Abstract
The QT interval prolongation which happens during acute coronary syndrome is a dynamic parameter which changes at different points-reaches the peak point 24h after PCI and gets back in the normal range after 72h. QT dispersion follows this trend of change as well. Theres no difference of these changes between patients who present with STEMI, and patients with NSTEMI, except for the value of QT dispersion at admission which is shorter in the STEMI group. These patients have increased risk of malignant arrhythmias and should be closely monitored
