Arrhythmias (Heart Rhythm Disturbances) and Digoxin

Read more about Digoxin.

Overview

Digoxin, also known as Lanoxin, contains digitalis glycosides from the foxglove plant, Digitalis lanaxa. Digitalis glycosides have a very narrow therapeutic window between taking too little and taking too much. These drugs are very effective at treating heart failure, but have much more restricted use in heart rhythm disturbances.

Effect of Digoxin on Arrhythmias (Heart Rhythm Disturbances)

These drugs are primarily used to control the rate of ventricular response to tachyarrhythmias (heartbeats that are too fast).
