Doctor insights on:
Dofetilide: Tikosyn (dofetilide) is one of the medications we use for rhythm control in atrial fibrillation. All these medicines have statistical risk associated with their use. They are approved for use in humans which means used properly the risk is low. Used in the wrong person the risk could be significant. Discuss with the doctor prescribing for information specific to an individual. ...Read more
Depends: If it's working, one could use this over the long term. The caveat is that you should have routine stress testing done while on the medication. Also, as you get older your actuarial risk of coronary artery disease increases. The main contraindication to using flecainide is coronary artery disease, so some doctors don't like to maintain elderly patients on flecainide. ...Read moreSee 1 more doctor answer
Why do you take betapace, xocor, digoxin, and Coumadin (warfarin) with atrial fibrillation and sinus tachycardia?
Prevent stroke: Actually atrial fibrillation and sinus tachycardia are two completely different heart rhythms. None of these drugs would be of any use for sinus tachycardia. In atrial fibrillation, Betapace may restore a normal rhythm. Digoxin can help keep the heart rate down. Coumadin (warfarin) reduces the risk of stroke. Zocor also reduces stroke risk in some patients, but this is unrelated to the atrial fib. ...Read moreSee 1 more doctor answer
Digoxin: we have used it for hundreds of years, recently it has been falling into disfavor. It needs to be used with great care and this may be why recent usage problems are seen. It is an ancient poison so it can't be taken lightly. ...Read more
83 yrs f; stable diastolic hf; rate controlled a-fib. Meds: cardizem, coumadin, (warfarin) lasix, inderal, spiriva (mild copd). Would a cardioselective betablocker be better than inderal ?
Theoretically yes: In patients with COPD or asthma , cardioselective beta blockers like atenolol are felt to be superior to Inderal (propranolol) which also has possible harmful effects on the bronchial tree and could produce wheezing(bronchospasm). This may be a concern in someone like you who has copd. Your physician is best to advise you, however especially if you're doing well on inderal (propranolol). ...Read moreSee 1 more doctor answer
No: My answer would be NO. I reviewed reliable sources and atrial fibrillation is not listed as a side effect. I found a website with a very unscientific survey among people taking lisinopril who have developed afib, but without any scientific rigor at all. Most people that need lisinopril already have other reasons to develop atrial fibrillation. I hope this helps. ...Read more

Variable: These medications are older antiarrythmics that have been around for decades and may suppress af. They must be used very cautiously and only by very experienced cardiologists, due to their potential to actually cause potentailly life threatening ventricular arrythmias in certain patients - called a pro-arrthymic effect..Newer medications have been shown to be both safer and more effective. ...Read moreSee 1 more doctor answer
Reverses Ht Failure: Toprol xl (specifically that formulation, not metoprolol tartrate) and Carvedilol (generic or Coreg (carvedilol) brand name) have been shown in large, well controlled clinical trials to slow and sometimes reverse the damage of heart failure. They operate by blocking a malfunctioning feedback loop of hormones and signaling molecules, ultimately by blocking the effect of adrenaline on the heart. Good question! ...Read more
