Developed arythmia 18 months ago. Didn't have insurance at the time, so I let it go. Was still able to run, play soccer, swim. My Prime care physician recommended cardioversion....but that failed twice. Finally, Oct 1st of 2014, I had a 6 1/2 hour ablatio

Happy to help but: Can you try to focus in on the question but limited too much information, as otherwise it's unclear as to exactly what your question is. If you feel like it is rather complex, consider a formal consultation through HealthTap Prime. ...Read more

Ablation (Definition)

Cardiac ablation involves destruction of tissue aimed at elimination of sources of origin or propagation of arrhythmias. It may also be used to destroy part of the heart in hypertrophic cardiomyopathy. Typically it is done with a catheter inserted through a ...Read more

Can I have cardioversion for paroxsysmal AF if I had a pacemaker? Or should I have ablation?

Can I have cardioversion for paroxsysmal AF if I had a pacemaker? Or should I have ablation?

Either procedure is: safe for you with a pacemaker but you will need to review your history of treatment for afib with your health care provider to decide which one or both are appropriate for your management. ...Read more

Which is better for an atrial flutter: cardioversion or ablation?

Which is better for an atrial flutter: cardioversion or ablation?

Define better please: What does better mean? Initial atrial flutter ablation success rates run around 80-85%. This for the typical flutter variety. A form of atrial flutter called atypical atrial flutter has a much lower success rate. But ablation is invasive, meaning there is inherent risk such as perforation of the heart, pericardial effusion, need for permanent pacemaker implantation, etc. Such risks are very rare ...Read more

Is cardioversion or ablation more effective for treating an atrial flutter?

Cardioversion/ablati: Cardioversion is used to treat individual episodes if they don't recurr frequency, if chronic or recurrent atrial flutter is present, then ablation attempts to prevent the rhythm from recurring long term hopefully permanently. ...Read more

Do you think Atrial Fibrillation would improve with an ablation? Only remedy so far is cardioversion

Do you think Atrial Fibrillation would improve with an ablation? Only remedy so far is cardioversion

Yes: RF ablation for atrial fibrillation and/or atrial flutter in good hands ought to be curative. Factors that determine success: electrophysiologists experience and record of success, duration of AF; size and function of Left atrium. Good luck! ...Read more

My father has persistent afib despite cardioversion and medication. What are some complications to take into consideration with ablations?

My father has persistent afib despite cardioversion and medication. What are some complications to take into consideration with ablations?

See below: The most common complication is recurrent AF despite successful ablation. A 2nd procedure will improve the odds but not to 100%. Pulmonary vein stenosis is a rare but serious complication which can be helped with percutaneous dilitation. Cardiac perforation with tamponade is very rare but potentially dangerous if unrecognized. Despite the above, the vast majority of patients do very well. ...Read more

I have had cryo-ablation three cardioversions and still Afib, Now want to do an ablation with heat and start tikosyn. would a pacemaker be better?

2nd opinion: Believe it is time for you to get a 2nd opinion to find out what may be a better option for you given that 3 attempts on ablation have failed. ...Read more

What is a sync cardioversion?

Timed shock: This is a cardioversion (shock) given to the heart that is timed to a certain point in the cardiac cycle so that the heart rhythm can be reset without causing further rhythm problems. This is the most common type of shock delivered for rhythms such as atrial fibrillation. ...Read more

Cardioversoin: Electrical cardioversion doesn't work in every situation and for instance atrial fibrillation with a very large left atrium is very difficult to cardiovert. Depends on what your situation is... ...Read more

How is a cardioversion administered?

With paddles: The patient is sedated in preparation for the shock.

Paddles are placed on the chest once the patient is asleep, and a properly timed shock is delivered to restore normal rhythm.

Sedation is allowed to wear off. ...Read more

How many watts are used for cardioversion?

How many watts are used for cardioversion?

Cardioversion: We generally administer electrical cardioversion in watt-seconds or joules. For afib we usually use a synchronized shock of 100-200 watt-seconds, depending on patient size and other factors. For vfib at least 200 watt-seconds. Modern systems use a biphasic system. ...Read more

How effective is cardioversion in helping af?

A good start: Cardioversion is a great first step in managing AF. The procedure is generally very low risk and is highly effective at restoring normal rhythm.

The hard part is maintaining normal rhythm. The heart tends to want to go back into AF without rhythm controlling medications or elimination of the trigger for AF (such as excess alcohol, uncontrolled blood pressure, sleep apnea, etc.). ...Read more

How effective is cardioversion for helping af?

How effective is cardioversion for helping af?

Effective: If the patient is an appropriate candidate: symptomatic, af unresolvable by medication only, other medical factors the cardiologist will consider, then yes, cardioversion is effective for regaining normal sinus rhythm. Like all therapies, it is not 100% effective and must be evaluated for each individual patient. ...Read more

Is DC cardioversion induce ST elevation or not?

Cardioversion: Usually DC Cardioversion does not cause ST elevation if the Cardioversion is in a heart not inflamed or infarcted. Having said that, ST segment elevation could occur if the heart is injured by the current. ...Read more

How serious is SVT if someone had chemical cardioversion?

How serious is SVT if someone had chemical cardioversion?

Not usually serious: That type of rhythm problem is usually more of a nusance than serious. It can at times be hard to treat as far as preventing recurrences but except for the nusance aspect is usually pretty benign. It would be helpful to know the exact mechaism of the rhythm problem and the heart rate in answering your question. ...Read more

Why is a stress test administered after a dc cardioversion?

Why is a stress test administered after a dc cardioversion?

It depends: It is not typical to require a stress test after a cardioversion. Sometimes it is important to evaluate for possible underlying causes of a rhythm problem including coronary artery disease. At other times, it is important to evaluate for possible side effects to antiarrhythmic drugs via stress testing. ...Read more

What are the differences between asynchronous and synchronous cardioversion?

Heart Cycle: Synchronous is when the shock is delivered on the qrs portion of the heart cycle - it is when the heart depolarises. Asynchronous cardioversion can occur anywhere on the heart cycle. ...Read more

Who can have cardioversion?

Who can have cardioversion?

Almost anyone: If there is any compromise in bp, consciousness, breathing, anyone can be cardioverted. If more chronic, then making sure there is a low probability of a clot inside the heart (that could be disrupted and cause an embolic event), sorting the need for prophylactic blood thinning to avoid a clot, making sure the atria (upper heart chambers) are not too large (reduced success) help select patients. ...Read more

What's next if cardioversion didn't work?

What purpose is dc shock for cardioversion?

What purpose is dc shock for cardioversion?

Reset button: Enough current applied through the chest wall and into the heart will basically depolarize all of the heart muscle at once. As the heart electrically recovers, "normal" electrical activity has a chance to return - basically it resets the electrical activity of the heart. ...Read more
