How are antiarrhythmic drugs classified?
Class I agents block sodium channels. Class II agents are Beta blockers. Class III agents prolong the cardiac action potential. Class IV agents are calcium channel blockers.
What is the most toxic antiarrhythmic agent?
In terms of its toxicity, amiodarone remains the most feared of the antiarrhythmic agents.
Which beta blocker is best for tachycardia?
Arrhythmias: bisoprolol and metoprolol succinate are often preferred. Beta-blockers are the first-line treatment for long-term symptomatic rate control in patients with a range of cardiac arrhythmias, including atrial fibrillation and ventricular tachycardia.
What are Class 3 antiarrhythmics used for?
A class III antiarrhythmic agent used to correct atrial fibrillation and atrial flutter, which can be considered as an alternative to cardioversion. A class III antiarrhythmic indicated for the treatment of recurrent hemodynamically unstable ventricular tachycardia and recurrent ventricular fibrillation.
What is a Class III drug?
Schedule III Schedule III drugs, substances, or chemicals are defined as drugs with a moderate to low potential for physical and psychological dependence. Schedule III drugs abuse potential is less than Schedule I and Schedule II drugs but more than Schedule IV.

These medications help treat arrhythmias such as ventricular fibrillation, ventricular tachycardia and atrial fibrillation. There are several types of antiarrhythmic agents, including beta blockers and ion channel blockers.
What are the side effects of antiarrhythmic drugs?

Is amiodarone an ideal antiarrhythmic drug?
Amiodarone is predominately a class III antiarrhythmic, but also possesses class I, II, and IV effects. By 1977 it was described as the ideal antiarrhythmic agent. However, clinicians underestimated potential difficulties caused by misunderstanding its variable absorption, slow initial response at nonloading dosages, and extended half-life.
