Amiodarone: Guidelines for Use and Monitoring - American

Amiodarone is a useful oral anti-arrhythmic in the long-term management of atrial fibrillation; this should be discussed with a cardiologist as the patient should be made aware of the risks surrounding long-term amiodarone therapy. Combination therapy for difficult rate-control (resting HR >110bpm in spite of maximal therapy with one agent You would normally start on a low dose of these and the increase them if you need to. This usually means starting diltiazem at a dose of either 120mg once a day or 90mg twice a day. With verapamil, the starting dose is 120mg once a day or a split dose of either 40mg twice or three times a day

This letter was shown to the authors who responded as follows: Sir,The main aim of our study was to prospectively examine the efficacy and safety of intravenous amiodarone in recent onset atrial fibrillation (AF).1-1 The study did not include patients with AF of more than 48 hours duration, and thus, we have not tried to directly imply any message about the efficacy of amiodarone conversion in. The importance of the current study is it used a lower [IV] dose and still there was over a 70% relative risk reduction in atrial fibrillation with amiodarone. That's huge, a dramatic improvement in the care of patients, he said. Amiodarone should be used routinely in this setting, he said Logistic regression was used to evaluate the impact of prophylactic amiodarone on incidence of new onset atrial fibrillation between the two groups. RESULTS: The incidence of AF was lower in patients who received amiodarone in the post operative period [12.7% vs. 29.3%, OR 0.35 (95% CI 0.15 - 0.83), p=0.018]

Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of irregular heartbeats. This includes ventricular tachycardia (VT), ventricular fibrillation (VF), and wide complex tachycardia, as well as atrial fibrillation and paroxysmal supraventricular tachycardia. Evidence in cardiac arrest, however, is poor. It can be given by mouth, intravenously, or intraosseously Atenolol oral 25mg twice daily and up-titrate to 50mg twice daily if ventricular rate is still >110bpm. In frail or elderly patients consider starting dose of atenolol oral 25mg once daily

PPT - A Practical Overview of Antiarrhythmic Drugs

Amiodarone for Atrial Fibrillation Cardioversion. Termination of recent-onset atrial fibrillation (AF) or flutter (AFl) can be accomplished either by chemical or electrical cardioversion in the ED. Chemical cardioversion is typically pursued with amiodarone. Meta-analyses have demonstrated an increased conversion rate for amiodarone versus placebo (Chevalier 2003, Letelier 2003) Oral amiodarone increases the efficacy of direct-current cardioversion in restoration of sinus rhythm in patients with chronic atrial fibrillation. Capucci A., Villani G. Q., Aschieri D., Rosi A. & Piepoli M. F. Eur Heart J, 2000. 21: 66-73 This review concluded that total amiodarone doses of 3,000 mg or higher may be more effective than lower doses in reducing the rate of post-operative atrial fibrillation after cardiac surgery. Pre-operative initiation of amiodarone appears to be unnecessary This was a prospective RCT comparing the use of magnesium vs. amiodarone among 42 ICU patients with atrial tachyarrhythmias (71% with AF or atrial flutter). Magnesium was provided as a bolus of 0.037 g/kg followed by an infusion of 0.025 g/kg/hr for 24 hours Conversion of recent-onset paroxysmal atrial fibrillation to normal sinus rhythm: the effect of no treatment and high-dose amiodarone — A randomized, placebo-controlled study.

—Low-dose amiodarone is effective for maintaining sinus rhythm in patients with difficult to treat chronic atrial fibrillation or flutter and is associated with a low incidence of serious side. On postoperative day 2 oral amiodarone was started with a dose of 600 mg/d for 5 days, 400 mg/d for the following 5 days, and 200 mg/d for 20 days, and 80 patients received placebo (control group) Using amiodarone for atrial fibrillation makes it less likely that the blood will pool in the heart's chambers and produce a clot. If a doctor determines that giving amiodarone for atrial fibrillation is the right treatment option, the dosage given is individualized to the patient Patients received either an intravenous loading dose of 300 mg of amiodarone or placebo in the operating room, followed by a perfusion of 15 mg. kg (-1). 24 h (-1) for 2 days. The primary endpoint was the development of atrial fibrillation occurring at any time within the postoperative period Introduction: Amiodarone is the most effective drug for the treatment of atrial fibrillation (AF), but long-term administration of standard doses can have prohibitive side effects. Little data is available for use of lower doses. We sought to determine the lowest effective dose for rhythm control in a single-physician practice

The typical maintenance dose of amiodarone is 200 mg per day Amiodarone toxicity is reviewed and summarized including pulmonary (lung) toxicity, thyroid toxicity and hepatic (liver) toxicity. Ocular toxicity and blue man syndrome are also discussed The aim of the present study was to assess the efficacy and safety of the pharmacological conversion of persistent atrial fibrillation (AF) using amiodarone or/and ibutilide.

The treatment protocol included a loading dose of 1200 mg intravenous amiodarone in 24 hours, after which amiodarone treatment was continued orally

UpToDat

Continuing Education Activity. Amiodarone is one of the most commonly used anti-arrhythmic drugs. While the United States FDA has labeled amiodarone for the treatment of life-threatening ventricular arrhythmias, the drug is commonly used off-label to treat supraventricular tachyarrhythmias such as atrial fibrillation as well as for the prevention of ventricular tachyarrhythmias (VTs) in high. Conclusions. Postoperative low-dose amiodarone given orally to patients who had cardiopulmonary bypass was well tolerated and appeared to reduce the incidence of new-onset AF and decrease the length of hospital stay. AB - Background. Atrial fibrillation (AF) is a common occurrence after heart operations that use cardiopulmonary bypass 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 the..

Atrial Fibrillation (AF) & Flutter complicating critical

Atrial fibrillation (also referred to as AFib or AF) is the most common type of abnormal heart rhythm.; Atrial fibrillation is caused by abnormal electrical discharges (signals) that generate chaotically throughout the upper chambers of the heart (atria).; It reduces the ability of the atria to pump blood into the ventricles, and usually causes the heart to beat too rapidly The newest medication, dronedarone (Multaq®), is an amiodarone-derivative that lacks the iodine that makes amiodarone toxic. It is slightly less effective than amiodarone, but without many of the side effects of amiodarone. It also has some beta-blocking properties for rate control

Anticoagulation: If the onset of atrial fibrillation is unknown, or the patient is in permanent atrial fibrillation, the risk of stroke after cardioversion is increased. In the unstable patient, a rapid attempt at cardioversion is still warranted, but starting heparin as soon as possible afterwards is a good idea Abstract Background: To evaluate whether postoperative administration of intravenous low‐dose amiodarone and magnesium sulfate (MgSO4) combination would reduce the incidence of atrial fibrillation following coronary artery bypass grafting (CABG) in normomagnesemic high‐risk patients for postoperative atrial fibrillation (POAF). Methods: A total of 136 patients undergoing elective CABG and. The Canadian Trial of Atrial Fibrillation (CTAF) utilized a dosage regimen of 10 mg/kg PO once daily for 2 weeks, followed by 300 mg once daily for 4 weeks, followed by a maintenance dose of 200 mg PO once daily.
