Haldol is no longer recommended because the dyskinesia may persist even after the drug is stopped. I urge you to insist that your grandmother's Haldol be discontinued and that she be examined by a neurologist. Such a specialist will be able to determine whether her symptoms are caused by the Haldol or by some other condition, such as a primary nerve disorder. Also, the neurologist will be able to prescribe safer, more effective medicine to treat your grandmother's symptoms and her combative behavior. I'd certainly like to get rid of the many drugs I take for this affliction.
Cardiac pacemakers are electronic devices that trigger the heart to beat.
In simple terms, the typical pacemaker consists of a battery pack, somewhat smaller then a cigarette package, that is surgically implanted under the skin of the chest. The battery is connected to wires leading through the veins of the neck into the heart. A tiny computer next to the battery senses pauses in the pulse and instructs the battery when to fire a charge down the wires to stimulate a cardiac contraction. The computer is programmed to activate at a certain rate if the natural heartbeat slows or stops. Modern pacemakers are engineering marvels.
