cardioversion is delivering an electrical shock to a person's heart to rapidly restore an abnormal heart rhythm back to normal, two types of cardioversion, external, internal, external cardioversion, an external cardioversion, performed in an emergency situation, a person's heart is beating abnormally, inadequately pumping blood, an electrical shock is given, a defibrillator to revert the heart rate to a normal rhythm, times, an external cardioversion is scheduled ahead of time to treat an arrhythmia, most often atrial fibrillation, recent, has not responded well to medication, scheduled cardioversion, necessary to run tests to make sure, no blood clots, in the heart, need medication to "thin" blood, having the cardioversion, scheduled cardioversion, person, sedated beforehand, breathing is assisted, doctor then delivers an electrical shock, a defibrillator, heart using paddles on the patient's chest, electrical shock, makes the person's heart convert back to a normal rhythm, afterwards, to decrease the likelihood, the arrhythmia returning, prevent blood clots from entering the general circulation, the doctor, recommend a medication regimen, internal cardioversion, an internal cardioversion is delivered by a device similar to a pacemaker, an implantable cardioverter defibrillator, icd, device is used, treating ventricular, lower heart chamber, arrhythmias, ventricular tachyarrhythmias, fibrillation, severity of these arrhythmias, cause sudden death, the dangerously fast heart rate, less often, internal cardioversion is needed to treat atrial, upper heart chamber)arrhythmias, in this case, device, an "atrial defibrillator", implantable defibrillators consist of a pulse generator that is implanted under the skin, a pacemaker, electrodes, wires, heart, heart goes into an abnormal rhythm, defibrillator, sense it, send an electrical shock, heart, to make it start beating, again, generator battery lasts, several years, complications, complications, relatively uncommon, internal defibrillators, bleeding, clot, vein, perforation, tearing, the heart, infection, lead dislodgement, wires not remaining where they were placed, shocks delivered by the device in error.
