Since the introduction of digitalis into therapy approximately 200 years ago, there have been continuing admonitions concerning its toxicity. Over 400 years ago, herbalists listed the plant as being poisonous. In fiction, the homicidal use of digitalis has appeared in the writings of Mary Webb, Dorothy Sayers and Agatha Christie What is digoxin toxicity Digoxin toxicity also known as digitalis toxicity can be a problem with digitalis therapy. It may occur when you take too much of digoxin at one time. Digoxin toxicity can also occur when levels of the drug build up for other reasons The incidence of digitalis toxicity has declined in recent years, due to decreased use of this drug along with improved technology for monitoring of drug levels and increased awareness of drug interactions. Nevertheless, cardiac glycoside toxicity continues to be a problem in the United States because of the wide use of digoxin (a preparation.. The visual aberrations caused by digitalis include a tipping of the color scale toward yellow (xanthopsia), and halos around bright points of light. Such effects are displayed in some of the later works of Vincent van Gogh, his yellow period. Halos around the stars and moon are evident in his famous painting The Starry Night and other works Digoxin toxicity, also known as digoxin poisoning, is a type of poisoning that occurs in people who take too much of the medication digoxin or eat plants such as foxglove that contain a similar substance. Symptoms are typically vague. They may include vomiting, loss of appetite, confusion, blurred vision, changes in color perception, and decreased energy. Potential complications include an irregular heartbeat, which can be either too fast or too slow. Toxicity may occur over a short period of t

Digitalis poisoning: historical and forensic aspect

  1. ECG Features of Digoxin Toxicity Digoxin can cause a multitude of dysrhythmias due to: increased automaticity (increased intracellular calcium) decreased AV conduction (increased vagal effects at the AV node
  2. Digitalis toxicity refers to the arrhythmias and conduction disturbances (as well as the toxic systemic effects described later) produced by this class of drug. Digitalis toxicity should not be confused with digitalis effect
  3. Digitalis Toxicity Digitalis is a type of drug that is used as a treatment for heart conditions. It has a narrow therapeutic range and if an individual takes an increased dose of this drug, he will suffer a condition known as digitalis toxicity and experience different untoward symptoms [1]

Digoxin is the most common formulation of digitalis, a cardiac glycoside used in the management of systolic heart failure and atrial arrhythmias. The use of medicinal plants containing cardiac glycosides dates back to the ancient Egyptians. Modern digitalis is derived from the foxglove plant and has been used for the last 200 years Biologic: A case in which digitalis in serum samples is detected, as determined by a commercial laboratory. Therapeutic levels of digoxin typically range from 0.5 to 2.0 ng/mL. (3-4) Multiple determinants exist for digoxin poisoning and serum digoxin concentrations overlap between symptomatic and asymptomatic patients

The ECG shows a few important features of digitalis intoxication: sinus node depression, AV junctional rhythm, and ventricular bigeminal rhythm arising in the fascicles of left bundle branch system. Narrow negative P waves suggest atrial activation starting centrally near the low interatrial septum Digitalis Toxicity occurs in individuals who intake excessive amounts of digoxin, a drug used to treat heart failure and heart rhythm issues, in a short period of time. Digitalis Toxicity may also develop in individuals who accumulate high levels of digoxin during the course of (chronic) treatmen Digitalis intoxication, known as digitalism, results from an overdose of digitalis and causes gastrointestinal disturbances and pain, severe headache, nausea, vomiting and diarrhoea, cardiac arrhythmias, as well as sometimes resulting in xanthopsia (jaundiced or yellow vision) Digoxin toxicity happens when you have too much digoxin in your body and it becomes harmful. Digoxin is a medicine that is used to treat heart failure or arrhythmias (abnormal heart rhythms). Digoxin toxicity can be life-threatening. What increases my risk for digoxin toxicity

Correlation between manifestations of digoxin toxicity and serum digoxin, calcium, potassium, and magnesium concentrations and arterial pH Cardiac toxicity accounts for about one-half, gastrointestinal disturbances for about one-fourth, and CNS and other toxicity for about one-fourth of these adverse events. Cardiovascular. Common (1% to 10%): Arrhythmia, conduction disturbances, bigeminy, trigeminy, PR prolongation, sinus bradycardia The widespread availability of Fab fragments of high-affinity, polyclonal, digoxin-specific antibodies provides the clinician with a means of rapidly and selectively reversing digitalis toxicity with little risk of adverse effects. 17 18 19 A number of patients have now been treated with antidigoxin Fab fragments on ≥2 occasions without incident Digitalis toxicity refers to the arrhythmias and conduction disturbances (as well as the toxic systemic effects described later) produced by this class of drug. Digitalis toxicity should not be confused with digitalis effect. Digitalis effect ( Figs. 18-1 and 18-2) refers to the distinct scooping (thumbprinting sign) of the ST-T complex. Digitalis toxicity (digitoxicity) Digitalis toxicity (digitoxicity) is quite uncommon nowadays compared to what it used to be earlier.

Digitalis toxicity. Digitalis is a medicine that is used to treat certain heart conditions. Digitalis toxicity can be a side effect of digitalis therapy. It may occur when you take too much of the drug at one time. It can also occur when levels of the drug build up for other reasons such as other medical problems you have Digitalis has a narrow therapeutic serum range, with toxicity occurring at levels that are dependent on individual response. Laboratory levels are evaluated in conjunction with clinical manifestations and ECG to determine individual therapeutic levels or resolution of toxicity Pharmacokinetics and toxicity. The long half-life of digitalis compounds necessitates special considerations when dosing.
