8 paź 2024 · Digoxin effect refers to the presence on the ECG of: Downsloping ST depression with a characteristic “reverse tick” or “Salvador Dali sagging” appearance; Flattened, inverted, or biphasic T waves; Shortened QT interval
OVERVIEW. 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. Chronic digoxin toxicity varies in severity ...
8 sie 2024 · Digoxin toxicity is a clinical diagnosis that relies in part on ECG findings such as signs of increased automaticity and atrioventricular node blockade (premature ventricular contractions, slowed ventricular response), but also on clinical features, history of digoxin intake, history of other illnesses, and elevated digoxin concentrations.
Chronic digoxin toxic patients likely have hyperkalemia from renal failure, and calcium administration is likely safe in these patients; Acutely toxic patients will not benefit from calcium, and priority must be placed on administering DigiFab; Hypokalemia. Chronic intoxication Raise level to 3.5-4; Acute intoxication
4 mar 2023 · Digoxin exhibits its therapeutic and toxic effects by poisoning the sodium-potassium ATPase. The subsequent increase in intracellular sodium leads to increased intracellular calcium by decreasing calcium expulsion through the sodium-calcium cation exchanger.
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.
