Which drug is used to manage abnormal heart rhythms?

Digoxin is a medication that is commonly used to manage certain types of abnormal heart rhythms, particularly atrial fibrillation and atrial flutter. It operates by increasing the force of heart contractions and helping to control the heart rate. This can be particularly beneficial for patients with these conditions, as it aids in regulating how efficiently the heart pumps blood. The effectiveness of digoxin in managing heart rhythms has made it a critical medication in the cardiology field.

Furosemide, on the other hand, is a diuretic mainly used to treat fluid retention and high blood pressure, rather than to directly address heart rhythm abnormalities. Cocaine is a stimulant that can actually induce abnormal heart rhythms and is not used therapeutically for this purpose. Temazepam is a medication primarily used to treat insomnia and does not have a role in the management of heart rhythm disorders. Each of these other drugs serves distinct purposes unrelated to the management of arrhythmias, further solidifying digoxin's unique role in treating abnormal heart rhythms.
