title: [Predictors of life-threatening arrhythmias in patients with implanted cardioverters-defibrillators].
abstract: To determine and analyze factors influencing onset of life-threatening cardiac arrhythmia in patients with implanted cardioverters-defibrillators (CD), 149 patients were examined by 70 characteristics including results of medical examination prior to implantation of CD, data of regular postoperative outpatient control. It was found that onset and discharge frequency of CD depended much on cardiac failure of NYHA functional class III-IV (p = 0.0423), induced ventricular tachycardia in electrophysiological test (p = 0.029), myocardial infarction (MI) without operative revascularization (p = 0.042) or 2 and more MIs irrespective of revascularization (p = 0.002), supraventricular tachycardia (p = 0.041). Groups of high risk to develop life-threatening arrhythmia among patients with implanted CD were selected. The results of the investigation can be used for the design of recommendations how to reduce the probability of ventricular tachyarrhythmia and how to lessen the frequency of CD operation and raise quality of life for patients with implanted CD. Moreover, the findings can be used for specifying indications for CD implantation.
