BACKGROUND AND PURPOSE Some de- and re-polarization patterns can reflect an increased risk of ventricular tachyarrhythmias. We studied whether some electrocardiographic (ECG) patterns are able to predict the development of ventricular fibrillation (VF) during acute myocardial infarction (MI). METHODS We compared the patterns of ST-T segment of 78 patients(More)
BACKGROUND The prognostic value of chronic inflammation markers in patients after myocardial infarction (MI) in the era of interventional treatment, statin and aspirin use is still unclear. METHODS The study was carried out on 107 patients with a first MI who were followed up for 18 months. The end points were cardiac death, reinfarction or unstable(More)
We describe 2 patients with arrhythmogenic right ventricular cardiomyopathy (ARVD): 58 year-old female and 48 year-old man. Both patients presented with echocardiographic features typical for ARVD and impaired systolic left ventricular function. Both patients had symptoms resembling acute coronary syndrome and received cardioverter-defibrillator due to(More)
AIMS Periodic breathing with central sleep apnoea (CSA) is common in heart failure patients and is associated with poor quality of life and increased risk of morbidity and mortality. We conducted a prospective, non-randomized, acute study to determine the feasibility of using unilateral transvenous phrenic nerve stimulation for the treatment of CSA in heart(More)
AIMS To investigate the effect of implantation-related characteristics, especially lead position and left ventricular (LV)-paced QRS morphology, on long-term mortality and morbidity in cardiac resynchronization therapy (CRT) patients. METHODS AND RESULTS The study retrospectively analysed 362 consecutive patients who underwent CRT device implantation over(More)
Sudden cardiac death (SCD) is responsible for almost 50% of all cardiac deaths in the U.S. The most common underlying cause of SCD is coronary artery disease, especially acute myocardial infarction (AMI). There are no publications concerning the shape of ST segment elevation in AMI and the risk of ventricular fibrilation (VF) or SCD. We present three cases(More)
AIMS To compare the sensitivity (SN), specificity (SP), and diagnostic accuracy (ACC) for ventricular tachycardia (VT) diagnosis of five electrocardiographic methods for wide QRS-complex tachycardia (WCT) differentiation, specifically the Brugada, Bayesian, Griffith, and aVR algorithms, and the lead II R-wave-peak-time (RWPT) criterion.
