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 ...
or at least 250 QRS complexes in order to see minute changes in the electrical activity that is not apparent on the standard 12-lead ECG. “Early afterdepolarizations” or “late potentials ...
