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 ECG findings of dextrocardia include a predominantly negative P wave (when sinus rhythm is present), negative QRS complex, and negative T wave in lead I. This results in a rightward QRS axis.

The ECG findings of dextrocardia include a predominantly negative P wave (when sinus rhythm is present), negative QRS complex, and negative T wave in lead I. This results in a rightward QRS axis.

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 ...
