In addition to changes in the ECG caused by disease, there are a variety of atypical ECG patterns, often called 'normal variants ... syndromes should lead to improved understanding of underlying ...

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 ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed or (2) ‘abnormal’—further evaluation needed. Normal ECGs include common, ...

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 ...
