<prompt> Digoxin toxicity produce all of the changes in ECG exceptInveed T wavesProlonged QT intervalST depressionProlonged PR interval  <response>: In digoxin toxicity, the finding of frequent premature ventricular beats PVCs is the most common and the earliest dysrhythmia. Sinus bradycardia is also very common. In addition, depressed conduction is a predominant feature of digoxin toxicity. Other ECG changes that suggest digoxin toxicity include bigeminal and trigeminal rhythms, ventricular bigeminy, and bidirectional ventricular tachycardia. Refer kDT 7e p514
