Measuring Activated Clotting Time during Cardiac Catheterization and PCI: The Effect of the Sampling Site

Figure 2

Bland–Altman plots of three ACT sample site comparisons. ACT = activated clotting time; AS = arterial sheath; GC = guiding catheter; IVL = peripheral intravenous line; MD = mean difference; and SD = standard deviation. Systematic differences in ACT between the (a) guiding catheter and arterial sheath, (b) guiding catheter and intravenous line, and (c) arterial sheath and intravenous line.
