[Ventricular arrhythmias and cardiac late potentials inpatients with acute coronary syndrome after reperfusion therapy].
The prognostic value of ventricular late potentials (VLP) and the character of rhythm disturbance were studied in 64 patients with acute coronary syndrome. 8 hours after system thrombolysis procedure VLP rate increased from 68.6% up to 85.7%. In all cases of reperfusion arrhythmia deterioration of signal-averaged ECG (SAECG) parameters and VLP were observed. Within the hospital treatment period VLP rate in the 1st group (patients receiving thrombolytic therapy) was lower than in the 2nd (no thrombolytic therapy). In the 1st group VLP was observed in 31.4% of the patients on the 10th day and in 11.4% by the end of hospital treatment; in the 2nd group--in 48.3% and 41.4% of the patients, respectively (p < 0.05). Administration of beta-adrenoblockers in both groups allowed improvement of SAECG parameters and cardiac rhythm variability.
