Summary

The purpose of this study is to define the safety of using bioimpedance for analysis of body composition in heart failure patients with ICD devices. The Biospace America InBody 520 scale, using direct segmental multifrequency bioimpedance, will be utilized to assess patients' fat mass, lean muscle mass, and edema status.

Although the Biospace America InBody 520 scale is routinely used to analyze body composition in various settings including the Ahmanson-UCLA Cardiomyopathy clinic, due to theoretical concerns of safety, bioimpedance has not been routinely used in patients with ICDs. The investigators hope that this study will allow us to routinely analyze body composition in heart failure patients with ICDs, information which can be used to help guide dietary, exercise, and medical prescriptions for the investigators heart failure patients.

Interventions

DEVICE

Body Composition Analysis InBody Scale

Patients will have their ICD interrogated using a pacemaker Programmer specifically designed from one of the 4 pacemaker manufacturers: St. Jude, Medtronic, Guidant, and Biotronik. Depending on the type of pacemaker, interrogation can be done either wirelessly or by placing a wand over the pacemaker. The ICD will be turned to a "monitor-only" mode to disable risk of ICD shock by the supervising electrophysiologist. Patient will be asked to step on the InBody 520 scale to have their body composition analyzed. Patient will continue to have their ICD actively monitored. Analysis will take approximately 30 - 50 seconds. At the end of analysis, ICD device will be returned to default settings by supervising electrophysiologist.
