What medication is commonly used to treat atrial fibrillation?

Cardizem, also known as diltiazem, is a calcium channel blocker that is frequently used to manage atrial fibrillation. It works by slowing down the heart rate and helping to control the rhythm by inhibiting the influx of calcium into the heart muscle cells. This action can contribute to the relaxation of the heart and improve cardiac function, making it an effective choice in the treatment of atrial fibrillation, particularly for rate control.

In atrial fibrillation, the heart's electrical signals become disorganized, leading to an irregular and often rapid heart rate. Medications like Cardizem help to stabilize the heart rate and improve overall rhythm management. Therefore, its usage aligns well with the goals of effectively controlling atrial fibrillation symptoms and enhancing patient outcomes.
