Key Features

📊 Simultaneous 12-Lead ECG Acquisition

The E3M collects all 12 leads simultaneously, providing a complete view of cardiac electrical activity in a single capture. Advanced digital signal processing—including power frequency filter, baseline filter, and EMG filter—effectively eliminates interference and baseline drift, delivering crisp, artifact-free waveforms.

🖥️ 3.5" TFT Color Display

The high-resolution color screen displays 1/3/6/12-lead ECG waveforms alongside critical information—print mode, sensitivity, paper speed, and filter state—all on one screen for convenient contrastive diagnosis.

🖨️ Versatile Thermal Printing System

Built-in thermal printing system supports multiple printing modes and formats:

• Manual mode – Customizable printing

• Auto 4×3, Auto 3×4+1, Auto 3×4 – Multiple auto-format options

• Auto 2×6+1, Auto 2×6 – Flexible rhythm lead printing

• Waveform length adjustable – Meets different clinical requirements

• Timed print function – Automated scheduled printing

🤖 Auto-Analysis & Auto-Diagnosis

The E3M automatically measures and diagnoses routine ECG parameters, providing instant measurement results and diagnostic conclusions:

• Heart Rate (HR)

• P-R Interval, P Duration, QRS Duration, T Duration

• Q-T Interval & Q-Tc

• P Axis, QRS Axis, T Axis

• R(V5), S(V1), R(V5) + S(V1) amplitude

This powerful feature significantly reduces the doctor's diagnostic burden and accelerates clinical workflow.
