Product definition
What Is an ECG Trunk Cable?
An ECG trunk cable, also called an ECG patient cable or ECG main cable, is the reusable monitor-side cable that connects a patient monitoring system to a detachable ECG leadwire set. It carries multiple ECG signal channels through a device-specific connector and pinout.
An ECG trunk cable is different from ECG leadwires. The trunk cable connects to the monitor, while the leadwires connect to the patient electrodes. Both components must use compatible connectors, pin assignments, lead configurations and color-coding requirements.
Available configurations
ECG Trunk Cable Configurations
The appropriate configuration depends on the monitoring system, ECG leadwire interface and intended acquisition workflow.
Commonly configured for basic rhythm and heart-rate monitoring when supported by the target system.
Supports expanded ECG monitoring configurations specified by compatible bedside or multi-parameter monitors.
A 10-electrode configuration may support 12-lead ECG acquisition when specified by the target monitoring system.
Connector, pinout, channel arrangement and leadwire interface can be built to an approved OEM drawing.

Design priorities
ECG Cable Design for Signal Integrity and Mechanical Reliability
Low-Noise Conductor Design
Fine-strand conductor structures can improve cable flexibility and help reduce motion-related electrical noise in sensitive ECG signal paths.
Optimized Multi-Core Configuration
Conductor arrangement and electrical characteristics are selected according to the lead configuration to support consistent signal transmission across multiple ECG channels.
Application-Specific Shielding
Shielding structures can be selected according to the application and signal requirements, including foil, braided or combined configurations.
Reinforced Strain Relief
Molded strain-relief structures help distribute bending and pulling stress at connector exits, improving mechanical reliability during repeated handling.
Device integration
ECG Trunk Cable Compatibility Is Model-Specific
ECG trunk cables are not universal. Compatibility depends on the monitor connector, pinout, lead configuration, leadwire interface and any device-specific identification components. A monitor brand name alone is not sufficient for product selection.
JYCMED can review projects for patient monitoring platforms from Philips, GE Healthcare, Mindray, Nihon Kohden and other manufacturers when an exact monitor model, compatible part number, interface drawing or physical sample is supplied.
Third-party brand names are used only to describe potential compatibility references. Compatibility must be confirmed for the exact device model and interface before production.
OEM / ODM manufacturing
Custom ECG Trunk Cable Manufacturing
JYCMED supports medical device manufacturers and distributors with connector matching, cable-structure review, sample verification and controlled production for custom ECG trunk cable assemblies. The final construction is documented in an approved drawing or specification before mass production.
Quality control
ECG Trunk Cable Production and Verification
- ISO 13485 quality-management production environment
- Incoming material and connector inspection
- Assembly according to controlled work instructions
- Continuity, pinout and insulation verification
- Visual, dimensional and workmanship inspection
- Production records and lot traceability
Test items, acceptance criteria and material-compliance requirements are defined by the approved project documentation and customer specification. Supplier material documentation is available in the JYCMED resources center.
Buyer questions
ECG Trunk Cable FAQs
What is the difference between an ECG trunk cable and ECG leadwires?
The ECG trunk cable is the reusable monitor-side main cable. ECG leadwires connect the trunk cable or monitor interface to the patient electrodes. Their connectors, pinout and lead configuration must be compatible.
Are ECG trunk cables universal?
No. Compatibility depends on the exact patient-monitor model, connector, pinout, lead configuration, leadwire interface and any device-specific identification components.
Does a 12-lead ECG system always use 12 patient electrodes?
No. A 12-lead diagnostic ECG is commonly derived from ten patient electrodes. The required trunk-cable configuration must follow the target monitoring system and approved interface specification.
Which information is needed to identify a compatible ECG trunk cable?
Provide the monitor brand and model, compatible part number, connector photos or drawing, pinout, lead configuration, leadwire interface and required cable length.
Can the connector, cable length, shielding and jacket be customized?
Yes. These items can be configured to an approved OEM drawing, subject to interface review, material selection and project-specific verification.
How is a custom ECG trunk cable verified before production?
Verification can include connector and pinout checks, continuity, insulation, dimensional inspection, workmanship review and other tests defined by the approved project specification.
