NCT00354159
The purpose of this clinical research study is to evaluate the safety and effectiveness of the investigational implantable hemodynamic monitor (IHM), and of the IHM in combination with an implantable cardioverter defibrillator (ICD). The investigational IHM has the ability to record and report the force with which the heart pumps blood (heart pressures). When combined with the ICD, the device has the additional ability to send a strong electrical impulse, or shock, to the heart when it detects dangerously fast heartbeats to return it to a normal rhythm. The IHM and IHM/ICD are implanted surgically just under the skin in the upper chest area. This study will also determine how doctors use the information related to heart pressures in the management of heart failure.
