Cardioversion Vs Ablation
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
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
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
Do you think Atrial Fibrillation would improve with an ablation? Only remedy so far is cardioversion
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?
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
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
Check list: I'm assuming this is for atrial fib? Full anticoagulation for at least 4 weeks. Nothing by mouth 4 hours before. Pads and monitor leads placed on chest and/or back. Iv line secured. Iv sedation. Synchronized cardioversion. Supervision till awake. Home. ...Read more
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
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
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
Opinion on going on a Cruise for 10days with AF. Just had cardioversion 8 weeks ago. Been 2years since previous episode.
Hi doc, I am a fifty year old male who has 3 to 4 AF attacks a year they are usually dealt with by cardioversion easily. This last time (3 weeks ago) I was not converted successfully. I always know the minute I go into AF and the minute I come out because
Question cut off: Please re-ask and clarify.Get a more detailed answer ›
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
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
