Positive and negative peaked T waves with high amplitude were detectable in the preclinical 12-lead ECG. Additionally, a first-degree AV block was present (P waves merging with preceding T waves).

As noted above, the precordial leads are unreliable, compromising by their inclusion calculations deriving from the set of 12 ECG leads. It appears, therefore, that using sums of data from the six ...
