[Regional differences in frequency-corrected QT duration in multi-electrode ECG in ventricular extrasystole].
Issuing from the pathophysiological significance of a prolongation of the QT-time for the diagnostics and therapy of ventricular arrhythmias examinations on 15 patients with ventricular extrasystoles by means of multi-electrode-ECG are demonstrated in comparison to 10 test persons with healthy heart. 2 regions on the thoracic surface with significant prolongation of the QT-time in the group of patients are described: Regio hypochondriaca parasternally left and left posterior axillary line at the level of the 7th and 8th thoracic vertebral body.
