New ECG Methods: A Study Based On Precordial Bipolar Leads

Several new methods of electrocardiographic exploration are presented in this work. All are based on processing the information already obtained when a standard 12-channel ECG is performed. They need no additional electrodes or cables.ECG is performed in the usual way producing the classic 12 tracings. However, using the data already collected, bipolar precordial leads, polar coordinates, sub derivations and new weighted derivations can be obtained.The new methods allow seeing clearly some phenomena difficult to appreciate in the routine tracings of the 12-channel ECG.
