Decompensation detection study (DECODE)

This study is for patients implanted with the Contak Renewal Family cardiac resynchronization therapy defibrillator and who have been prescribed the LATITUDE remote monitoring system.

The purpose of the study is to collect information from the remote monitoring system and from medical records to try to develop a way to predict when heart failure symptoms may occur. 

Participation in the study will be limited to a phone call from the study doctor or his or her staff every three months. Each call may last 5 to 15 minutes. Questions about recent heart failure events, any hospitalizations, emergency room visits or clinic visits will be asked. The study will last 2 years.

• Have been implanted with a Guidant Cardiac Resynchronization Therapy Defibrillator.

• Have rate-responsive pacing.
