Abstract

SummaryThe author investigates the signification of the Cabrera and Friedland’s sign in the general matter of left intra-ventricular conduction disturbances associated with a myocardial infarction, this one being antero-lateral or anterior as well as antero-septal.This sign is constituted by a slurring of 0,05 sec. or more, surcharging the reascending branch of the S wave in the precordial derivations with a rS, or QS complex. Its incidence is 91 % in the cases considered by Cabrera and Friedland (left complete bundle branch block associated with antero-septal infarction). In opposite, its incidence is only 9 to 13,6 % in the more extensive frame considered by the author.Furthermore, its value, given as pathognomonic by Cabrera and Friedland, becomes here a sign of presomption.The author investigates in the same work the signification of the terminal slurrings he met in the cases of left intra-ventricular conduction disturbances associated with an anterior infarction. If the documents examined do not perm...
