Class IV antiarrhythmics are a group of medications primarily used to treat cardiac arrhythmias by inhibiting calcium channels in the heart. They slow down the conduction through the atrioventricular (AV) node and reduce heart rate, which can help manage various types of arrhythmias. These drugs are especially useful in controlling ventricular rates in conditions like atrial fibrillation and atrial flutter, making them significant in the context of managing heart rhythm disorders.
