Why the study?
Do impedance sensors in implantable defibrillators improve disease monitoring and therapy adaptation in heart failure patients?
Do impedance sensors in implantable defibrillators improve disease monitoring and therapy adaptation in heart failure patients?
Impedance sensors in implantable defibrillators offer a promising approach for monitoring lung fluid status and cardiac hemodynamics in heart failure patients.
May support remote HF monitoring; Level 5 review leaves open need for outcome trials before adoption.
Heart failure is one of the most frequent diseases and a leading cause for hospital admission and death in Germany and other industrialized countries. Two types of impedance sensors are presented that promise to allow improved disease monitoring and hence better therapy adaptation in heart failure patients with an implanted defibrillator: thoracic impedance to estimate the lung fluid status of the patient, and intracardiac impedance for assessment of cardiac hemodynamics.
