What is the primary benefit of cardiac glycosides/cardiotonics?

The primary benefit of cardiac glycosides, also known as cardiotonics, lies in their ability to strengthen and slow the heartbeat. These medications are particularly useful in the treatment of heart conditions such as congestive heart failure and certain types of arrhythmias. By increasing the force of the heart's contractions, cardiac glycosides enhance cardiac output, which is the volume of blood the heart pumps. This is crucial for patients with weakened heart muscles, as it helps improve overall circulation and reduces symptoms related to heart failure, such as shortness of breath and fatigue.

Additionally, by slowing the heart rate, these medications can help restore a more regular rhythm and improve the heart's efficiency. This combined effect of strengthening and slowing the heartbeat allows the heart to work more effectively without becoming overly stressed, which is essential for maintaining the health and well-being of patients with cardiovascular issues.
