Comparison Study of BNP and Thoracic Impedance Measurements on Arrhythmias
Withdrawn before enrolling
Conditions studied: Heart Failure, Arrhythmias
In brief
It is hypothesized that elevated BNP level correlate with an elevated thoracic impedance/fluid index as measured separately by CRT-D devices and external impedance cardiography. Ultimately, it is also hypothesized that both BNP and thoracic impedance/fluid index measurements are predictive of atrial and ventricular arrhythmias.
