BradyarrhythmiaNCT01310907
Identify the Genes Polymorphisms Related to Non-familial Bradyarrhythmia
An observational study of Bradyarrhythmia, run by China Medical University Hospital at 2 sites in Taiwan.
Trial summary
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.

About 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.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 9 Mar 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jan-Yow Chen, MD (+422052121 ext. 2311, janyow@ms77.hinet.net), or a site near the patient. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01310907, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2011.
