What is an Elective Cardioversion slide 1 of 6. A cardioversion is a procedure that returns an irregularly beating heart (arrhythmia) to a normal (sinus) rhythm. To do this, a carefully controlled electrical impulse is delivered to the heart. Heart arrhythmias are not unusual and many are not serious and require no treatment.

Cardioversion Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs.Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.ynchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present.

- In these cases, the patient's cardiologist may recommend an elective (non-emergency) cardioversion. 1  slide 1 of 6. A cardioversion is a procedure that returns an irregularly beating heart (arrhythmia) to a normal (sinus) rhythm. 2  slide 2 of 6.

- Cardioversion can be done using an electric shock or drugs. Electric cardioversion may be done with a device that gives off a shock. The device can be placed inside (internal) or the shock can be delivered from the outside (external) the body. External electric cardioversion uses a device called a defibrillator.

Cardioversion 1 Arrhythmias may prevent blood from circulating properly to your heart and brain. 2  Most often, doctors use cardioversion to treat a fast, irregular heart rhythm called atrial fibrillation. 3  If you have electrical cardioversion, you’ll get medicine to put you to sleep so you don’t feel the shock.

What Is Cardiac Ablation? This is a procedure to treat atrial fibrillation (AFib), a type of irregular heartbeat. It can help keep your heartbeat in a normal rhythm. Your doctor may try ablation if medications or resetting your heartbeat, called cardioversion, don’t work.

Electrical Cardioversion (Defibrillation) for a Fast Heart Rate Electrical Cardioversion (Defibrillation) for a Fast Heart Rate. Treatment Overview. Electrical cardioversion is a procedure in which a brief electric shock is given to the heart to reset the heart rhythm back to its normal, regular pattern (normal sinus rhythm). The shock is given through patches applied to the outside of the chest wall. In some situations an external defibrillator, which has paddles, might be used.

- Electrical cardioversion risks include: 1  skin burns. 2  fluid in the lungs. 3  heart attack, stroke, or - as with most procedures - death.

- Non-emergency cardioversion may be used to treat the following conditions: 1  Atrial fibrillation —very rapid, irregular quivering in the atrium; ventricles pump irregularly. 2  Atrial flutter —rapid but regular contractions in the atrium, when the ventricular heart rate is not too fast.

Electrical Cardioversion A problem with any part of this process can cause an arrhythmia. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Doctors use cardioversion to correct fast or irregular heartbeats. Cardioversion is done two ways: using an electrical procedure or using medicines. For the electrical procedure, your heart is given low-energy shocks to trigger a normal rhythm. You're temporarily put to sleep before the shocks are given. This type of cardioversion is done in a hospital as an outpatient procedure.

Defibrillation Subsequently, the body's natural pacemaker in the sinoatrial node of the heart is able to re-establish normal sinus rhythm. In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle. Although the person may still be critically ill, cardioversion normally aims to end poorly perfusing cardiac dysrhythmias, such as supraventricular tachycardia.

Cardiopulmonary bypass Cardiopulmonary bypass is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the patient's body. The CPB pump itself is often referred to as a heart–lung machine or the pump. Cardiopulmonary bypass pumps are operated by perfusionists. CPB is a form of extracorporeal circulation. Extracorporeal membrane oxygenation is generally used for longer-term treatment.

Synchronized Electrical Cardioversion Cardioversion is defined as a “synchronized DC discharge, and … does not apply to ventricular defibrillation or to the pharmacologic reversion of arrhythmias.”The DC electrical discharge is synchronized with the R or S wave of the QRS complex.

Medical Definition of Cardiopulmonary bypass Cardiopulmonary bypass: Bypass of the heart and lungs (for example, during open-heart surgery). Blood returning to the heart is diverted through a heart-lung machine (a pump-oxygenator) before it is returned to the arterial circulation. The machine does the work of both the heart and the lungs, by pumping blood as well as supplying oxygen to red blood cells.

Cardiac ablation procedures Cardiac ablation is a procedure that is used to scar small areas in your heart that may be involved in your heart rhythm problems.

- Cardiac catheterization (also called cardiac cath or coronary angiogram) is an invasive imaging procedure that allows your doctor to evaluate your heart function. Cardiac catheterization is used to: 1  Evaluate or confirm the presence of coronary artery disease, valve disease or disease of the aorta.

Maze Procedure Thorascopic off-pump (TOP) surgical ablation (also known as mini Maze procedure, absent thoracotomy Maze procedure) is performed on a beating heart -- the heart is not arrested via bypass.etna considers minimally invasive, off-pump Maze procedures, also known as thoracoscopic off-pump surgical ablation (TOPS), experimental and investigational for atrial fibrillation or flutter because there is insufficient evidence of their effectiveness. See also CPB 0019 - Holter Monitors.

- An External Cardioversion is a procedure used to treat someone’s heart that is beating either too fast or in an irregular rhythm such as atrial fibrillation or atrial flutter. The heart is shocked in order to restore the normal electrical activity of your heart.

Prevention and Therapies Cardioversion is the use of a defibrillator when a person is not in cardiac arrest but has an abnormal heart rhythm. Sometimes the team will try to shock a heart back into a normal rhythm. The patient will be given sedatives and pain relief before undergoing cardioversion.

What is Ablation Surgery Cardiac Ablation Surgery Procedure. Cardiac Ablation Surgery is performed by placing catheter tubes. A vein in forearm, groin or neck is selected and catheter is inserted into it and moved to the upper part of the heart where the abnormal heart rhythm or arrhythmia occurs.

Overview Electric cardioversion takes less time than cardioversion done solely with medications, and your doctor can instantly see if the procedure has restored a normal heartbeat. If your doctor recommends cardioversion with medications to restore your heart's rhythm, you won't receive electric shocks to your heart.

Experience Counts One-third of Clonazepam patients will develop tolerance to the drug in 2-4 weeks and will suffer from the Benzodiazepine Withdrawal Syndrome, a grouping of extremely painful symptoms that can last many months.

- Cardioversion is the delivery of an electric shock to the chest through electrodes or paddles. The shock is given to correct a dangerous heart rhythm. Cardioversion can be done as an elective (scheduled) procedure or may be done urgently if an abnormal heartbeat is immediately life-threatening.

Synchronized Electrical Cardioversion Internal cardioversion for atrial fibrillation is used in patients who are resistant to external cardioversion or inadvertently induced during an electrophysiologic study. Cardioversion should occur before placement of an atrial defibrillator.

- For patients who need to undergo elective cardioversion before they are able to take an anticoagulant effectively for three to four weeks beforehand, a transesophageal echocardiogram (TEE) is often performed before the cardioversion to be sure that there is no clot already formed in the heart.
