The adaptive CRT (aCRT) is an innovative algorithm that was developed to avoid unnecessary right ventricular (RV) pacing through continuous intracardiac delay evaluation. We present a case of unexpected wide QRS paced rhythm after successful implantation of CRT in patients with right bundle branch block (RBBB) and describe the reasons and the programming changes required to resolve it.
适应性 CRT（aCRT）是一种创新算法，旨在通过持续的室内延迟评估避免不必要的右心室（RV）起搏。我们介绍了一例右束支传导阻滞（RBBB）患者成功植入 CRT 后出现意外宽 QRS 起搏节律的病例，并描述了导致该节律的原因和需要进行的程控改变。
