prolongation that patients were taking stratified by drug class. Number
in the brackets denotes number of individual drugs. AAD =
anti-arrhythmic drugs; DPM = diphenhydramine; MCP = metoclopramide.
Figure 2 Bland Altman plots comparing mean QTc
intervals of the limb and chest leads. Horizontal line indicates mean
difference.
Figure 3 T-wave morphologies in each individual lead and
cumulative for limb and chest leads. Number In the brackets denotes
percentages.
Figure 4 12-lead ECG showing different T-wave morphologies over
individual leads in the same patient.
