Answer:It is important that you are aware of what was done. I would suggest you make an appointment and ask these questions of your EP.
Answer:This is debated and there is no consensus. I undertake a TOE before all AF ablation cases. The temperature set during the cases depends on what is being done. With irrigated ablation (mostly AF ablations done this way) the temperature is not so important as it is controlled by irrigation of fluid. The power delivered is what causes the lesion. I would need more specifics to be able to provide more information.
Answer:If your AF burden is 20% (ie you are in sinus rhythm the rest of the time) I would have a second ablation if you were symptomatic. Indeed, I counsel my patients that with current technology a significant proportion will need a second ablation. If they are not prepared for that then they should consider if they should have the first. I am not aware of a neurologist who is working in this area.
Answer:These are complicated questions and I am going to try and give you an interpreted response to each: 1. All heart tissue is capable of ectopic beats. For example, if you stretch a muscle it initiates ectopic activity. Under the correct exposure this occurs to cause AF - high blood pressure, sleep apnea, diabetes.......etc These are the risk factors known to cause AF. 2. All of the above conditions change the atrial muscle. There are ionic changes, structural changes and autonomic changes. Perhaps importantly there is fibrosis of the atrial muscle. This provides the environment to hinge wavefronts ....rotors, to facilitate ectopic beats....therefore maintaining AF. Answer: C - it is a lot more complex :)
Answer:The risk of stroke as a result of AF is very much dependent on the associated risk factors. These should be re-evaluated on a yearly basis. From a stroke prevention in AF perspective I do not believe there is any data on the two doses that you have suggested. Perhaps more important is whether you need anticoagulation. Your doctor will be able to discuss these with you.
Answer:If the ligation is not complete then it is not likely to protect you from stroke. The alternatives are to either consider oral anticoagulation (pros, cons and risks need to be discussed) or to attempt to achieve closure which is what has been suggested. Technically with some of the LAA gone it would be more difficult and so feasibility and success would depend on the imaging and the physician/centre experience.
Answer:You should check with your doctor as to what is the cause of your palpitations (feeling of abnormal heart beats). There are many different causes and the treatment varies with the cause. If atrial fibrillation is the cause, then flecainide may be an appropriate medication for you.
Answer:Only the doctor who is treating your father can answer these questions. There are many different types of medications to try, and also medical devices such as CRT pacemaker or cardiac assist devices.
Answer:You would need to wear a heart monitor such as a Holter or event monitor to make a recording when you are having the symptoms; then see your doctor to discuss the results.
Answer:53bpm is not a very slow heart rate and may not be the cause of your symptoms; you should see your doctor to arrange a 24 hour Holter monitor or an Event monitor.
