Correlation Of Respiratory Rate Level And Trend Evaluation in Heart Failure Patients

Terminated

• Conditions: Heart Failure
• Interventions: Device: Cardiac Resynchronization Therapy Defibrillator

• Registration Number: NCT00758121
• Lead Sponsor: Boston Scientific Corporation

Brief Summary

The objective of the study is to determine if there is any relationship between respiratory rate and Heart Failure events.

Detailed Description

The purpose of the CORRELATE-HF study is to collect RRT data in heart failure patients to gain a better understanding of how respiratory rate changes in relation to all cause clinical events as well as other diagnostic features, including but not limited to, activity level, heart rate, and lead impedance.
