CardioQ against SNUADC¶

Beats matched between the CardioQ's arterial pressure and SNUADC's put the CardioQ on the SNUADC timeline within each re-anchored stretch (matched-beat MAD 0.24 s).


Clock	CardioQ clock
Measured against	SNUADC sample clock
Modes	all
Status	measured
Correction size	0.4–4.4 s (p5–p95); matched-beat MAD 0.24 s (24 cases)

Correction¶

One offset per stretch between CardioQ re-anchors, from beat matching.

Evidence¶

Study	Date	Status	Summary
Rare devices against SNUADC	2026-10-13	current	CardioQ, EV1000, Vigileo and Vigilance each get a link to the SNUADC timeline: beat matching for the CardioQ, mean arterial pressure alignment for the EV1000 and Vigileo, and a long-window fit for Vigilance's averaged heart rate.
