Response to Cardiac Resynchronization Therapy of Previously Right Ventricular Paced Heart Failure Patients

Completed

Conditions studied: Heart Failure, Pacing Induced Dyssynchrony

In brief

The present proposal is designed to investigate the response to CRT in patients who were previously paced from the right ventricle (RV). The negative physiologic and structural changes associated with chronic RV pacing are well documented, but patient response following upgrade to CRT after chronic RV pacing has not been well characterized in a large cohort.
