[Precordial ST segment elevation mapping: a new method for a technically easier recording (author's transl)].

Abstract

Precordial ST segment maps are currently recorded using a 35 electrode blanket connected to an electrocardiograph through a switch box. Problems in adjustment to patients' chests and artifacts are frequently encountered. Other techniques using a single suction electrode placed on different reference points are time wasting. The authors suggest the use of 35 self-adhesive electrodes (3M "Red Dot" chloride free gel pediatric electrodes--cat N. 2243) connected by a press button to a multichannel EKG recorder. This technique prevents artifacts, assures constant arrangement of the electrodes, is suitable for different thoracic structures and does not need any additional device. The authors consider that such a practical method should make precordial ST mapping a more widespread clinical procedure.
