Biventricular pacing (BIV) is the standard treatment for cardiac resynchronization therapy (CRT), but 30% of patients do not respond; conduction system pacing (CSP) is an alternative worth exploring.
A study involving 96 patients compared outcomes based on intraoperative measurements of interventricular conduction delay (IVCD) to determine whether BIV or CSP would be more effective.
Results showed that patients in the group evaluated for IVCD had significantly higher response rates to CRT, suggesting that this assessment can inform better treatment choices.
