How to choose different types of ECG machines

As the core equipment for heart health monitoring, the ECG Machine provides important basis for clinical diagnosis by detecting myocardial electrical signals and converting them into waveform graphs. According to the number of signal acquisition and output channels, ECG machines can be divided into the following mainstream types:

Classification and technical features of ECG machines

1. Single-channel ECG machine

Basic model, only outputs 1 lead waveform each time
Realizes 12-lead step-by-step acquisition through lead switching
Equipped with intelligent microprocessor, supports automatic mode
Suitable for basic ECG screening scenarios

2. 3-channel ECG machine

Synchronously outputs 3 lead waveforms
Uses multiplexing technology to process 12-lead signals
With analog-to-digital conversion and data storage functions
Completes all lead acquisition in 4 groups
Suitable for medium-demand scenarios such as community hospitals

3. 6-channel ECG machine

Simultaneously outputs 6 lead waveforms
Only 2 prints are required to complete 12-lead reports
Uses widened printing format (wide short and long)
Supports clinical rapid comparative analysis
Suitable for routine testing in secondary hospitals

4. 12-channel ECG machine

Full lead synchronous output (6×2/3×4 format)
Standard A4 format printing (210-216mm width)
Supports multi-waveform parallel display
Clinical diagnosis efficiency increased by more than 40%
Widely used in cardiology departments of tertiary hospitals

Clinical application scenarios of electrocardiogram detection

The electrocardiogram electrodes can achieve the following medical detection functions through standard body surface positioning:

Diagnosis of abnormal heart rate (too fast/too slow/too irregular)
Early screening of myocardial ischemia
Location diagnosis of coronary heart disease and myocardial infarction
Evaluation of abnormal cardiac structure (ventricular wall thickening, etc.)
Electrolyte disorder monitoring (calcium/potassium imbalance)
Determination of the degree of coronary artery stenosis
Postoperative evaluation of pacemakers
Tracking the effect of drug treatment

How to choose a suitable ECG Machine

Model Number of channels Applicable scenarios Report features
Single channel 1 Basic screening Single lead step-by-step printing
3 channels 3 Community medical care Group output, low cost
6 channels 6 Secondary hospitals Wide report, fast comparison
12 channels 12 Tertiary hospitals A4 Full-lead simultaneous printing

Selection suggestions:

Primary medical institutions give priority to 3-channel models
Comprehensive hospitals recommend 6-channel or 12-channel models
Pay attention to the device's anti-interference ability and data storage function
Pay attention to the adaptability of consumables (printing paper specifications/electrode costs)

Industry development trends

The 2025 Medical Equipment White Paper shows that the annual growth rate of the multi-channel ECG market will reach 15.7%, and the main driving factors include:
Rising incidence of cardiovascular diseases
Demand for upgrading community medical equipment
Integration of AI-assisted diagnosis technology
Popularization of wireless remote monitoring functions
