FDA PRODUCT CODE · CLASS II

MHX — Monitor, Physiological, Patient(With Arrhythmia Detection Or Alarms)

What these counts are not

Clearance and recall counts are SPEQ’s aggregation of FDA’s own published records for the code. A recall count is a measure of history, not of a device’s safety, neither number is an FDA rating, and SPEQ is not affiliated with the FDA.

What this classification requires

Every statement below is FDA’s own classification record for this product code, quoted from the device classification field reference. The SPEQ reading beneath each one is SPEQ’s interpretation of what it means for the work, and is not FDA text.

PREMARKET PATHWAY

510(K)

SPEQ READINGA premarket notification under 21 CFR Part 807 Subpart E is the route for this code. The submission argues substantial equivalence to a legally marketed predicate, so the engineering question is which predicate the design can actually be compared against, and the evidence question is what testing supports that comparison.

DEVICE CLASS

Class II (moderate to high risk): general controls and special controls

SPEQ READINGSpecial controls are the distinguishing feature: performance standards, guidance documents, patient registries or postmarket surveillance named for the device type. Find the special controls before designing the test plan — they usually name the tests.

MALFUNCTION REPORTING

Device is eligible for The Voluntary Malfunction Summary Reporting Program

SPEQ READINGMalfunctions for this code may be reported in periodic summary form rather than as individual MDRs under 21 CFR Part 803. Eligibility is a property of the product code; using it is a decision the manufacturer makes and must be able to justify.

GMP / QUALITY SYSTEM

Not exempt due to Good Manufacturing Practice (GMP)/Quality System

SPEQ READINGThe full Quality Management System Regulation (21 CFR 820, incorporating ISO 13485:2016) applies, and is what an FDA inspection of this device will be conducted against.

IMPLANT

Device is not implantable

SPEQ READINGNo implant-specific expectations attach from the classification itself.

LIFE-SUSTAINING

Device is not used for life sustaining purposes

SPEQ READINGNo life-sustaining designation attaches to this code.

THIRD-PARTY REVIEW

Device is not a candidate for a third party review program

SPEQ READINGFDA reviews any premarket notification for this code directly.

Other product codes under 21 CFR 870.1025

One regulation usually governs several product codes. These share this code’s regulation, and therefore its classification basis.

21 CFR 870.1025 — Arrhythmia detector and alarm (including ST-segment measurement and alarm)

The classification regulation for this product code, as published by the Office of the Federal Register. This is the regulation text itself — no SPEQ interpretation appears in it.

(a) Identification. The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.

(b) Classification. Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document. [68 FR 61344, Oct. 28, 2003]
