Non-transvenous implantable cardioverter-defibrillator (ICD) therapy offers life-saving therapy without using intravascular leads. Recommended ICD generator placement is in the left mid- axilla between the latissimus dorsi muscle (LDM) and serratus anterior muscle (SAM) to optimize the defibrillation threshold and cosmetic outcomes.

In patients with implantable cardioverter defibrillator (ICD) inappropriate device therapy (IDT) is associated with worse outcomes and reduced quality of life (QoL). IDT is not rarely induced by misinterpretation of supraventricular tachycardia, detected by the ICD as atrial high rate episodes (AHRE).

Subcutaneous implantable cardioverter-defibrillators (S-ICDs) alleviate many issues associated with a transvenous system, while having similar efficacy to transvenous ICDs at preventing sudden cardiac death. However, S-ICDs have higher rates of shocks due to a lack of anti-tachycardia pacing (ATP).
