The SonR signal has been shown to reflect cardiac contractility. It is recorded with an atrial lead connected to a cardiac resynchronization therapy defibrillator. For the first time, clinical evidence on the use of the SonR signal in the monitoring of the clinical status of heart failure patients implanted with cardiac resynchronization therapy defibrillator are presented through three clinical cases.
In the two first patients (non-Hispanic/Latino white), the SonR amplitude increases concomitantly to clinical status improvement subsequent to cardiac resynchronization therapy defibrillator implantation. In the third patient (non-Hispanic/Latino white), a decrease in SonR amplitude is observed concomitantly to atrial fibrillation and clinical status deterioration.
This case series reports the association between SonR signal amplitude changes and patients' clinical status. Combined with remote monitoring, early SonR signal amplitude remote monitoring could be a promising tool for heart failure patients' management.
SonR信号已被证明可反映心脏收缩力。它通过连接到心脏再同步治疗除颤器的心房导联进行记录。本文首次通过三个临床病例展示了关于使用SonR信号监测植入心脏再同步治疗除颤器的心力衰竭患者临床状态的临床证据。
在前两名患者（非西班牙裔/拉丁裔白人）中，心脏再同步治疗除颤器植入后，随着临床状态改善，SonR振幅相应增加。在第三名患者（非西班牙裔/拉丁裔白人）中，观察到SonR振幅下降，同时伴有心房颤动和临床状态恶化。
本病例系列报告了SonR信号振幅变化与患者临床状态之间的关联。结合远程监测，早期SonR信号振幅远程监测可能成为心力衰竭患者管理的一种有前景的工具。
