Table 2. Intrathoracic impedance in management of individuals with heart failure.

Intrathoracic impedance as an index of lung fluids	Modest correlation with estimated pulmonary diastolic arterial pressure
Comparison of intrathoracic impedance versus body weight	Intrathoracic impedance more sensitive than body weight
Prognostic value of intrathoracic impedance	Modest sensitivity and modest positive predictive value
Value of remote intrathoracic impedance monitoring	Good correlation in individuals with heart failure and chronic kidney disease
