Paper Abstract

Results of routinely used frank leads do not relate to localization of the point of origin of late potentials (LP). In 13 pts. with anterior myocardial infarction (AMI) 12 with posterior rnyocardial infarction (PMI) und 6 with arrhythrnogenic right ventricular dysplasia (ARVD) high amplified signal averaged mapping with at least 16 leads has been performed. The maxima for LP duration voltage and calculated indica tors Ri and R2 are relatively homogeneously localized between left parasternal (PSL) and rnedioclavicular (MCL) line and the 4. - 6 rib. In PMI the maxima are less homogeneous but in the same area and in ARVD to the right of sagittal line. The maxima correlate to localiza tion of kinetc disturbances in MI. This technique does not provide exact localization of LP origin but helps planning endornap and has higher accuracy for risk prediction.
