are cardioversion and defibrillation the same?
529066
Electrical cardioversion and defibrillation are procedures in the management of patients with cardiac arrhythmias. Cardioversion is the delivery of energy that is synchronised to the QRS complex, while defibrillation is the non-synchronised delivery of a shock randomly during the cardiac cycle.

An AED, or automated external defibrillator, is used to help those experiencing sudden cardiac arrest. It's a sophisticated, yet easy-to-use, medical device that can analyze the heart's rhythm and, if necessary, deliver an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm.

Defibrillation - is the treatment for immediately life-threatening arrhythmias with which the patient does not have a pulse, ie ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Cardioversion - is any process that aims to convert an arrhythmia back to sinus rhythm.

Implantable cardioverter-defibrillator An ICD works to regulate your heartbeat by delivering shocks to your heart when it detects an abnormal heartbeat. Usually, the procedure to implant an ICD can be performed with numbing medication and a sedative that relaxes you but allows you to remain aware of your surroundings.

Defibrillators. Defibrillators are devices that restore a normal heartbeat by sending an electric pulse or shock to the heart. They are used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart's beating if the heart suddenly stops.

Definition. Defibrillation is a process in which an electronic device sends an electric shock to the heart to stop an extremely rapid, irregular heartbeat, and restore the normal heart rhythm.

Regular defibrillation does not leave any marks or scars. ... Defibrillation only works when there is pre-existing electrical activity in the heart, if the patient doesn't have any electrical activity ('flat-lining') resuscitation it achieved with drugs and CPR.

A defibrillator uses static electricity to restart their heart. It is a procedure that does not always work but it has saved many lives. Portable and implanted defibrillators allow a more rapid response and help to save even more lives.

The ICD can quickly detect life-threatening abnormal heartbeats (arrhythmias). It is designed to convert any abnormal heart rhythm back to normal by sending an electrical shock to your heart. This action is called defibrillation. This device can also work as a pacemaker.

In simpler configurations, standard single or dual chamber ventricular defibrillators have been used for atrial defibrillation purposes. In such systems, the shock vector configuration between the ventricle and the pectoral ICD usually includes the atria and therefore, successfully terminates atrial fibrillation.

Defibrillators usually are implanted through small incisions in the skin, near the collarbone. You receive a mild sedative, but you're kept awake; a local anesthetic is used. An electrophysiologist will perform the procedure.

Defibrillation reverses the cardiac arrest by sending an electrical current through the heart muscle cells, momentarily stopping the abnormal electrical energy and allowing the normal heart beat to resume. ... Greater than 50-70% of Sudden Cardiac Arrest victims survive if defibrillation occurs within the first 5 minutes.

All defibrillators serve the same purpose. They are meant to administer an electrical shock to get the heart beating the way it should. While an AED is a type of defibrillator, it is by no means the only type. ... Manual defibrillators have capabilities that automated models do not.

These early defibrillators used the alternating current from a power socket, transformed from the 110–240 volts available in the line, up to between 300 and 1000 volts, to the exposed heart by way of "paddle" type electrodes.

This is not normal medical practice, as the heart cannot be restarted by the defibrillator itself. Only the cardiac arrest rhythms ventricular fibrillation and pulseless ventricular tachycardia are normally defibrillated.

Cardiac arrest is the abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease. It can come on suddenly, or in the wake of other symptoms. Cardiac arrest is often fatal, if appropriate steps aren't taken immediately.

An automated external defibrillator (AED) is a lightweight, portable device that delivers an electric shock through the chest to the heart. The shock can potentially stop an irregular heart beat (arrhythmia) and allow a normal rhythm to resume following sudden cardiac arrest (SCA).
