Zusammenfassung

Das Elektrokardiogramm (EKG) ist eine zweidimensionale Dokumentation von Potentialschwankungen des Herzens als Funktion der Zeit. Zur Klärung klinisch-diagnostischer Fragen werden diese Potentialschwankungen über folgende Ableitungen von der Körperoberfläche aufgezeichnet: 3 bipolare Extremitätenableitungen nach Einthoven (I, II, III), 3 unipolare Extremitätenableitungen nach Goldberger (aVR, aVL, aVF) und 6 unipolare Brustwandableitungen nach Wilson (V1–6). Für spezielle Fragestellungen haben sich zusätzlich die dorsolateralen, unipolaren Brustwandableitungen (V7–9) als erweitertes Wilson-Programm sowie die bipolaren Ableitungen nach Nehb (D, A, I) und auch die 3 korrigierten orthogonalen Ableitungen nach Frank (X, Y, Z) bewährt (Heinecker u. Gonska 1992; Lichtlen 1969; Pipberger et al. 1975; Schaub 1965). Für die Registrierung des EKG sind Papiervorschübe von 25 und 50 mm/s Standard geworden. Um jeweils mehrere Herzzyklen über die genannten 12–15 Standardableitungen aufzeichnen zu können, werden in der Regel Zeiten zwischen 30 s und 2 min benötigt. Dieser Zeitbedarf für die Aufzeichnung des Standard-EKG unter Ruhebedingungen entspricht der vielfältigen Erfahrung in Klinik und Praxis.
