Amiodarone is a class III antiarrhythmic (potassium channel blocker), which decreases SA and AV node conduction. It is also a notable inhibitor of the cytochrome P450 complex. It is indicated for supraventricular tachycardias in the context of heart failure as well as ventricular tachycardias after CPR, defibrillation, and epinephrine are ...

Amiodarone increases refractoriness and has a long half-life. It is indicated for refractory life-threatening ventricular arrhythmias, and is the first line treatment for patients not responding to CPR. Amiodarone is unique, as it has class I, II, III, IV antiarrhythmic effects because it alters the lipid membrane.

Amiodarone is a class III antiarrhythmic drug used to treat ventricular arrhythmias, specifically ventricular fibrillation and ventricular tachycardia. Amiodarone is most commonly used...

2020年3月13日 · Amiodarone is a class III antiarrhythmic medication that is commonly used for the treatment of atrial arrhythmias and ventricular arrhythmias (VAs) [1]. It is an effective antiarrhythmic medication, but long-term therapy can result in a wide variety of side effects affecting several organ systems, some of which can be life threatening [2].

Amiodarone is a class III antiarrhythmic (potassium channel blocker), which decreases SA and AV node conduction. It is also a notable inhibitor of the cytochrome P450 complex.

1999年11月4日 · In this article, we review the electrophysiologic effects of amiodarone based on previous reports and our own experiments in single cells and multicellular tissue preparations of mammalian hearts. The major interest is focused on the differences between acute and chronic effects of this compound.

Amiodarone increases refractoriness and has a long half-life. It is indicated for refractory life-threatening ventricular arrhythmias, and is the first line treatment for patients not responding to CPR. Amiodarone is unique, as it has class I, II, III, IV antiarrhythmic effects because it alters the lipid membrane.

2020年10月28日 · Class 3 antidysrhythmic medications - potassium channel blockers (amiodarone) Amiodarone (Nextrone, Pacerone) is a potassium channel blocker used to treat and prevent certain types of serious, life-threatening ventricular arrhythmias. Amiodarone is in a class of medications called antiarrhythmics and works by relaxing overactive heart muscles.
