How is cardioversion done?
Cardioversion is usually done by sending electric shocks to your heart through electrodes placed on your chest. It's also possible to do cardioversion with medications. Cardioversion is usually a scheduled procedure that's performed in a hospital. You should be able to go home the same day as your procedure.
What is the name of the machine that records your heart rhythm?
A nurse or technician places several large patches called electrodes on your chest. The electrodes connect to a cardioversion machine (defibrillator) using wires. The machine records your heart rhythm and delivers shocks to your heart to restore a normal heart rhythm. This machine can also correct your heart's rhythm if it beats too slowly after cardioversion.

What happens when the electrical signals that normally make your heart beat at a regular rate don't travel properly through the?
These conditions occur when the electrical signals that normally make your heart beat at a regular rate don't travel properly through the upper chambers of your heart. Cardioversion is usually scheduled in advance but is sometimes done in emergency situations.
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 people have cardioversion?
People have non-emergency or elective cardioversion to treat arrhythmias. The electrical signals that control your heartbeat start in the upper right chamber of your heart (atrium). In atrial fibrillation, very fast, irregular electrical signals move through both of the upper chambers of your heart. This can make your heartbeat fast and irregular. Some people who have atrial fibrillation don’t notice any changes in the way they feel. But others feel:
What are the risks of cardioversion?
If you have atrial fibrillation, blood clots can form in your heart’s left atrium. 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. If your doctor gives you the medicine, you’ll need to take it for 2 to 3 weeks before the procedure. Transesophageal echocardiography (TEE) is often used to check for the presence of blood clots before this procedure.
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 are the determinants of cardioversion?
(13) The major determinants of current delivery are: 1) the nature of the shock waveform (mono or biphasic) 2) level of delivered energy. In terms of shock waveform, both monophasic and biphasic waveforms are used.
What is 39 cardioversion?

(58) In another study, in-hospital treatment with oral propafenone started two days before direct current decreased early recurrence of atrial fibrillation after shock.
What is the best way to convert atrial fibrillation into sinus rhythm?
Direct current cardioversion is one of the most effective means of converting atrial fibrillation into sinus rhythm. Medical cardioversion is one alternative. However, direct current cardioversion has the highest overall success rate. (1,2) In all, patients who require cardioversion will often undergo direct current cardioversion rather ...
What is the success rate of direct current cardioversion?
Direct current cardioversion success rates vary from 75% to 93%. They are inversely related to the atrial fibrillation duration, chest wall impedance, and left atrial size. (3-7) Indeed, success rates vary according to the point in time that success is defined. In one series of 1,838 direct current cardioversions, success rates were 84%, 78%, 77%, and 66%, respectively, (8) when the duration of AF was <30, 30 to 90, 90 to 180, and >180 days. When atrial fibrillation has been present for more than five years, success rates are only approximately 50%. (9)
Is cardioversion a procedure?
While the indications for cardioversion in atrial fibrillation are widely communicated in the literature, the procedure itself is seldom described . Here we will review basic principles and techniques of direct current and internal cardioversion, from patient preparation to requirments for energy waveforms and paddle positioning, as well as complications, implantable devices and pretreatment with antiarrhythmic drugs.
Is direct current cardioversion effective?
Conclusions. Direct current cardioversion is an effective means of restoring sinus rhythm in patients with atrial fibrillation - improving patient outcomes is, thus, usually in our hands. Attention to proper technique for direct current cardioversion has the power to optimise efficacy.
What is cardioversion in heart?
Cardioversion is a procedure that can be used to correct many types of fast or irregular heart rhythms. The most common of these are atrial fibrillation and atrial flutter. Cardioversion is also used to correct ventricular tachycardia, which is a very fast, life-threatening heart rhythm that starts in the lower chambers of the heart (ventricles).
Where is cardioversion done?
The cardioversion will likely be done in the electrophysiology (EP) lab.
How does a defibrillator work?
The shock interrupts the abnormal electrical rhythm and restores a normal heart rhythm. It may take several shocks to get the rhythm back to normal.
What is EKG in medical terms?
ECG/EKG: Keeps track of your heart’s electrical activity. Several sticky patches (electrodes) are attached to your chest, and wires carry the information to a machine that creates a graph.
Can you take Coumadin on cardioversion?
Please ask your doctor how you should take your blood thinners/anticoagulants, such as Coumadin (warfarin), and your diabetes medications or insulin on the day of your cardioversion. Unless your doctor or nurse tells you otherwise, take all other regular medications as scheduled.
Is cardioversion part of a plan of care?
Cardioversion is only one part of your plan of care. It is also important for you to take your medications, a heart-healthy lifestyle and keep your follow-up appointments. Please talk to your doctor if you have any questions or concerns.
How to treat atrial fibrillation?
Treatment for atrial fibrillation may include medications, therapy to reset the heart rhythm and catheter procedures to block faulty heart signals.
What causes an increased risk of atrial fibrillation?
Heart disease. Anyone with heart disease — such as heart valve problems, congenital heart disease, congestive heart failure, coronary artery disease, or a history of heart attack or heart surgery — has an increased risk of atrial fibrillation.
What is the electrical connection between the atria and the ventricles?
In atrial fibrillation, the signals in the upper chambers of your heart are chaotic. As a result, they quiver. The AV node — the electrical connection between the atria and the ventricles — is bombarded with impulses trying to get through to the ventricles.
What is the signal that sends blood out of the heart?
In a typical heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal (sinus node impulse). The signal follows a specific path through the upper chambers (atria) and into the lower chambers (ventricles), causing them to squeeze and pump out blood. In atrial fibrillation, electrical signals fire from many areas in the atria, causing the chambers to beat chaotically. Some or all of these chaotic signals enter the ventricles, causing a fast, irregular heartbeat.
Is atrial fibrillation life threatening?
Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment. A major concern with atrial fibrillation is the potential to develop blood clots within the upper chambers of the heart.
What is the normal heart rate?
The normal range for a heart rate is 60 to 100 beats a minute. Your heart is made up of four chambers — two upper chambers (atria) and two lower chambers (ventricles). Within the upper right chamber of your heart (right atrium) is a group of cells called the sinus node. This is your heart's natural pacemaker.
Which chronic conditions increase the risk of atrial fibrillation?
Other chronic health conditions. People with certain chronic conditions such as diabetes, metabolic syndrome, chronic kidney disease, lung disease or sleep apnea have an increased risk of atrial fibrillation.
