New Electrocardiographic Leads and Regional Vectorcardiograms

pp. 359-366

Abstract

Precordial bipolar leads (PBL) provide new information from the standard 12-lead ECG. These leads are an ideal complement to the traditional unipolar leads (V1 to V6) of the ECG because they are practically perpendicular to the latter and allow evaluation of the right-to-left and anteroposterior precordial axes, as well as the construction of regional vectorcardiograms (RVCG) that enable the selection of the specific myocardial region to be studied without interference from other parts of the heart.
An important advantage is that, using the appropriate software, it is possible to simultaneously generate the standard ECG and VCG as well as the new leads and RVCG. All this information can be derived from data stored in a hospital database, provided they have been digitally recorded by a simultaneous 12-channel ECG. This means that no additional electrodes or cables and no extra technical work are required.
Using typical ECG data, various bipolar leads, weighted unipolar leads, RVCG and ECG circular charts can be created. These new displays have made it possible to identify previously undetected abnormal electrophysiological patterns.
