These changes commonly involve the T wave and include flattening, inversion, scooped appearance of ST-segment and ST
In digoxin toxicity, the finding of frequent premature ventricular beats (PVCs) is the most

Acute digoxin poisoning manifests with vomiting, hyperkalaemia and brady-tachyarrhythmias potentially leading to death, whereas chronic digoxin toxicity is far

The ST segment yields important information because it represents the end of ventricular repolarization
In the digitalis effect, the ST segments are often likened to a ‘reverse tick’ or to the shape of Dali’s moustache (see figure 2)

Those signs can occur with a therapeutic digoxin concentration and are not necessarily indicative of digoxin-related toxic effects
These changes are referred to as the digitalis effect, which must be distinguished from digitalis toxicity (which manifests primarily as cardiac dysrhythmia)
However, there are several non-ischemic conditions that can produce depression of the ST-segment
Acute digitalis toxicity can result from unintentional, suicidal, or homicidal overdose of the digitalis preparation digoxin, or accidental ingestion of plants that contain cardiac glycosides
The ST segment depression is a known phenomenon of digoxin effect as well as toxicity but sometimes these changes can be really confusing during inter… Digoxin effects on the baseline ECG include downward scooping of the ST segment and inverted T waves
Acute digitalis toxicity can result from unintentional, suicidal, or homicidal overdose of the digitalis preparation digoxin, or accidental ingestion of plants that contain cardiac glycosides
The combination of features that favor digoxin toxicity include atrial fibrillation, narrow complex QRS interval, and a “scooped” morphology of the ST-segments
