What is the difference between defibrillation and cardioversion

The only drawback is that they take around seconds to analyse the rhythm which can be critical. Semi-automated external defibrillators are similar except that they can be controlled manually when operated by a trained paramedic. They can pace the heart rate. These machines have an ECG display which helps in resuscitation. Internal defibrillators are seen in the operation rooms where they are used to restore heart beat during an open heart surgery.

The paddles are placed above and below the heart and the shock is given. Automatic internal cardiac defibrillator AICD is implanted under the skin in the chest area.

They constantly monitor the rhythm of the heart. Upon sensing any irregularities in the rhythm, it immediately sends shocks to the heart muscles and restores normal heart rate. To summarize cardioversion and defibrillation both restore normal heart rate with defibrillation being the procedure of choice in a cardiac emergency. Rate this post!

Difference Between Similar Terms and Objects. It is also possibly indicated after failed pharmacologic therapy for the previously mentioned arrhythmias, especially if the patient becomes hemodynamically unstable.

Cardioversion should be synchronized, which means the electric current will be timed with the patient's intrinsic QRS complexes , to minimize the risk of inducing VF. Electrical energy can terminate an abnormal rhythm, but if inappropriately delivered, it can also induce VF. This can happen if the electric shock is delivered during the relative refractory portion of the cardiac electrical activity.

When preparing for defibrillation, check the patient and rhythm to ensure that a shock is truly indicated. Movement artifacts or loose leads may look like VF. New defibrillator technology is available that can filter compression or movement artifacts to "see through" the underlying rhythm. However, when using automated external defibrillators AEDs , all manufacturers currently still recommend stopping all compressions and patient movement e.

Make sure that no rescuer is inadvertently in contact with the patient when a shock is delivered. Neither single nor double gloves provide the rescuer with complete safety from current, 2 so we still recommend "stand clear" drills during defibrillator training, "stand clear" practice during actual defibrillation, and minimizing rather than eliminating the pause in compressions for defibrillation. If the patient is on a wet or conducting surface, move the patient to a safe area and dry the body before delivering the shock.

When using manual defibrillation paddles, make sure that the paddles are either on the Your MyAccess profile is currently affiliated with '[InstitutionA]' and is in the process of switching affiliations to '[InstitutionB]'.

In this article Description Defibrillation Cardioversion. Description 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.

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.

It is also used in less urgent cases - eg, atrial fibrillation AF - to try to revert the rhythm back to sinus. If the shock happens on the t-wave during repolarization , there is a fair risk that it can cause VF Ventricular Fibrillation. Unstable atrial fibrillation, atrial flutter, atrial tachycardia, and supraventricular tachycardias are the most common signs of coordinated cardioversion.

If drugs fail to control the arrhythmias in a stable patient, coordinated cardioversion would almost certainly be needed.

This means that the shock can occur at any time during the cardiac cycle QRS complex. If the patient is stable and a QRS-t complex can be seen, use low energy synchronized cardioversion in cases where electrical shock is needed. It is therefore safe to say that unsynchronized cardioversion and defibrillation are the same things. The term unsynchronized cardioversion is just a more accurate term used to describe the process of what defibrillation really is.

A pulse that is too rapid tachycardia or erratic may be corrected with cardioversion fibrillation. Cardioversion is often used to treat patients with atrial fibrillation or flutter.

When the electrical signals that usually cause your heart to beat at a regular pace do not propagate correctly through the upper chambers of your heart, these conditions occur.

Cardioversion is typically performed in advance, but it can also be done in an emergency. Your doctor can see right away whether the operation has restored a natural heartbeat with electric cardioversion.

Electric cardioversion takes less time than medication-only cardioversion. Cardioversion is not to be confused with defibrillation, which is an emergency treatment used when the heart slows or quivers ineffectively.

Defibrillation shocks the heart with more intense shocks to adjust its rhythm. Although experiencing any complications when it comes to cardioversion is very rare, there are still some present. You should be aware that your doctor should take all the necessary precautions in order to reduce the chance of any of these risks occurring; however, these are some of the complications that could occur:.

Cardioversion procedures can be administered during pregnancy; however, it is recommended that the heartbeat of the baby is monitored throughout the entire process in order to ensure that they do not have any negative reactions to the procedure being done. Cardioversion procedures are usually planned ahead of time.

If your symptoms are serious, you can need cardioversion in a hospital emergency room. Before your procedure, your doctor can tell you whether or not you should take any of your regular medications. If you must take drugs prior to your operation, just drink enough water to allow you to swallow your pills. A transesophageal echocardiogram can be performed prior to cardioversion to check for blood clots in your heart.

Cardioversion can cause blood clots to break free, posing a life-threatening risk. Until cardioversion, your doctor assesses if you need a transesophageal echocardiogram. If blood clots are discovered, the cardioversion operation can be postponed for three to four weeks. Other drugs can be administered through IV to aid in the restoration of your heart rhythm. On your chest, a nurse or technician positions numerous large patches known as electrodes. Wires attach the electrodes to a cardioversion system defibrillator.

The machine tracks your pulse and sends shocks to your heart to bring it back to normal. If your heart beats too slowly after cardioversion, this machine can fix it. After you have been sedated, the process of electric cardioversion usually only takes a few minutes to complete. Electric cardioversion is performed as an outpatient procedure, which means you can go home the same day. You should spend an hour or two in a recovery bed, where problems can be closely monitored.

You could most probably need someone to bring you home, and your decision-making abilities may be impaired for several hours after your treatment. Even if no clots were detected in your heart prior to your operation, you need to take blood thinners for at least a few weeks afterward to prevent new clots from forming.
