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 QTc-intervals in different ECG leads were measured. In about 30% of pts with AMI there were prolonged (greater than or equal to 440 ms) QTc-values. Patients with AMI suffering from VT or non-survivors had the longest QTc-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 QTc in patients with cerebral tumours are not correlated with prognosis but with the severity of neurological disturbances.
