Key Features

📊 Simultaneous 12-Lead ECG Acquisition

The E3 collects all 12 leads simultaneously, providing a complete view of cardiac electrical activity in a single capture. Supports both routine 12-lead and Cabrera-lead waveform display. Advanced digital signal processing—including AC filter, DFT filter, EMG filter, and Low-pass Filter—effectively eliminates interference and baseline drift, delivering high-quality, artifact-free ECG waveforms.

🖨️ High-Resolution Thermal Printing System

Built-in thermal-array printing system with 8 dots/mm resolution delivers clear, accurate ECG waveforms with no adjustment required. Frequency response up to 150Hz ensures high-fidelity waveform capture.

📊 Comprehensive Waveform Display

Display 3/6/12-lead ECG waveforms on one screen alongside print mode, sensitivity, paper speed, and filter status—all on one screen for convenient contrastive diagnosis.

🖨️ Versatile Printing with Multiple Formats

Supports a comprehensive range of printing modes and formats to meet diverse clinical needs:

• Auto 1×12, Auto 1×12+1 – Full 12-lead options

• Auto 2×6, Auto 2×6+1 – 6-lead × 2 rows with rhythm lead

• Auto 3×4, Auto 3×4+1 – 3-lead × 4 rows with rhythm lead

• Auto 4×3 – 4-lead × 3 rows

• Auto 3-2+1, Auto 3-2 – Additional auto-format options

• Rhythm 4, Rhythm 3, Rhythm 2 – Rhythm lead printing

• Manual mode – Customizable printing

Printed content includes time, paper speed, sensitivity, calibration signal, lead name, filter state, and patient information. Additional settings include printed waveform length, output measurement parameters, diagnostic conclusion, superposition QRS waveform, histogram, trend chart, and interval list—with time print function to meet different clinical requirements.

🤖 Auto-Measurement & Auto-Interpretation

The E3 automatically measures and interprets routine ECG parameters, providing instant measurement results and auto-diagnosis conclusions for:

• 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.

🫀 Pacing ECG Detection

The E3 features pacing ECG detection, ensuring accurate interpretation even in patients with pacemakers.

📂 Case Database Management

Built-in memory allows convenient storage, review, and statistical analysis of patient cases.

🎯 Flexible Rhythm Lead Selection

Freely select the rhythm lead to conveniently observe and monitor abnormal heart rhythms.

🔋 Dual Power Supply with Long Battery Life

Operates on AC/DC power (adapts to AC 50/60Hz) with a built-in rechargeable lithium battery, charging circuit, and perfect over-current and over-voltage protection circuit. This extended battery life makes the E3 ideal for home visits, community health screenings, and mobile medical examinations.

⚠️ Smart Alerts & Prompts

Automatic prompts for "electrode-off" and "out of paper" ensure uninterrupted operation and reliable results.

⌨️ External Device Support

Support for external USB keyboard, code scanner, printer, and USB storage device connectivity expands workflow flexibility.

🌍 Multi-Language Interface

Supports 7 languages—Chinese, English, Turkish, Portuguese, German, Russian, and Kazakh—making it suitable for international medical practices.
