Interventricular conduction delay predicts CRT response: a comparative evaluation study between biventricular pacing and conduction system pacing | Synapse
March 9, 2026Journal of Interventional Cardiac Electrophysiology0 citations
To evaluate how interventricular conduction delay can predict the response to cardiac resynchronization therapy (CRT) between two pacing methods.
Conducted a comparative evaluation of biventricular pacing and conduction system pacing.
Analyzed patients with heart failure and interventricular conduction delay.
Used response metrics such as improvement in ejection fraction.
Patients with interventricular conduction delay showed a significant increase in CRT response rate with conduction system pacing compared to biventricular pacing.
Biventricular pacing yielded a response rate of 60%, while conduction system pacing resulted in an 80% response rate, highlighting a difference in effectiveness.
