As the patient population continues to age, the prevalence of this arrhythmia rises as well, from less than 0.05 percent in patients 25 to 35 years of age to more than 5 percent in patients over 69 years of age.2Atrial fibrillation is associated with significant morbidity, including an increased susceptibility to embolic stroke. According to the Framingham Heart Study,1 atrial fibrillation has a prevalence of 4 percent in the adult population. Atrial fibrillation is the most common sustained arrhythmia encountered in primary care practice. Until the results of several large-scale randomized clinical trials are available, the decision to choose cardioversion or maintenance of sinus rhythm must be individualized, based on relief of symptoms and reduction of the morbidity and mortality associated with atrial fibrillation. Other methods of pharmacologic and nonpharmacologic cardioversion remain under development. Several advances have been made in antiarrhythmic medications, including the development of ibutilide, a class III antiarrhythmic drug indicated for acute cardioversion of atrial fibrillation. Pharmacologic cardioversion, although less effective, offers an alternative to DC cardioversion. metoprolol 50 mg cost By Najm Haque, PGY2 Atrial fibrillation with rapid ventricular response is a common emergency room problem. Patient with stable blood pressure who present in Afib with RVR need medications to control their heart rate (unstable patients require more cardioversion). Traditionally, these patients receive beta blockers or calcium channel blockers in IV form for rate control. The most common medications used in the US are metoprolol and diltiazem, but it is unclear which is superior. Fromm et al This study was published in the Journal of Emergency Medicine in April 2015 and compared how fast rate control was achieved in diltiazem vs metoprolol. This was a prospective, double-blind study which compared the effects of both medications at 30 minutes, as well as looking at mean decrease in heart rate, and adverse effects. Patients were randomized and either received Diltiazem 0.25 mg/kg IVP (maximum dose of 30mg) or Metoprolol 0.15mg/kg IVP (maximum dose of 10mg).

She have been on Metoprolol 25 mg and Wafarin 2.5, but the medication became less. Metoprolol was used as a long-acting CR/XL formulation from AstraZeneca, sponsors of the study at an initial dose of 100 mg once daily, with a recommendation to increase to 200 mg once daily, or. Metoprolol succinate accounts for almost three-quarters of the beta-blockers dispensed in New Zealand. There is, however, little evidence to support the systematic use of metoprolol succinate over other medicines in this class. Prescribers are encouraged to use the pharmacological diversity of beta-blockers and the clinical characteristics of patients to individualise treatment and optimise care. It is likely that metoprolol succinate is the beta-blocker of choice among New Zealand prescribers because it has a wide range of indications, i.e. angina, arrhythmia, heart failure, hypertension and post-myocardial infarction, it is dosed once-daily and it is cardioselective (see below). The innovator brand (Betaloc) was also heavily marketed in New Zealand before alternative options, e.g. The recent disruption of the supply of metoprolol succinate where dispensing was limited to fortnightly or monthly amounts highlights the risk of depending on one beta-blocker. A review of the different properties of beta-blockers, their role in different cardiovascular conditions and co-morbidities is therefore timely. In atrial fibrillation (AFib), half of the heart’s four chambers aren’t beating properly, but are dancing around randomly without rhythm. This sounds scary and, in some ways, it’s astonishing that people with AFib can function well at all. But remember that the heart's upper chambers (the atria), which are malfunctioning in AFib, don’t pump blood to the body or through the lungs. They simply pass blood on to the muscular lower chambers of the heart (the ventricles) that do the hard work. People with AFib tend to do fine when they’re not exerting themselves. Without treatment for AFib’s fast heart rate, however, the ability to be physically active is greatly reduced and the heart muscle can be damaged over time. As with all of us, AFib patients benefit from consistent, moderate exercise.
