Narrow QRS HF Patients Assessed by ECG Belt

Electrical Dyssynchrony in Narrow QRS Heart Failure Patients as Assessed by the ECG Belt

The purpose of this study is to quantitate electrical dyssynchrony in heart failure (HF) patients with a narrow QRS complexes (≤ 130 ms) using the ECG Belt. This is a pilot study that is designed to provide data that can be used in designing and implementing a prospective study of cardiac resynchronization therapy (CRT) in narrow QRS patients selected and optimized using the ECG Belt.
