Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56?

Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56?

Neither. In clinical: Trials, carvedilol has significantly better outcomes than either metoprolol (e.g. 3%/yr lower mortality rates continuing for many years) or bisoprolol. Creatinine is quite another issue, produced by all muscle cells, yet used to crudely estimate renal filtering function, not the 4 known responses to carvedilol. Also the clinical trial data for all the Beta blockers is as augmenters to ACEI agents. ...Read more

Cardioversion?: Initially with rate control and anti-coagulation. If the atrial fibrillation is causing you symptoms, then a controlled and timed shock to the heart, called cardioversion, can be administrated tito regulate your heart. This is an outpatient procedure. Discuss with your doctor. ...Read more

I have been to the ER for a rapid heartbeat. Sometimes it's diagnosed as sinus tachycardia and sometimes atrial fibrillation. I have tried cardyzeme and metopral without much success. What happens if I don't seek treatment next time?

I have been to the ER for a rapid heartbeat. Sometimes it's diagnosed as sinus tachycardia and sometimes atrial fibrillation. I have tried cardyzeme and metopral without much success. What happens if I don't seek treatment next time?

I: I agree with dr. Guyton's excellent and thorough answer and would like to emphasize that with atrial fibrillation there are two main issues:
1) heart rate - a fast heart rate is typically what most people present with, and typically can be managed with medications to control heart rate such as the two you described, although there are others. Sustained high heart rates are not good for the heart, but as long as you are not having chest pain, shortness of breath, dizziness, or loss of consciousness then you can call your physician before rushing to the er.
2) stroke - afib presents a very real increase risk of stroke if not properly treated. For this reason, an accurate diagnosis is a must, and if it is indeed afib the you should discuss with your physician whether you are high enough risk to require blood thinners such as Coumadin (warfarin) or pradaxa. This is a long term risk so can be discussed in the outpatient setting with your docotor or a cardiologist. ...Read more

Is using flecanide with amiodarone effective incase of paroxysmal atrial fibrillation refractory to amiodarone 200 mg alone, what doses should be used?

Is using flecanide with amiodarone effective incase of paroxysmal atrial fibrillation refractory to amiodarone 200 mg alone, what doses should be used?

Zero guarantees. All: The Type 1 antiarrhythmic agents, as documented in the CAST Trial & analysis of other trials, neither work for most individuals (CAST Trial selected out the minorities for which these agents did decrease arrhythmias by Holter) increased mortality event rates. These agents promoted for symptoms, not health. Focus on underlying issues wiser. See: https://www. Healthtap. Com/#user_questions/689879. ...Read more

What is the loading oral dose cordarone (amiodarone) In old patient with atrial fibrillation returned to sinus rhythm and how to reduce its side effect?

Amiodarone: There are a number of schemes to load but to obtain levels one uses 800 mg for 5 day, 600 mg for 5 days, and 400 mg maintenance for 3-6 months and then attempt to lower dose to 200 mg daily. Side effects are followed by monitoring thyroid, chest X-ray and liver function as well as sun screen ...Read more

Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?

Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?

Afib/vfib: Ventricular standstill and fine v-fib are functionally the same the ventricle is not contracting - vfib is a slight quivering which may or may not be identifiable on ECG;

if the ventricle is not contracting then it is not possible to non-invasively identify atrial fibrillation from simply sinus/atrial arrest. ...Read more

Atrial fibrillation and psvt as well as blood sugar problems are possible diagnosis' for me but I am only 22 and am very active and healthy? How?

Need cardiac monitor: From your question, I assume you're having palpitations that have not yet been documented or diagnosed. You should have a 24-hour holter monitor, and possibly a long-term event monitor to see if it is a cardiac arrhythmia, and if so, what kind. ...Read more

Hoping you can tell me, is minimally invasive treatment for atrial fibrillation available?

Yes: All catheter-based techniques are considered minimally invasive. Conventional techniques are up to 75% effective though multiple procedures are frequently required. There is a mini-thoracotomy procedure they can do with slightly improved efficacy over this but it involves making a lot of scar tissue around the left atrium; we usually reserve that for people needing other procedures in the chest. ...Read more

How can food affect atrial fibrillation?

How can food affect atrial fibrillation?

Food can affect meds: Afib is a rythm that can be very fast and can cause a stroke from blod clots going to the brain. Many patients are on Coumadin (warfarin) a blood thinner that works through vitamin k. So if the patient eats green leafy veges and other foods high in vitamin k, it can reverse the Coumadin (warfarin) and make pt suseptable to stroke. Foods and items high in caffiene like coffee chocolate etc can stimulate the heart rate. ...Read more

How to know what is atrial fibrillation and is it serious?

Atrial fibrillation: Afib is a rapid irregular heart rhythm which can decrease heart efficiency as much as 20% in some patients. It can also be associated with clotting and clots travelling around the body to cause stroke or other problems. Some people have atrial fibrillation as their normal rhythm. Talk to your dr. About it if you have it. ...Read more

Is atrial fibrillation a serious condition? My friend is 45 and has it.

Not usually: Atrial fibrillation may be a consequence of structural abnormalities of the heart, which can indeed be serious. However, if the rhythm disturbance is the only abnormality then it can usually be controlled sufficiently that the patient can be free of symptoms. In older patients with af there is significant risk of stroke, but this too can be mitigated by treatment to reduce blood clots. ...Read more

Funny how a diagnosis doesn't mean much till you have it. What is atrial fibrillation?

Electrical chaos: The electrical impulses in the upper chambers of your heart (mostly originating from the left side) are completely chaotic leading to a quivering motion of these chambers instead of their typical, coordinated pumping function. The lower chambers beat erratically, as the electrical impulses bombard them in a haphazard way. See a cardiologist or an elelctrophysiologist. ...Read more

What is the difference between atrial fibrillation and nonvalvular atrial fibrillation?

Afib: Afib is the most common heart rhythm disturbance that we treat as cardiologists and can occur in a number of clinical settings and in association with other diseases both cardiac and non-cardiac. Non-valvular atrial fibrillation refers to atrial fibrillation that does not occur in the setting of mitral valve disease such as mitral stenosis or mitral regurgitation. ...Read more

Can stress cause atrial fibrillation?

Can stress cause atrial fibrillation?

Generally, not: If there is no underlying cardiac problems that may predispose one to atrial fibrillation, it would be unusual for stress to be actual cause; however stress can be the underlying to so many maladies, that one never says never. If one develops atrial fib, must look for underlying heart disease, and--even it none is found-be treated for it by cardiologist specializing in cardiac rhythm disorders. ...Read more
