When looking at a 12-lead ECG, a few logistics must be understood. First, the standard 12-lead ECG is a 10-second strip. The bottom one or two lines will be a full “rhythm strip” of a specific ...

The purpose of this study was to evaluate whether the 12-lead ECG could be substituted by ECG sets with a limited number of leads. Materials and methods: The performance of three ECG systems (ie ...

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 ...

One can either use calculated sums of the amplitudes of QRS complexes of all 12 leads ... that the use of the ECG along these lines in the care of patients with CHF will lead to further progress.
