摘要

目前的指南建议制定心律转复除颤器（ICD）规划，包括更快的检出率、更长的检测持续时间和严格区分室上性心动过速（SVT），以防止不必要的ICD治疗。这种延迟式ICD编程可能导致VF感知不足的可能性增加。为了避免这种风险，一种创新的算法被称为VF治疗保证(VFTA；雅培，Sylmar， CA)已经开发。在近场r波信号感应不足的情况下，VFTA在VT或VF发作时使用远场r波信号提供ICD治疗。

Utility of using far-field R-wave signals in the detection of fatal ventricular arrhythmia

Current guidelines recommend cardioverter-defibrillator (ICD) programming, including faster detection rates, longer detection durations, and strict discrimination for supraventricular tachycardia (SVT) to prevent unnecessary ICD treatment. This delayed-style ICD programming could lead to a rise in the possibility of VF undersensing. To avoid this risk, an innovative algorithm known as VF Therapy Assurance (VFTA; Abbott, Sylmar, CA) has been developed. VFTA uses far-field R-wave signals during VT or VF episodes to provide ICD therapy in cases of near-field R-wave signal undersensing.
