Digoxin is a cardiac glycoside medication used for systolic heart failure and arrhythmias such as atrial fibrillation. Digoxin toxicity can cause ECG changes and arrhythmias.
•Digoxin Effects on the ECG:
•Diffuse ST segment scooping and depression.
•Flattening of the T wave or biphasic T wave.
•Atrioventricular (AV) blocks (1st, 2nd or 3rd degree).
•Regular junctional rhythm in the setting of atrial fibrillation (3rd degree AV block with a junctional escape rhythm).
•Almost any arrhythmia.
