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.

Learn how digoxin affects cardiac function and ECG, and what arrhythmias and conduction defects it may cause. Find out how to recognize digoxin ECG changes and how to treat digoxin overdose.
8 paź 2024 · ECG Features of Digoxin Toxicity. The classic digoxin toxic dysrhythmia combines: Supraventricular tachycardia (due to increased automaticity) Slow ventricular response (due to decreased AV conduction) Other common dysrhythmias associated with digoxin toxicity include:
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.
Digoxin toxicity is characterised by gastrointestinal distress, hyperkalemia and life-threatening dysryhthmias, including increased automaticity and AV nodal blockade; Digoxin has a narrow therapeutic index and chronic toxicity is more likely in the elderly and those with renal impairment
19 maj 2024 · Digoxin generates variations in the electrocardiogram at therapeutic doses, the best known being the "reverse tick sign",although it also causes T wave changes, shortening of the QT interval and prolongation of the PR interval.
20 paź 2022 · The incidence of digoxin excess and toxicity, along with the potential associated arrhythmias, are presented here. The management of digoxin intoxication, including the treatment of cardiac arrhythmias associated with digoxin toxicity, is discussed separately.
