[Management of ventricular tachycardia after acute myocardial infarct].

Background: Risk stratification of malignant ventricular tachyarrhythmias and sudden cardiac death after myocardial infarction is essentially important for high risk patients identification, who require specific therapeutic procedures. Non-invasive risk markers--LVEF, late potentials LP, Q-T dispersion, decreased heart rate variability (HRV) and baroreflex sensitivity (BRS)--and ventricular tachycardia inducibility have low positive predictive value. The appropriate combination and consecutiveness which will provide most precise identification of patients threatened by sudden arrhythmic death, applicable to all patients after myocardial infarction, is being analysed.

[Risk factors and prevention of sudden cardiac death in patients with ventricular tachycardia after myocardial infarct].

Unlabelled: The optimal therapeutic procedure for prevention of sudden cardiac death (SCD) after myocardial infarction involves identification of the patients with a high risk of malignant ventricular arrhythmias using non-invasive risk markers, invasive electrophysiological evaluation of high risk patients, selection of treatment (ICD, RFTA, antiarrhythmics) and evaluation of the effectiveness of treatment. The objective of this work is retrospective evaluation of the incidence of risk markers of sudden cardiac death and the importance of programmed ventricular stimulation for the prognosis of patients with malignant ventricular arrhythmias after myocardial infarction.

[Treatment of paroxysmal ventricular tachycardia].

The authors present a retrospective evaluation of the risk stratification and therapy of 53 patients with ventricular tachycardia. They present the diagnostical algorithm used for the detection of risk of sudden death. The most frequently used drug in the set of patients was amiodarone in monotherapy or in combination with other drugs.

[Dispersion of the Q-T interval after myocardial infarct].

Non-homogenity of ventricular myocardial repolarization is a substrate for the reentry mechanism of ventricular arrhythmias. It is manifestant by dispersion of Q-T and Q-Tc intervals on the standard ECG curve. The authors studied the possibility of using the dispersity of Q-T and Q-Tc intervals in clinical practice.

[Autonomic nervous system tests in the classification of patients at risk for sudden cardiac death].

The authors present an insight into the role of the nervous system in relation to the risk of sudden cardiac death. They present the basic diagnostic possibilities provided by examination of the autonomous nervous system, namely heart rate variability and baroreflex sensitivity. Reduced heart rate variability and the depression of baroreflex sensitivity represent independent risk markers of sudden heart death.
