Defibrillators

Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart. Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat. They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. If the heart suddenly stops, defibrillators can also help it beat again. How serious is getting a defibrillator? As with all surgeries, a defibrillator implant involves risks and possible complications. Complications may become serious and life threatening in some cases. Complications can develop during surgery or recovery. Electrical cardioversion is used when the patient has a pulse but is either unstable, or chemical cardioversion has failed or is unlikely to be successful. These scenarios may be associated with chest pain, pulmonary oedema, syncope or hypotension.
