Figure 1. 12-lead ECG readings identified
Of the 148 patients with 12-lead ECG readings we reviewed, 48 patients had neither a custom alert nor a DDI warning. One hundred patients represented a total of 521 custom alerts and 449 DDI warnings, including those which actually triggered and those which were filtered (Figure 2). Eighty out of the 100 patients had both a custom alert and DDI warning trigger, but none of the patients had a DDI warning exclusively without a custom alert.
