Digoxin action

### Cardiac glycoside slows and strengthens heart rate

## Step1: Understanding Digoxin### Digoxin is a type of medication known as a cardiac glycoside. It is used to treat heart conditions such as atrial fibrillation and heart failure.## Step2: Mechanism of Action### Digoxin works by increasing the amount of calcium in the heart cells, which strengthens the heart's contraction and slows down the heart rate.## Step3: Resulting Effect### The combined effect of increased contraction strength and a slower heart rate is that the heart pumps more efficiently, which can be critical in conditions where the heart is not functioning properly.
