Summary Ventricular tachyarrhythmias - a retrospective analysis of etiology, demography and treatment Ugeskr Læger 2008;170(25):2234-2237 Introduction: The aim of this study was to investigate the age, sex, etiology, frequency of implantable cardioverter-defibrillator (ICD) and previous cardiac arrest among patients discharged from the Department of Cardiology, Rigshospitalet (Copenhagen University Hospital), Denmark due to ventricular tachyarrhythmias. Materials and methods: We conducted a retrospective review of 993 patients discharged from Rigshospitalet over 6 years and 5 months with the diagnostic codes ventricular tachycardia, ventricular fibrillation or premature ventricular contractions. Results: The population had an average age of 59 years (ranging 15-95 years) with a majority of males (76%). Among the patients with known etiology ischemic heart disease (60%), dilated cardiomyopathy (6%) and arrhythmogenic right ventricular cardiomyopathy (6%) were the most frequent. A substantial number of the patients (15%) had unknown etiology; 492 (50%) of the patients overall had an ICD implanted, the majority of whom had been categorized as having ventricular tachycardia (92%); 168 patients had previous cardiac arrest, 127 of whom did not have a potential reversible cause. Of this group 75 (59%) had an ICD implanted. Conclusion: Ischemic heart disease is the most common cause of ventricular tachyarrhythmias. Approximately half the patients admitted with ventricular tachyarrhythmias had an ICD implanted, the majority of whom did not have previous cardiac arrest.
