The system features both automatic and manual recording modes, displaying real-time waveforms on its vivid display. Designed to optimize workflow, it automatically measures and diagnoses critical ECG parameters while offering advanced analysis tools—such as printing trend charts and P-R interval histograms—to help track abnormal heart rhythms. With its built-in thermal printing system, the ECG1200G outputs sharp, clear physical reports. It includes smart features like "Lead off" and "Lack of paper" prompts to prevent operational downtime, supports a multi-language interface, and runs on both AC and DC power source options for uninterrupted clinical use.
