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.
The best toenail fungus treatment over the counter may be an antifungal lacquer should an individual have a mild to moderate nail fungus infection. This is an antifungal nail polish also known as ciclopirox or pentac. Once a day, the polish is painted on the infected nail and surrounding skin.
