The diagnosis of digoxin toxicity is based primarily on clinical suspicion and clinical features (including ECG changes) suggestive of digoxin intoxication, and can be confirmed by assessment of serum digoxin levels.
8 paź 2024 · The ECG features of digoxin effect are seen with therapeutic doses of digoxin and are due to: Shortening of the atrial and ventricular refractory periods — producing a short QT interval with secondary repolarisation abnormalities affecting the ST segments, T waves and U waves.
Digoxin ECG changes: arrhythmias, conduction defects and waveform changes. Digoxin may be used in patients with heart failure, atrial fibrillation, atrial flutter, and in selected cases of paroxysmal supraventricular tachycardia.
8 paź 2024 · Digoxin can cause a multitude of dysrhythmias due to: Increased automaticity (increased intracellular calcium) Decreased AV conduction (increased vagal effects at the AV node)
13 maj 2021 · mechanism of action of digoxin (1) Digoxin inhibits the cardiac Na/K antiporter (orange oval, above). This causes an increase in intracellular sodium and a decrease in intracellular potassium. The decrease in intracellular potassium is what causes hyperkalemia in patients with digoxin overdose.
