Doctor insights on:
I, II, III and IV: Class i is divided into ia, ib, and ic. These are sodium channel blockers. An example from this class would be propafenone. Class ii agents are beta-blockers (like metoprolol). Class iii are potassium channel blockers - for example, amiodarone. Class IV are calcium channel blockers, like diltiazem. ...Read more
Vaughan-Williams: What you are referring to, i believe, is what is called the vaughan-williams classification (circa 1970) of anti arrhythmic drugs. Class i drugs block sodium channels on the cells, class ii drugs block beta-receptors, class iii drugs block potassium channels, and class IV drugs block calcium channels. Digoxin does not fit the vaughn-williams classification, as its properties are different still. ...Read moreSee 1 more doctor answer
I taken flecainide. Before CABG, flecainide changed to amiodarone for a week. after CABG, may directly converted amiodron to other antiarrhythmic drug?
Which anti-arrhythmic medication is best to control frequent, non-sustained, monomorphic ventricular arrhythmias with a structurally NORMAL heart ?
May need nothing: Unless causing symptoms or a cardiologist finds some.underlying abnormality what you describe does not need treatment. Caffeine, lack of sleep, stress, alcohol and decongestants like pseudofed, and energy drinks will all exacerbate the problem. If it needs treatment a beta blocker like Metoprolol or Coreg (carvedilol) are good choices Too much thyroid medication can bring this out as well. ...Read more
Is standard Mucinex (guaifenesin) safe with my current health conditions and medications (specifically the anti-arrhythmic). I Have mucous in lungs from virus.
Unlikely: Atrial fibrillation does not usually lead to VF unless the person also has WPW syndrome. If one has not been diagnosed with WPW, the chances of atrial fibrillation going into ventricular fibrillation is very low. Of course, if one has a fast heart rate for a long time, one can develop CHF and then possibly VF, but not because of the AF. Rate control prevents CHF or retards its development. ...Read moreSee 5 more doctor answers
I'm interested in starting Plexis Slim. However, I do take an anti arrhythmic drug:multaq. Will Plexis slim interact with Multaq?
Yes -- don't use it : It has been associated with cardiac arrhythmias, for which you're being treated. It may also result in kidney damage. Stay away from all such "snake oil" agents. They're hyped as "all natural", as if that means 100% safety. Arsenic, lead, and poisonous mushrooms are also all natural. Anyone trying to sell you something has a conflict of interest. ...Read more
Channel Poisons.: All antiarrhythmic medications are targeted at the channels that allow sodium, potassium, and calcium into and out of cardiac muscles, myocytes. They target certain channels at a cellular level to slow or break the abnormal rhythm. They often do nothing to fix or correct the problem. ...Read more
Depends on type.: Most of the time sinus tachycardia (ST) isn't a harmful condition, and therefore does not require treatment. Rather, the REASON for sinus tachycardia should be investigated - if it's something ominous, it should be treated. There are 4 classes of antiarrhythmics. For symptomatic ST that interrupts your life, low doses of Class II (beta-blockers) or Class IV (calcium channel blocker) antiarrhythmic ...Read more
What is the antiarrythmic drug of choice for paroxysmal Afib started before 1yr in 72yr male hypertensive with mild left ventricular hyper trophy ?
A-fib drugs: There are options for treating atrial fibrillation. 1) Use beta blockers &/or calcium blockers to control the heart rate, but this does not prevent a-fib episodes. 2) Anti-arrhythmic drugs vary in effectiveness and side effects: amiodarone, sotalol, flecainide, and dofetilide are used. 3) An ablation procedure is another strategy.

How does a phycisian decide which anti-arrhythmic drug is best for patients abnormal heart rhythm?
Therapeutic profile: The anti and proarrhythmic effects of bupivacaine have been studied (pubmed id 9605693). Similarly, the local anesthetic properties of class i arrhythmics (function through sodium channel blockade like local anesthetics) have been compared with Lidocaine and bupivacaine. Toxicity of bupivacaine must be understood in the context of complex cardiac effects. See pmid3408033 and tinyurl.Com/bjdzske. ...Read moreSee 1 more doctor answer
Mildly: They're not actually classified as anti-arrhythmic medications, but are often used for benign arrhythmias such as PSVT and PVCs. ...Read more
Is there any antihypertensive that doesn't cause impotence (ed) & have an antiarythmatic effect for a 32yrs old male?
ED and BP meds: Most anti-hypertensive medicines cause no erectile dysfunction (ed). The major class of drugs that cause ed are beta-blockers. If you are one of those agents, that may be reponsible for your ed. Types of BP meds that can treat some arrhytmias are calicum channle blockers, Diltiazem is one of them and beta blockers. You should see a urologist to see if there are other causes for ed other than meds. ...Read more
