Heart Failure Intrathoracic Impedance Monitoring, Audible Patient Alerts, and Outcome in Patients With Heart Failure
Background—Heart failure is associated with frequent hospitalizations, often resulting from volume overload. Measurement of intrathoracic impedance with an implanted device with an audible patient alert may detect increases in pulmonary fluid retention early. We hypothesized that early intervention could prevent hospitalizations and affect outcome. Methods and Results—We studied 335 patients wi...
متن کاملContinuous monitoring of intrathoracic impedance and right ventricular pressures in patients with heart failure.
BACKGROUND Hemodynamic monitoring using implantable devices may provide early warning of volume overload in patients with heart failure (HF). This study was designed to prospectively compare information from intrathoracic impedance monitoring and continuous right ventricular pressure measurements in patients with HF. METHODS AND RESULTS Sixteen patients with HF (age, 63.5+/-13.8 years; left v...

متن کاملIntrathoracic impedance monitoring in patients with heart failure: correlation with fluid status and feasibility of early warning preceding hospitalization.
BACKGROUND Patients with heart failure are frequently hospitalized for fluid overload. A reliable method for chronic monitoring of fluid status is therefore desirable. We evaluated an implantable system capable of measuring intrathoracic impedance to identify potential fluid overload before heart failure hospitalization and to determine the correlation between intrathoracic impedance and standa...
