This is a study of ICD patients receiving multiple therapies from defibrillators that seeks to find triggers for such events and identification of markers that may aid in guiding therapy.

Arrhythmias |
Procedure: Peripheral blood sampling |
Study Type: | Observational |
Study Design: | Cohort, Prospective |
Official Title: | Gene Expression in ICD Patients With Electrical Storm |
2 RNA samples are obtained and kept frozen on-site to be evalauted at a later date. A portion of this DNA will be used to analyze the structure of certain genes that are known to play a role in cardiac arrhythmias. We cannot at this time know exatly what genes will be tested.
Estimated Enrollment: | 30 |

This is a study of patients with ICD implants who present with multiple shocks, termed electrical storm. The purpose of this pilot study is to identify factors which are associated with periods of high ventricular arrhythmia burden by looking at gene expression from peripheral blood, in addition to levels of known markers of CHF, including catecholamine levels, B-type natriuretic peptide, and troponin. This study hypothesizes that extrinsic or systemic factors play a role in triggering these events, and if true should yield candidate proteins which would spawn functional studies to prove a role in causation. Additionally, identification of a marker of increased recurrence of events may aid in guiding therapy (starting an anti-arrhythmic versus awaiting the next event).
