Interventricular conduction delay predicts CRT response: a comparative evaluation study between biventricular pacing and conduction system pacing

Key Points

• 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.
