Contec ECG300G Digital 12 Lead ECG Machine USB Interface is a compact, reliable electrocardiograph designed for fast, accurate cardiac assessment in clinics and hospital settings. It collects 12-lead ECG signals, displays and prints waveforms via a thermal printer, and supports AUTO and Manual operation modes to fit your workflow. Built for everyday clinical use, ECG300G emphasizes clarity, ease of use, and dependable performance.

Equipped with advanced digital signal processing, the ECG300G delivers high-quality ECG waveforms using power frequency filters, baseline stabilization, and EMG suppression. It can display 3/6/12-lead ECG on one screen, supports multiple printing formats, and offers adjustable print length and time stamps to meet diverse reporting needs. Auto-analysis and auto-diagnosis cover routine parameters, helping clinicians quickly interpret results and reduce workload. The device includes lead-off and paper availability prompts to prevent incomplete recordings.

Designed for everyday clinical workflows, the ECG300G stores up to 1000 cases in its internal memory for easy review and statistics. It features a multilingual user interface and report options, including a USB interface for convenient data transfer. With AC/DC power, it’s suitable for varied clinical environments. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Main description

The ECG300G performs synchronized 12-lead ECG data collection with a thermal printing system, enabling rapid documentation of patient findings. It supports flexible rhythm displays and print layouts, from compact 1×12 to larger multi-lead formats, making it easy to compare tracings and annotate findings. Auto-measurement of key intervals and axes (HR, P-R interval, P duration, QRS duration, T duration, Q-T, Q-Tc, P/QRS/T axes, etc.) assists clinicians in making timely decisions while reducing manual measurement effort.

Benefits & Tips

  • Get ready-to-review 12-lead ECG results quickly with auto-analysis and auto-diagnosis, saving time during patient rounds.
  • Choose from multiple print formats and paper speeds (Auto, Rhythm, Manual) to tailor outputs for reports, patient records, or referrals.
  • Utilize the built-in memory (up to 1000 cases) for efficient case review, statistics, and follow-up comparisons. Connect via USB for easy data transfer.
