K922394 is an FDA 510(k) clearance for the CARDIOFAX Q ECG-8420A.

Submitted by Nihon Kohden America, Inc. (Irvine, US). The FDA issued a Cleared decision on March 1, 1994 after a review of 650 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Cardiovascular submissions.
