A defibrillator is similar to a pacemaker, but can do much more. All defibrillators have a pacemaker function. In addition, if there is an electrical short circuit or ventricular arrhythmia, the defibrillator will shock the heart back to normal rhythm. Like a pacemaker, the larger generator sits under the skin. Wires from the generator go to the heart to provide electrical impulses to pace or shock the heart. There are many types of defibrillators, single lead, dual lead and three lead (CRT) devices.
Monitoring the device and setting up optimal parameters is the goal at CHC.
