Holter ECG Cable –Designed for long-term ambulatory ECG monitoring with high comfort and ultra-low motion noise

Technical and specification details

1.Engineered for Reliable Long-Term ECG Monitoring
Holter ECG cables are essential components in modern ECG monitoring devices, portable ECG monitors, and wearable ECG systems.
By focusing on motion noise suppression, flexible materials, and stable signal transmission, Holter ECG cables enable accurate ECG data collection outside traditional clinical settings, supporting the growing demand for home-based and wearable ECG monitoring solutions.
2.A Growing Trend: From Hospital Monitoring to Everyday ECG Tracking
With the rapid development of portable ECG monitors, wearable ECG monitoring devices, and home ECG monitors, Holter ECG systems are increasingly used outside traditional hospital environments.
Key drivers behind this trend include:
•Long-term ECG monitoring without hospitalization
•Home-based and outpatient cardiac screening
•Continuous ECG monitoring during daily activities
•Lightweight wearable ECG devices for early arrhythmia detection
As a result, Holter ECG cables must perform reliably in dynamic, uncontrolled environments, far beyond the conditions of stationary hospital monitoring.

Compliance and Certification

1.Connector Interfaces for Portable ECG Devices
Holter ECG cables are designed to interface with portable ECG recorders and wearable ECG monitors, rather than stationary bedside monitors.
Design considerations include:
•Compact device-side connectors
•Secure locking to prevent accidental disconnection during movement
•Strain-relief structures optimized for repeated bending
Patient-side terminations may include snap, tab, or pin-style electrodes, selected to balance signal stability and ease of electrode replacement during long-term monitoring.

Core Competencies and Differentiation

1.Low-Motion-Noise Design for Wearable and Ambulatory ECG Monitoring
Holter ECG cables are specifically engineered for ambulatory and wearable ECG monitoring, where patients remain active during long-term ECG recording. Unlike bedside or integrated ECG cable systems, Holter cables must maintain signal stability under continuous motion, making motion-noise control the most critical engineering requirement.
Holter ECG cables are widely used in Holter ECG monitoring devices, wearable ECG monitors, portable ECG recorders, and home ECG monitoring systems, supporting both clinical diagnostics and daily-life cardiac monitoring.
2.Motion Noise–The Primary Engineering Challenge
Compared to integrated ECG cables used in bedside monitoring, Holter ECG cables face significantly higher motion-induced interference.
Sources of noise during ambulatory ECG monitoring include:
•Body movement and cable swing
•Friction between internal conductors and jacket materials
•Micro-vibrations at the electrode interface
•Changes in cable bending radius during motion
For this reason, motion noise requirements for Holter ECG cables are typically more stringent than for integrated or trunk-and-lead ECG cable systems.
3.Advanced Low-Noise Cable Structures
To minimize motion artifacts and ensure accurate ECG waveform capture, Holter ECG cables may incorporate multiple noisereduction techniques:
•Ultra-fine stranded conductors to enhance flexibility
•Semi-conductive or low-triboelectric coatings on individual cores
•Optimized conductor lay length to reduce micro-movement
•Optional shielding strategies designed to suppress external interference without increasing stiffness
In some designs, each conductor may include an additional semi-conductive layer to dissipate static charge generated during movement, significantly reducing triboelectric noise.
4.Lightweight and Wearable-Focused Materials
Material selection for Holter ECG cables prioritizes low weight, softness, and long-term wearing comfort.
Common jacket materials include:
•Soft TPU or TPE compounds for flexibility and durability
•Ultra-soft formulations for skin-adjacent wearable applications
•Thin-wall constructions to reduce overall cable mass
Compared to integrated ECG cables, Holter cables typically use lighter and thinner jacket designs, even at the expense of mechanical robustness, to improve user comfort during extended wear.
5.Holter ECG Cable vs. Integrated ECG Cable – Engineering Perspective
While both cable types support ECG monitoring, their engineering priorities differ significantly:
Holter ECG Cable
•Designed for ambulatory and wearable ECG monitoring
•Strict motion-noise control requirements
•Lightweight and flexible construction
•Optimized for continuous ECG monitoring during daily activity
Integrated ECG Cable
•Designed for bedside or hospital ECG monitoring
•Focus on system simplicity and durability
•Lower exposure to motion-induced noise
•Optimized for clinical workflow and ease of use
These differences require distinct design strategies rather than simple structural modifications.
