Advantages, limitations and new perspectives on the implantation of subcutaneous cardioverter-defibrillator

Abstract

Subcutaneous cardioveter-defibrillator (S-ICD) gained considerable place in sudden cardiac death (SCD) preven - tion. The main advantage of this device is the possiblility of implantating it outside of blood vessel. The lack of permanent pacing and antitachycardia pacing (ATP) are its key limitations. New research is focused on creating an extravessel device that could combine the role of cardioverter and pacemaker. The main difficulty is the mutual interference of sensing
