7-lead patient cable for Holter ECG recorder
Description
The Welch Allyn 7 Lead Patient Cable for HR-100 Holter ECG (part number 704548) is a dedicated 7-lead patient cable designed for use with the Welch Allyn HR-100 Holter Recorder. It provides the electrical connection between surface ECG electrodes on the patient and the HR-100 recorder, enabling 2- or 3-channel ambulatory ECG recording for up to 24–48 hours. This IEC-configured cable features seven individual leads terminating in snap-style electrode connectors and is engineered to be robust, flexible and reliable for long-term ambulatory monitoring applications.
Bnefits
Specifically designed and validated for use with the Welch Allyn HR-100 Holter Recorder, ensuring full compatibility and reliable signal acquisition.
Provides 7-lead ECG connectivity, supporting 2- or 3-channel Holter recording configurations as implemented in the HR-100 system.
IEC-configured patient cable variant (704548) compatible with IEC colour-coding conventions used in many international markets.
Flexible yet durable cable construction suitable for extended ambulatory monitoring periods (24–48 hours) with minimal artefact from normal patient movement.
Snap-style electrode connectors enable quick attachment and removal of disposable Holter electrodes.
High-quality shielding and insulation help maintain signal integrity and minimise electrical noise during recording.
Designed as a serviceable accessory within the HR-100 Holter System, allowing cost-effective replacement of worn or damaged cables without replacing the recorder.
Backed by Welch Allyn / Hillrom quality standards and integration into the Holter Systems portfolio, including Office Holter and Expert Holter software solutions.
Indications
Use as a patient connection cable with the Welch Allyn HR-100 Holter Recorder for ambulatory ECG monitoring.
Acquisition of up to 3 channels of ECG waveform data via surface electrodes during 24–48 hour Holter monitoring.
Screening for and documentation of ECG rhythm disturbances such as arrhythmias over extended recording periods.
Use in cardiology clinics, hospitals and primary care environments where HR-100 Holter monitoring is performed.
Multi-conductor insulated cable bundle with medical-grade polymer insulation and outer jacket (PVC or similar material as specified by Welch Allyn).
Seven individual conductor wires terminating in snap-style electrode connectors designed for use with disposable Holter electrodes.
Moulded plastic strain-relief and connector housing at the recorder end, compatible with the HR-100 Holter Recorder input connector.
Internal shielding and twisted-pair conductors (where implemented) to reduce electrical interference and noise.
Materials are latex-free in line with typical Welch Allyn cardiology accessories (no natural rubber latex components in patient-contact areas).
Formulation
Reusable, non-sterile 7-lead patient cable accessory for Holter ECG systems.
Configured for IEC lead designations (704548 IEC version) for use in markets following IEC electrode colour coding.
Single integrated cable assembly with fixed leads designed to be connected at one end to the HR-100 recorder and at the other end to surface electrodes via snap connectors.
Optimised cable length to allow standard Holter electrode placement and patient mobility while wearing the HR-100 recorder in a carrying case.
Packaging
Supplied as a single 7-lead patient cable per pack.
Packaged in protective primary packaging (e.g., polybag or tray) within a labelled carton identifying Welch Allyn, HR-100 compatibility and part number 704548.
Delivered as a non-sterile accessory; Holter electrodes and HR-100 recorder are ordered separately.
May be supplied as part of certain HR-100 Holter kits (e.g., HR-100 recorder with 7-lead cable and carrying case) or as a standalone replacement part.
Usage
Use only with the Welch Allyn HR-100 Holter Recorder or systems explicitly specifying compatibility with the 704548 7-lead patient cable.
Before each use, visually inspect the cable, connectors and lead wires for cracks, breaks, exposed conductors, kinks or other damage; do not use a damaged cable.
Connect the recorder-end connector securely to the HR-100 Holter Recorder, ensuring it is fully seated and locked according to the recorder’s instructions.
Prepare the patient’s skin and apply Holter electrodes according to the HR-100 Holter System manual, using IEC-designated lead positions that correspond to the cable’s colour coding.
Attach each snap connector on the cable leads firmly to the corresponding disposable electrodes, confirming good mechanical and electrical contact.
Verify signal quality and lead integrity using the HR-100 recorder’s display or associated Holter software prior to starting the recording.
Secure the cable and recorder to minimise tension on the electrodes and reduce motion artefact, typically using tape or straps as described in the HR-100 Directions for Use.
Instruct the patient on how to wear the recorder and cable during the monitoring period, including precautions to avoid pulling or damaging the cable and to avoid getting the system wet.
After the monitoring period, disconnect and remove the cable from the patient and recorder, discard used electrodes, and clean the cable according to Welch Allyn’s cleaning and disinfection recommendations (usually wiping with approved disinfectant wipes; do not immerse unless specified safe).
Allow the cable to dry completely before storage, then store in a clean, dry location, coiled loosely to avoid kinking or overstressing the conductors.
Contraindications
Use with devices other than the Welch Allyn HR-100 Holter Recorder or systems not specified as compatible with the 704548 cable.
Use of a visibly damaged or degraded cable (e.g., cracked insulation, exposed wires, broken connectors).
Application in settings where continuous monitoring is required for life-support decisions; the HR-100 Holter System is intended for diagnostic ambulatory monitoring, not real-time critical care monitoring.
Use in environments with significant electromagnetic interference without adequate shielding or mitigation, which could compromise ECG signal quality.
Adverse Effects
If electrodes and leads are not secured properly, rubbing or traction on the skin may cause local irritation, redness or minor discomfort at electrode sites (related primarily to electrodes and tape rather than the cable itself).
Incorrect routing or securing of the cable may increase the risk of the patient tripping or pulling on the recorder, potentially causing minor injury or device damage.
Inadequate cleaning or disinfection of the cable between patients could contribute to cross-contamination if not managed according to infection-control policies (the cable itself is non-invasive but may contact skin or clothing).
Storage Conditions
Store the cable in a clean, dry environment at normal room temperature, within the environmental ranges specified for the HR-100 Holter System.
Avoid exposure to excessive heat, cold, direct sunlight or high humidity that could degrade insulation or plastic components.
Do not store the cable with heavy objects placed on top of it or in a tightly kinked or sharply bent configuration; loosely coil the cable to prevent strain on conductors and insulation.
Keep away from sharp edges, chemicals and solvents that may damage the cable jacket or connectors.
Store in a dedicated accessory compartment or case with the HR-100 recorder where possible to prevent misplacement or accidental damage.
Duration
Not applicable \u2013 this product is an ECG accessory and not a therapeutic device; it is used for the duration of the Holter monitoring period (typically 24\u201348 hours) in conjunction with the HR-100 recorder.
Onset
Not applicable \u2013 the cable provides an electrical connection for signal acquisition and has no pharmacological or direct clinical effect; ECG signal capture is available immediately once correctly connected and the recorder is started.
