China Structural Ventricular Arrhythmias Registry
China Structural Ventricular Arrhythmias Registry
This is an observational, prospective, multi-center registry ,aiming at building a risk
 stratification for malignant structural ventricular arrhythmias. 2000 participants will be
 recruited from 10 centers in China,with clinical data to be abstracted from medical records
 ,and blood samples to be collected for finding promising risk indicators.The follow-up should
 be made every 6 mouths.
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.
Inclusion Criteria:

 -  diagnosed as ventricular arrhythmia resulted by structural heart diseases, including
 ischemic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, dilated
 cardiomyopathy, hypertrophic cardiomyopathy, etc.

 Exclusion Criteria:

 -  none
