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.
Apple Cider Vinegar. One of the best remedies for toenail fungus, apple cider vinegar can be used topically, internally, or both. Mix one part ACV and one part Epsom salts with six parts hot water. Let the water cool so that it is still warm to the touch, but not so hot as to be damaging to your skin.
