[The relationship between increased QT dispersion of acute myocardial infarction and ventricular fibrillation].
We measured 62 patients' QT dispersion (QTd) and JT dispersion (JTd) of acute myocardial infarction (AMT) on first ECG within 48 hour. The results showed that QTd and JTd were greater in 16 patients with ventricular fibrillation (Vf) compared without Vf (QTd mean 107.50 +/- 35.80ms to 48.90 +/- 17.90 ms, P < 0.01; JTd mean 107.50 +/- 31.00ms to 52.60 +/- 19.00 ms, P < 0.01) during the early phase of AMI. That long QTd and/or JTd may possibly relate to Vf of AMI. Thus, we suggest that QTd and/or JTd may be of significant prediction value for prognosis of AMI.
