PROGNOSTIC-SIGNIFICANCE OF DIFFERENT QT-INTERVALS IN THE BODY-SURFACE ECG IN PATIENTS WITH ACUTE MYOCARDIAL-INFARCTION AND IN PATIENTS WITH ACUTE OR CHRONIC CEREBRAL PROCESSES

In 73 patients after AMI, 131 patients with cerebral stroke and in 116 patients with cerebral tumours the QT(c)-intervals in different ECG leads were measured. In about 30% of pts with AMI there were prolonged (greater-than-or-equal-to 440 ms) QT(c)-values. Patients with AMI suffering from VT or non-survivors had the longest QT(c)-values. Also in patients with cerebral stroke and prolonged QT-values (greater-than-or-equal-to 440 ms) the risk of dying was significantly higher than in patients that survived. The prolongation of QT(c) in patients with cerebral tumours are not correlated with prognosis but with the severity of neurological disturbances.
