Philips ECG Cables and Leadwires, M16xx and M19xx Series: 3 and 5 Leads, AHA and IEC, Clips and Buttons, plus the PiCCO Main Cable M1643A
Philips M16xx/M19xx ECG cables for MP, MX, X3 monitors: M1973A, M1974A, M1968A, M1971A, M1644A, M1645A, M1675A, M1643A, AHA and IEC standards, 3 and 5 leads.
The ECG cable is the most heavily loaded accessory of a patient monitor. It connects the electrodes on the patient's body to the ECG module and takes part in almost every examination: on admission, in the operating room, in the intensive care unit, during patient transport around the clinic. The splitter is bent with every repositioning, clips and buttons take mechanical load when applied, and the cable itself is regularly treated with disinfectant solution.
Hence the practical conclusion: ECG cables fail faster than the monitoring station itself, and the demand for them is constant. One damaged wire zeroes out the entire ECG channel, so a department should keep a spare leadwire cable and one trunk cable.
This article covers sixteen items from the MediAccessori catalog for Philips monitors: fifteen leadwire and trunk ECG cables of the M16xx and M19xx families, as well as the PiCCO main cable M1643A. For each item the official catalog description, compatible equipment, an approximate price in rubles and stock availability are given. At the end there is a summary matrix, selection rules for the task and typical faults.
1. Terminology: leads, splitter and trunk cable
The catalog cards use three closely related concepts. It is useful to distinguish them before ordering, because selection is built on exactly these features.
- •Leadwire cable (ECG cable) — a product that connects to the ECG module and carries the electrodes. In this selection this type includes M1973A, M1974A, M1644A, M1645A, M1968A, M1971A, M1675A, M1673A, M1674A, M1672A, M1671A, M1624A and M1626A.
- •Trunk cable — an extended 2.7 m trunk. In the catalog, M1668A (5-lead) and M1669A (3-lead) are described this way; both are compatible with both AHA and IEC.
- •Splitter — the assembly where the trunk divides into individual leadwires. It can be clamp-type (grabber) or button-type; the official catalog descriptions state the splitter type directly.
Another feature is the connector type. For most items in the selection it is a single-row middle connector, while the neonatal M1624A and M1626A have a round connector in a shielded design.
2. Five-lead cables: a complete set for analysis
Five leads give a complete picture for chest lead analysis and are used in intensive care units and operating rooms.
PN M1973A — clamp-type, AHA standard
Official catalog description: Original Philips ECG cable, 5-lead, clamp-type splitter with interference protection, AHA standard (V — brown, RA — white, LL — red, LA — black, RL — green), single-row middle connector

Within the five-lead group, items differ in two features — clamp-type or button-type splitter and AHA or IEC standard. This covers a department's needs with any type of electrode used.
3. Three-lead cables: routine monitoring
Three leads are the basic option for continuous monitoring where a full set of chest leads is not required. The splitters in this group are generally 1 m long, while 0.7 m models with a round connector are provided for newborns.
PN M1675A — button-type, 1 m, AHA standard, with interference protection
Official catalog description: Original Philips ECG cable, 3-lead, button-type splitter with interference protection, 1 m, AHA standard (RA — white, LL — red, LA — black), single-row middle connector

Approximate price: 2,970 ₽ · Availability: 100 pcs.
The neonatal M1624A and M1626A are the most affordable items in the selection, but they should be chosen strictly by purpose: the 0.7 m length and shielded design are intended for work in a neonatal department.
4. Trunk cables M1668A and M1669A
Trunk cables extend the connection and allow the monitor to be positioned further from the patient.
PN M1668A — 5-lead, 2.7 m, AHA and IEC
Official catalog description: Original Philips ECG trunk cable, 5-lead, 2.7 m, compatible with AHA standards (V — brown, RA — white, LL — red, LA — black, RL — green) and IEC (C — white, R — red, F — green, L — yellow, N — black), single-row middle connector
Approximate price: 10,065 ₽ · Availability: 100 pcs.
PN M1669A — 3-lead, 2.7 m, AHA and IEC
Official catalog description: Original Philips ECG trunk cable, 3-lead, 2.7 m, compatible with AHA standards (RA — white, LL — red, LA — black) and IEC (R — red, F — green, L — yellow), single-row middle connector
Approximate price: 7,755 ₽ · Availability: 100 pcs.
The key difference from the splitters is universality in color coding: both M1668A and M1669A are described in the catalog as compatible with two standards at once. For a department where staff composition and equipment change, this is a practical reserve item.
5. PiCCO main cable M1643A
PN M1643A — PiCCO main cable, 4.8 m
Official catalog description: Original Philips PiCCO main cable for the monitor, 4.8 m
Compatibility: For Philips PiCCO modules M3014A, M3012A, 867040, 867039, etc.
Approximate price: 21,400 ₽ · Availability: 100 pcs.
M1643A is not an ECG cable but the cable of the PiCCO hemodynamic module; it is included in the selection because it is ordered together with the monitor's cable accessories and has a separate compatibility list — modules M3014A, M3012A, 867040 and 867039. Its length of 4.8 m is the longest in the selection.
6. AHA and IEC color coding standards
| Lead | AHA (American) | IEC (European) |
|---|---|---|
| Right arm | RA — white | R — red |
| Left arm | LA — black | L — yellow |
| Left leg | LL — red | F — green |
| Right leg | RL — green | N — black |
| Chest lead | V — brown | C — white |
The table is built from the official descriptions of the catalog items. For three-lead cables only three working leads are indicated: for example, M1671A — RA/LL/LA, and M1672A — R/F/L.
Practical rule: the splitter type and color coding must match what is already used in the department. Mixing AHA and IEC within one department is inconvenient for staff and increases the risk of error when applying electrodes.

The table is built from the MediAccessori catalog cards. Final compatibility for a specific monitor model and revision is confirmed by a service engineer.
8. How to choose a cable for the task
Practical selection rules:
- •By number of leads. Three leads — routine monitoring (M1671A, M1672A, M1673A, M1674A, M1675A). Five leads — where a complete set is needed for chest lead analysis (M1968A, M1971A, M1973A, M1974A, M1644A, M1645A).
- •By electrode type. Clip electrodes — clamp-type splitter; button electrodes — button-type. This is the main feature that most often causes ordering mistakes.
- •By marking standard. AHA for those working with the American system, IEC with the European one. The AHA and IEC items in the selection are paired, which simplifies fleet replacement.
- •By length. Splitters — 1 m, trunk cables — 2.7 m. If the monitor is far from the patient, a trunk cable is used.
- •By patient. For newborns — M1624A and M1626A: 0.7 m, shielded design, round connector.
9. Typical faults and care
- •The ECG channel shows no signal or shows noise — check the integrity of the leadwire and the bend point at the splitter; if the insulation is damaged, replace the cable.
- •Intermittent breaks when the patient moves — typical of a wire broken inside the insulation near the middle connector; such a cable cannot be repaired.
- •Interference on all leads at once — check patient grounding and the condition of the electrodes, as well as how firmly the connector sits in the module.
- •The connector does not lock into the module — check that the connector type matches and whether the contacts are contaminated.
- •The cable is too short during transport — solved with a 2.7 m trunk cable (M1668A or M1669A), not with extension leads of unknown origin.
Care is simple: process according to the department protocol, do not bend the cable at the connectors, store without load on the wires and do not pull on the splitter when removing.
10. How to plan the purchase
A scheme for a department with Philips monitors:
- •permanent reserve — one leadwire cable per 2–3 beds: 3-lead (from 2,970 ₽ for M1626A and 5,247 ₽ for M1671A) or 5-lead (from 8,118 ₽ for M1968A);
- •trunk cables — M1668A (10,065 ₽) for five-lead beds and M1669A (7,755 ₽) for three-lead beds;
- •neonatology — M1624A (4,158 ₽) and M1626A (2,970 ₽) separately from the adult fleet;
- •standardization — 5 leads for AHA (M1973A, 10,890 ₽) or for IEC (M1974A, 10,890 ₽) according to the department profile;
- •PiCCO module — M1643A (21,400 ₽) as a reserve item for the hemodynamic module.
All items in the selection are available in stock at 100 pcs., which makes it possible to cover the needs of several departments with one delivery and plan consumption for a year.
