What is a common finding on an EKG in a patient with digoxin toxicity?

• A. Normal EKG
• B. ST segment elevation
• C. Bradycardia
• D. Widened QRS complex

Answer: (C)

In patients experiencing digoxin toxicity, bradycardia is indeed a common EKG finding. Digoxin, a medication used to treat heart conditions like atrial fibrillation and heart failure, can influence heart rate by enhancing vagal tone and inhibiting the conduction through the atrioventricular (AV) node. This results in a slower heart rate, characterized by bradycardia on an EKG.

When digoxin toxicity occurs, it can also lead to other arrhythmias, but bradycardia is one of the most direct results of its action on the heart. The changes in heart rhythm due to digoxin toxicity can manifest as a reduction in the heart rate, making bradycardia a hallmark finding when examining EKG traces of affected patients.

Understanding this effect of digoxin is critical for healthcare providers, as it has implications for patient management and potential interventions that may need to be undertaken in cases of toxicity.
