What are the signs of digoxin toxicity?

Digoxin toxicity is characterized by a specific set of symptoms due to the drug's effects on the cardiovascular system and its ability to alter electrolyte balance. The manifestations include visual disturbances such as blurred vision, yellow or green halos around lights, and other color vision changes. Gastrointestinal symptoms like nausea and vomiting are also prominent because the drug can irritate the stomach lining. Bradycardia, or a slowed heart rate, is particularly concerning as digoxin affects cardiac conduction, potentially leading to arrhythmias. Recognizing these signs is crucial for timely intervention and management of toxicity, making the symptoms in the first option the hallmark indicators of digoxin overdose.
