What distinguishes the wearable cardioverter defibrillator from an ICD?

Answer

It is worn externally like a vest rather than being surgically implanted

The wearable cardioverter defibrillator is a specialized medical device prescribed to patients at risk of sudden cardiac arrest who are not immediate candidates for an implantable cardioverter defibrillator or are currently waiting for one. The key distinction is its non-invasive nature; it is worn externally as a garment, similar to a vest. This device continuously monitors the patient heart rhythm on a 24/7 basis, automatically detecting dangerous arrhythmias and delivering a life-saving treatment shock if necessary, all without the need for surgical implantation.
