The beta-blocking effects of atenolol, as measured by reduction of exercise-related tachycardia, are apparent within 1 hour and are maximal within 2 to 4 hours following a single oral dose. [4] The general effects of atenolol, including beta-blocking and antihypertensive effects, last for at least 24 hours following oral doses of 50 or 100 mg ...
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
Prevent paroxysmal atrial fibrillation [7] and haemodynamically stable ventricular tachycardia [8] (amiodarone) Treat atrial flutter and atrial fibrillation (ibutilide) Treat ventricular tachycardia and atrial fibrillation (sotalol) Treat Wolff-Parkinson-White syndrome; IV Calcium channel blockers Diltiazem; Verapamil; Ca 2+ channel blocker
Sotalol is indicated for the treatment of atrial or ventricular tachyarrhythmias, and AV re-entrant arrhythmias. Ibutilide is the only antiarrhythmic agent currently approved by the Food and Drug Administration for acute conversion of atrial fibrillation to sinus rhythm.

Nadolol is used to treat hypertension and for long-term treatment of angina pectoris and is approved by the FDA for these purposes. [8]It is regularly used off-label [8] for control of heart rate in people with atrial fibrillation, [9] prevention of migraine headaches; [10] prevention of bleeding veins in people with portal hypertension caused by cirrhosis; [4] and to treat people with high ...
The negative chronotropic effects of CCBs make them a commonly used class of agents in individuals with atrial fibrillation or flutter in whom control of the heart rate is generally a goal. Negative chronotropy can be beneficial when treating a variety of disease processes because lower heart rates represent lower cardiac oxygen requirements.
Premature atrial contractions (PACs) are common in the general population, and increase with age. [5] Over 99% of individuals in the general population will have at least one PAC in a 24 hour period. [6] Many PACs can indicate increased risk of atrial fibrillation and/or ischemic stroke. [6]
