Synchronized electrical cardioversion may also be used to treat stable ventricular tachycardia (VT, vtach) that does not respond to a trial of intravenous medications. It is also recommended for the treatment of the following arrhythmias: Supraventricular tachycardia (SVT) due to reentry. Atrial fibrillation (AF, afib)
What rhythm requires synchronized cardioversion?
Jan 06, 2021 · What Is Synchronized Cardioversion? Synchronized cardioversion is a specific medical procedure used to restore a normal heart rhythm to a patient who is experiencing an arrhythmia, which is an irregular heart rhythm. During this procedure, a direct electric current passes through the patient’s chest, which shocks the heart.

What is cardioversion used to treat?
Electrical cardioversion can help treat several different abnormal heart rhythms. It is commonly used to treat atrial fibrillation (AFib). With this condition, the atria of the heart quiver instead of beating the right way. Symptoms of AFib may include shortness of breath, fatigue, and a very fast heartbeat.
When do you use synchronized cardioversion vs defibrillation?
Unlike defibrillation, which is used in cardiac arrest patients, synchronized cardioversion is performed on patients that still have a pulse but are hemodynamically unstable. It is used to treat both hemodynamically unstable ventricular and supraventricular rhythms.Mar 25, 2021

What is cardioversion and defibrillation?
There is an important distinction between defibrillation and cardioversion: Defibrillation — Defibrillation is the asynchronous delivery of energy, such as the shock is delivered randomly during the cardiac cycle. Cardioversion — Cardioversion is the delivery of energy that is synchronized to the QRS complex.Jan 21, 2022
What is the CPT code for cardioversion?
92960There is a specific CPT code, 92960, for such cardioversions. There are no separate codes or modifiers for using paddles or hands-free, and there are no special codes or modifiers for biphasic cardioversion. CPT code 92960 is for elective cardioversion, not defibrillation.Aug 8, 2017
What types of cardioversion are there?
There are two types of cardioversion. Chemical cardioversion uses medications that can relax an overactive heart. Electrical cardioversion uses one or more quick electric shocks to the heart. The shock is delivered through electrodes attached to the chest.
Is cardioversion always synchronized?
For cases where electrical shock is needed, if the patient is stable and you can see a QRS-t complex use (LOW ENERGY) synchronized cardioversion. If the patient is pulseless, or if the patient is unstable and the defibrillator will not synchronize, use (HIGH ENERGY) unsynchronized cardioversion (defibrillation).Jun 25, 2015
When do you use synchronized vs unsynchronized cardioversion?
Unsynchronized cardioversion is called for when the patient has no apparent electrical activity. In other words, they have pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF).Feb 24, 2022
What is the difference between synchronous cardioversion and asynchronous defibrillation?
Defibrillation or unsynchronized cardioversion is indicated in any patient with pulseless VT/VF or unstable polymorphic VT, where synchronized cardioversion is not possible. Synchronized cardioversion is utilized for the treatment of persistent unstable tachyarrhythmia in patients without loss of pulse.
What is an unsynchronized cardioversion shock?
Unsynchronized cardioversion (defibrillation) is a HIGH ENERGY shock which is delivered as soon as the shock button is pushed on a defibrillator. This means that the shock may fall randomly anywhere within the cardiac cycle (QRS complex).
What is QRS T complex?
For cases where electrical shock is needed, if the patient is unstable, and you can see a QRS-t complex use (LOW ENERGY) synchronized cardioversion. If the patient is pulseless, or if the patient is unstable and the defibrillator will not synchronize, use (HIGH ENERGY) unsynchronized cardioversion (defibrillation).
Can shocks cause VF?
If the shock occurs on the t-wave ( during repolarization), there is a high likelihood that the shock can precipitate VF (Ventricular Fibrillation). The most common indications for synchronized cardioversion are unstable atrial fibrillation, atrial flutter, atrial tachycardia, and supraventricular tachycardias.
How to perform synchronized cardioversion?
Before performing synchronized cardioversion, it is essential that appropriate precautions and steps be taken to increase the likelihood of a positive outcome. The first step is to identify the patient’s rhythm on the monitor. Take time to obtain a 12-lead EKG if the patient is stable and there is any doubt about the patient’s rhythm. Since cardioversion is painful, the patient will need to be properly sedated with intravenous medication. There is a wide diversity regarding the medication strategy to facilitate cardioversion, including hypnotic agents, sedative agents, and additional analgesics. The agent of choice is determined by many factors including the duration of sedation and recovery, the desired depth of sedation, the likelihood of undesirable cardiorespiratory effects, or recall of the procedure. 5
What is the difference between cardioversion and defibrillation?
What is the difference between cardioversion and defibrillation? Synchronized cardioversion involves the delivery of a low-energy shock which is timed or synchronized to be delivered at a specific point in the QRS complex ( see the image below). A synchronized shock is delivered at this precise moment to avoid causing or inducing ventricular fibrillation. 6 In this example, atrial fibrillation (AF) was converted to normal sinus rhythm (NSR) by the delivery of the electrical shock synchronized to the R wave on the QRS complex. The vulnerable T wave was avoided, which could convert this rhythm to ventricular fibrillation if the shock was delivered at that moment.
What is a defibrillator?
Defibrillation is used to treat certain types of arrhythmias (ventricular fibrillation and pulseless ventricular tachycardia). Synchronized cardioversion is used to treat other arrhythmias, including atrial fibrillation (AF), atrial flutter, and stable ventricular tachycardia when medications have failed to convert the rhythm, ...
Why isn't the ECG synchronized with the shock?
In this example, the delivered shock is not synchronized with the ECG because the rhythm is unstable and there is no apparent QRS complex or T wave to avoid. The rhythm was converted to NSR after the shock was delivered.
What equipment is needed for sedation reversal?
Additional airway management equipment should be easily accessible, such as an oral airway and intubation equipment. Some hospitals also have sedation reversal medications on standby to be used if needed. If necessary, the patient’s chest hair should be shaved at the site where the electrodes will be placed.
What determines the agent of choice?
The agent of choice is determined by many factors including the duration of sedation and recovery, the desired depth of sedation, the likelihood of undesirable cardiorespiratory effects, or recall of the procedure. 5.
Why do shocks need to be synchronized?
The reason a shock must be synchronized is that the cardiac cycle has both a vulnerable and a refractory period. The refractory period occurs during the QRS complex (see the image below). ECG. https://hyperphysics.phy-astr.gsu.edu/hbase/Biology/imgbio/ecg.gif. Accessed January 15, 2019.
What is cardioversion used for?
Cardioversion also treats other kinds of abnormal heartbeats, including atrial flutter, atrial tachycardia and ventricular tachycardia. Cardioversion or defibrillation is also used in emergency situations for people who suffer sudden life threatening arrhythmias.
Why do doctors use cardioversion?
Most often, doctors use cardioversion to treat a fast, irregular heart rhythm called atrial fibrillation. If you have electrical cardioversion, you’ll get medicine to put you to sleep so you don’t feel the shock.
How does an IV shock work?
You won’t feel pain during the procedure. Your doctor will deliver an electrical shock through two paddles. One is placed on your chest and the other on your back.
What is abnormal heart rhythm called?
Abnormal heart rhythms are called arrhythmias. Watch an animation of arrhythmias. There are two kinds of cardioversion. Your doctor may give you one or more medicines to bring back your regular heartbeat. This is called pharmacologic (chemical) cardioversion.
How many shocks do you need for a heart attack?
The shock lasts less than a second, and briefly stops (resets) your heart rhythm. Your doctor will check to see if your heartbeat is regular. Some people need only 1 shock .
What is it called when your heart beats irregularly?
If your heart has an irregular (uneven) beat or is beating too fast, cardioversion is a way to restore a regular rhythm. Abnormal heart rhythms are called arrhythmias. Watch an animation of arrhythmias. There are two kinds of cardioversion. Your doctor may give you one or more medicines to bring back your regular heartbeat.
Can cardioversion cause a stroke?
Cardioversion may knock loose a blood clot in your left atrium. If the clot (embolus) travels to your brain, it can cause a stroke. To avoid this, your doctor may give you medicine (such as warfarin) to make your blood less likely to form blood clots.
What is synchronized cardioversion?
Synchronized cardioversion is the recommended treatment for patients who have a symptomatic, unstable reentry SVT or V-tach with pulses. Synchronized cardioversion is also routinely used to treat unstable atrial flutter and unstable atrial fibrillation.
What is an unsynchronized shock?
Unsynchronized shocks refer to a shock that is delivered immediately after the healthcare professional pushes the shock button. This means that the shock is not delivered precisely in the cardiac cycle; in other words, unsynchronized shocks are more random. However, when a healthcare provider uses synchronized cardioversion, ...
How to increase energy level after tachycardia?
If tachycardia continues to persist, you should increase the energy level according to the Electrical Cardioversion Algorithm. Activate the sync mode. This should be done after each synchronized shock. Be aware that many defibrillators will default back to the unsynchronized mode after delivery of a synchronized shock.
How to treat unstable polymorphic V-tach?
If treating unstable polymorphic V-tach, you should treat it as VFib and deliver a high-energy shock. Make an announcement to the team members that you’re charging the de fibrillator and tell everyone to stand clear. Press the charge button. Make sure the patient is clear once more after the de fibrillator is charged.
Can cardioversion stop junctional tachycardia?
Cardioversion may not be effective when treating junctional tachycardia or ectopic or multifocal atrial tachycardia, as these rhythms have an automatic focus arising from cells that are spontaneously depolarizing at a rapid rate. In these scenarios, the delivery of a shock typically cannot stop these rhythms.
