ABSTRACT:
Background: Single-chamber (VR-ICD) and subcutaneous (S-ICD) implantable cardioverter-defibrillators are effective to protect patients against sudden death but expose them to higher risk of inappropriate shock (IS). Auricchio A. et al. performed a meta-analysis of 16 studies to estimate the annual first IS rate among patients implanted with VR-ICD or S-ICD and determine the ISs influencing factors.In this article we refer to and shortly comment results of this meta-analysis. In the second part of this article, we focused on the comparison of single- and dual-chamber devices for IS rate. Conclusion: Using of dual-chamber ICDs increases the expense and peri-procedural complications without reducing inappropriate shocks or improving the quality of life.
