Vectorcardiograms obtained with the Frank system were obtained in 12 male subjects with classic electrocardiographic criteria of WPW. The direction of the delta force was anteriorly directed in all, with the greatest percentage (58 per cent) lying from 0 to 90 degrees in the frontal plane. In one subject a comparison of the pre- and postmyocardial infarction QRS-loop reveals an unaltered delta force following the infarction. The forces after the delta wave have the characteristic superior direction of a posterior wall myocardial infarction. This observation may be of aid in detecting myocardial infarction in subjects with WPW.
