Electrocardiographic Features of Digoxin Toxicity
 • Virtually any arrhythmia is possible. None specific for digoxin toxicity
 • Classic arrhythmias thought to be associated combine some SVT (↑ ectopy and automaticity) with slow ventricular rate (↓ AV conduction)
"Digitalis effect"
 • Shortening of QT interval
 • "Scooped" or "sagging" ST depressions
 • J point depression
 • Flattened/inverted/Biphasic T waves
