Zusammenfassung
Verspätete ventrikuläre Depolarisationen im hochauflösenden EKG werden durch die visuelle oder automatische (11, 17) Beurteilung der zeitlichen Änderung ihrer Spannungsamplitude ermittelt. In neuerer Zeit wurde von Vorteilen der Frequenzanalyse verspäteter Depolarisationen mit der Fast-Fourier-Transformation (FFT) berichtet (2, 3).
