Implantable cardioverter-defibrillator. An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform cardioversion, defibrillation, and (in modern versions) pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias.
Prescription Treatments. Nail fungi are small organisms that require warm moisture to survive, which means that they thrive inside shoes and socks. This makes toe fungus especially difficult to treat. Prescription treatments include the oral medications terbinafine and itraconazole.
Essential Oils. Putting 2-3 drops of tea tree oil on your affected toenail can treat fungus infection effectively. Some other essential oils like eucalyptus oil, oregano oil, jojoba oil and primrose oils also contain antifungal and antiseptic properties that can fight fungus and heal the toenail effectively.
