Bradyarrhythmia | Identify the Genes Polymorphisms Related to Non-familial Bradyarrhythmia
Bradyarrhythmia research study
What is the primary objective of this study?
Bradyarrhythmia, including sinus node dysfunction and atrioventricular block, is a major cause necessitating pacemaker implantation. In contrast to familial bradyarrhythmia known as by mutations at particular ion channels, limited information is available for the mechanistic study in non-familial bradyarrhythmia. Possible gene polymorphisms related to non-familial bradyarrhythmia were studied. Comparison of multi-locus analysis and single-locus analysis will be analyzed between the cases and controls. Functional studies will perform to clarify the results of association study.
Who is eligible to participate?
Inclusion Criteria: - The patients with non-familial bradyarrhythmia Exclusion Criteria: - Familial bradyarrhythmia Reversible bradyarrhythmia Bradyarrhythmia after open heart surgery and severe organic heart diseases
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
