Biorepository of blood and or tissue samples from patients presenting with cardiac arrhythmia syndromes.
The long-term objective of this research is to find genes and biologic pathways causing arrhythmia syndromes and other diseases or conditions. In order to achieve this objective the investigators will collect comprehensive phenotypic data and corresponding blood and/or tissue samples into a biorepository registry of patients, presenting for cardiac arrhythmia evaluation and/or treatment, and control subjects without arrhythmias. This biorepository will be composed of two parts: 1) An Arrhythmia Biorepository of blood and tissue from patients undergoing arrhythmia procedures, cardiac surgery, or inpatient or outpatient evaluations for arrhythmias, and 2) A Collaborative Sample Biorepository for de-identified samples and data from outside institutions and clinical trials.
1,051 studies on the registry are indexed under Arrhythmias, Cardiac; 236 are open to participants now.
This study's planned enrollment of 2,000 is above the median of 200 across 467 observational studies indexed under Arrhythmias, Cardiac.
