In all patients with AF, regardless of concomitant HF, digoxin use was associated with an increased risk of sudden cardiac death (SCD) (HR 1

Geri: Older adults are at increased risk for toxic effects of digoxin (appears on Beers list) due to age-related decreased renal clearance, which can exist even when serum creatinine levels are normal
Study with Quizlet and memorize flashcards containing terms like The nurse is preparing to administer digoxin (Lanoxin) 0

Digoxin immune Fab (Digibind) Rationale: Digibind binds and removes digoxin from the body and prevents toxic effects of digoxin overdose
Oral digoxin and a placebo was used in 25 outpatients, it was determined Recent studies have discussed the role of digoxin as a management therapy rather than justfor acute treatment of heart failure

The following principles should be viewed as a general guide to the use of digoxin for its inotropic or electrophysiologic effects, which must be modified according
lack of feeling or emotion
Typically, digoxin levels are considered therapeutic for heart rate control between 0
In suspected toxicity or ineffectiveness, digoxin levels should be monitored
What would the nurse expect to find when evaluating for the therapeutic effectiveness of this drug? Diaphoresis with decreased urinary output Increased heart rate with increase respirations Improved respiratory status & increase urinary output Decreased chest pain & decreased blood
Although plants in the foxglove The RATE-AF trial, published in 2020, demonstrated the effectiveness of low dose digoxin for atrial fibrillation
In the early 20th century, James McKenzie and Thomas Lewis established the role of digitalis as the cornerstone of treatment for chronic Atrial Fibrillation (AF) [], and for over 50 years it has played an important role as a therapeutic agent for
Central nervous system effects, such as weakness, dizziness, confusion, apathy, malaise, headache, depression, and psychosis
Digoxin toxicity—confusion, loss of appetite, nausea, vomiting, diarrhea, change in vision such as blurry or yellow vision, fatigue, fast or irregular heartbeat
To evaluate a therapeutic effectiveness of this medication, the nurse would expect which of the following changes in the client's vital signs? a BP 85/50 mm Hg, pulse 60 bpm, respirations 26 cm b
(2) Vagomimetic effect: Digoxin at therapeutic doses increases vagal tone (ie, decreases sinoatrial and atrioventricular conduction)
Digoxin has many interactions, including: Erythromycin and tetracycline (antibiotics) Antiarrhythmic drugs (amiodarone) Calcium channel blockers
Digoxin and diuretics were once the cornerstones of therapy for patients with chronic heart failure
