This is depicted below, followed by full 12-lead ECG examples of digoxin toxicity, atrial tachycardia with 2:1 block and bidirectional ventricular tachycardia.

Digitalis toxicity (DT) occurs when you take too much ... an electrocardiogram (ECG) to test for abnormal heartbeats a blood chemistry test to examine your metabolism a blood test for digitalis ...

Digoxin, originally derived from the foxglove flower, blocks the sodium/potassium ATPase pump. The mechanism by which this decreases atrioventricular (AV) conduction is not clear, butperhaps it is ...

ECG results showed sinus bradycardia, frequent premature ventricular complexes, and scooped ST segments consistent with cardenolide toxicity. A serum digoxin assay showed a level of 0.5 ng/L ...
