or conduction delays, while the sync collection mode ensures artifact-free traces even in ambulatory settings.

Parameters Measured: Automatically measures and interprets 12 key ECG parameters: heart rate (HR), PR interval, P duration, QRS duration, QT/QTc interval, P/QRS/T axis, R(V5) amplitude, S(V1) amplitude, and R(V5)+S(V1) for ventricular hypertrophy assessment. Generates high-resolution waveforms with baseline wander and EMG filtering, plus manual override for complex cases, providing diagnostic aids for conditions like atrial fibrillation or bundle branch blocks with CV <5% accuracy.

Sample Requirements: Utilizes standard 12-lead limb/chest electrodes on adult/pediatric patients, requiring no sample volume—direct skin contact for venous-equivalent signal acquisition. Compatible with reusable or disposable electrodes, with lead-off detection to alert for poor contact, making it suitable for routine checkups or emergency transports without specialized prep.

Throughput: Processes up to 3 full 12-lead ECGs per hour in manual mode or automated sequences, optimized for low-volume clinics handling 10–50 tests daily. Quick 10–30 second acquisition per trace with instant printing supports on-demand testing, ideal for GP offices or visiting nurse workflows without high-throughput demands.

Technology: Employs digital signal processing with 12-bit A/D conversion and frequency response of 0.05–150 Hz for noise-resistant waveforms, including AC interference (50/60 Hz), baseline drift, and EMG filters (25/35 Hz). Thermal array printing on 80 mm roll paper captures up to 3 channels simultaneously, with pacemaker pulse detection for device patients, ensuring reliable performance per AAMI/EC standards.

User Interface and Storage: Equipped with a 3.5-inch high-resolution LCD for waveform preview, parameter review, and menu navigation, supporting up to 6 languages (English, Chinese, Spanish, etc.) for global usability. Stores up to 1,000 cases with patient demographics and full traces, accessible via USB for PC export; built-in thermal printer for 3/6/12-lead formats, with RS232 connectivity for basic LIS integration and PDF-like reports.

Reagent System: No reagents required—electrode-based acquisition with optional conductive gel for enhanced contact in dry skin cases. Includes 2 rolls of thermal paper (80 mm x 20 m) for 200+ prints, with low-cost refills; auto-prompts for paper/lead issues minimize interruptions, supporting sustainable, maintenance-free operation.

Dimensions and Portability: Compact design measuring 315 × 230 × 90 mm (W × D × H) weighs 1.9 kg, with ergonomic handle for handheld transport in ambulances or home visits. Built-in rechargeable lithium battery offers 10-hour standby or 3-hour continuous printing, operating on AC 110–240V or DC; quiet (<50 dB) in 10–40°C ambient with 30–85% humidity.
