First-shock S-ICD efficacy may be suboptimal; leaves open need for prospective optimization in sudden-death prevention.
Does the subcutaneous ICD effectively detect and convert ventricular tachyarrhythmias in patients requiring primary or secondary prevention of sudden cardiac death?
While overall shock efficacy of the S-ICD is high, first-shock efficacy may be suboptimal, highlighting the need for careful patient selection and monitoring.
Sill et al. (2013) studied this question.
