What is atrial fibrillation uptodate?
INTRODUCTION. Atrial fibrillation (AF) is the most commonly treated cardiac arrhythmia. (See “Epidemiology of and risk factors for atrial fibrillation”, section on ‘Epidemiology’.) AF is generally associated with an irregularly irregular ventricular rhythm and absence of distinct P waves.
When do you start rate control in AF?
Current guidelines define adequate rate control in atrial fibrillation as maintenance of the ventricular rate response between 60 and 80 beats/min at rest and between 90 and 115 beats/min during moderate exercise.
Which is better cardioversion or ablation?
Conclusion: In patients with AF, there is a small periprocedural stroke risk with ablation in comparison to cardioversion. However, over longer-term follow-up, ablation is associated with a slightly lower rate of stroke.
What causes AFib uptodate?
These include hypertension, coronary artery disease, heart failure, valvular heart disease, obesity [2], and sleep-apnea syndrome. It is well established that high levels of alcohol [3] can increase the probability of developing AF, and that hyperthyroidism can cause AF.
Why do you give metoprolol for atrial fibrillation?
Metoprolol. Also called Lopressor or Toprol XL, is a type of medicine called a beta blocker. There are many beta blockers but this is most commonly prescribed. It helps keep the heart from beating too fast, but it does not put the heart into a normal rhythm.
What is the safest beta-blocker for AFib?
Bisoprolol* or metoprolol succinate are first-choice beta-blockers for patients with atrial fibrillation as they are prescribed once-daily and do not require dose adjustment in patients with renal impairment. Bisoprolol is preferred as it is more cardioselective than metoprolol and may cause more bradycardia.
Which is safer metoprolol or dilTIAZem?
Conclusions: Diltiazem was more effective in achieving rate control in ED patients with AFF and did so with no increased incidence of adverse effects.
Who is not a candidate for cardiac ablation?
People who may not be ideal candidates for cardiac ablation for afib include: People whose heart has become very enlarged. Cardiac ablation is less effective when that’s the case. People who’ve had afib for a long time—it doesn’t work as well for those who’ve had it several months or longer.
Which is better for AFib metoprolol or dilTIAZem?
Conclusion: Intravenous diltiazem has higher efficacy, shorter average onset time, lower ventricular rate, less impact on blood pressure, and with no increase in adverse events compared to intravenous metoprolol.
Which is better digoxin or metoprolol?
Lanoxin (digoxin) is effective at treating heart failure symptoms, but it doesn’t lower your risk of death compared to other heart failure medicines. Lowers blood pressure and controls heart rate. Toprol XL (metoprolol succinate) is good for controlling chest pain, treating heart failure, and heart attack.
Which is better for AFIB metoprolol or diltiazem?
How much diltiazem should I take for AFIB?
In the treatment of atrial arrhythmias, diltiazem is considered an effective rate-control drug. The authors’ recommendation for patients with atrial fibrillation or supraventricular tachycardia is 120 mg every 12 h (66.6% of the experts) as the proper dose for reducing the heart rate.
How long does it take to recover from AFIB ablation?
You’ll spend a day or two in intensive care, and you may be in the hospital for up to a week. At first, you’ll feel very tired and have some chest pain. You can probably go back to work in about 3 months, but it may take 6 months to get back to normal. Catheter ablation is considered safe. But it can cause:
