K903644 is an FDA 510(k) clearance for the SERIES 1500 12-LEAD ANALYSIS OPTION.
Submitted by Marquette Electronics, Inc. (Milwaukee, US). The FDA issued a Cleared decision on December 27, 1991 after a review of 501 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.
