In China, the prevalence and risk factors of malignant ventricular arrhythmias remain unclear. In addition ,the mainstream treatment relies on implantable devices and medication.China Malignant Ventricular Arrhythmias Study is a nation-wide complex consisting of several interrelated studies, with the aim of building a risk stratification as well as a efficient and economic strategy for early prevention and treatment.
Structural Ventricular Arrhythmias Registry, as a part of China Malignant Ventricular Arrhythmias Study, is an observational, prospective, multi-center registry, aiming at building a risk stratification for malignant structural ventricular arrhythmias. 2000 patients with definitive diagnosis will be recruited consecutively from 10 major arrhythmia centers distributed in 6 areas in China. At study entry, participants will be interviewed and asked to sign the informed consent. Demographic characteristics, medical history, clinical features, laboratory tests, imaging pictures, medications, procedures, and in-hospital outcomes of patients will be abstracted from medical records by well trained staffs .At the same time, blood samples will be collected to detect biological markers, like genes, inflammatory factors ,etc. Once enrolled, the participants will receive follow up every 6 mouths about condition of arrhythmia, medication, clinical events, etc.
