The authors present two cases of patients with perforation of the right ventricular wall by the implantable cardioverter defibrillator (ICD) lead. The complication was resolved by cardiosurgical revision and epicardial leads stitched onto the diaphragmatic wall of the heart. The perforation was identified by electrical parameter changes of the leads,(More)
A circadian distribution has been demonstrated in episodes of sudden cardiac death, acute myocardial infarction, ventricular premature complexes, heart rate variability, and ventricular tachyarrhythmias. The aim of this study was to evaluate the circadian distribution of ventricular tachyarrhythmia episodes in a population of ICD patients. Data were(More)
BACKGROUND Observations from population-based studies demonstrated a strong genetic component of sudden cardiac death. The aim of this study was to test the hypothesis that ion channel genes mutations are more common in ventricular fibrillation (VF) survivors with coronary artery disease (CAD) compared to controls. METHODS The entire coding sequence of(More)
The aim of this study was a comparison of risk stratification for death in patients after myocardial infarction (MI) and of risk stratification for malignant arrhythmias in patients with implantable cardioverter-defibrillator (ICD). The individual risk factors and more complex approaches were used, which take into account that a borderline between a risky(More)
BACKGROUND A common ICD therapy-related complication is arrhythmic storm (AS). The objective of our study was to define the impact of AS on patients' prognoses in order to compare the total mortality of AS patients with the rest of the group. MATERIAL/METHODS We studied 138 patients who received ICDs between 1994 and 2001. Patients who experienced one or(More)
BACKGROUND Some study reported circadian occurence of sudden cardiac death, ventricle ectopic activity, acute coronary syndromes and heart rate variability. Heart rate turbulence (HRT) is one of a new markers of noninvasive stratification of sudden cardiac death. METHODS AND RESULTS We have evaluated HRT in 120 consecutive patiens post myocardial(More)
BACKGROUND Using implantable cardioverter-defibrillators in treatment of malignant ventricular arrhythmias revealed new complications specific to this therapy. Inappropriate therapy, arrhythmic storm and device related proarrhythmia belong to the most significant complications. The authors describe specific complications in a group of ICD patients, analyze(More)
BACKGROUND Syncope state performed by transient loss of consciousness connected with a postural tone decrease present still an important therapeutical problem. The authors use HUT testing for discovering of vasovagal etiology of a syncope. The aim of the study was to find out the optimal medication in treatment and prevention of VVS by repeated HUT drug(More)
Implantable cardioverter defibrillators have become an integral part of treatment of patients with malignant chamber arrhythmias over last 10 years both in secondary and primary prevention of sudden deaths. Based on monitoring of a group of 182 patients and based on information in literature, authors present a survey of the most frequent situations, rules(More)
Syncope, a state performed by transient loss of consciousness connected with postural tone decrease present still an important therapeutical problem. It can vary from a benign physiological body reaction to a life-limiting situation. The authors of the article present HUT-testing to be a simple, useful and safe method for discovering vasovagal mechanism of(More)
