Acute digoxin poisoning manifests with vomiting, hyperkalaemia and brady-tachyarrhythmias potentially leading to death, whereas chronic digoxin toxicity is far more insidious, still with gastrointestinal symptoms but in addition bradycardia and automaticity on the ECG
1) some uncommon arrhythmias may particularly suggest the possibility of digoxin toxicity
1 shows a baseline sinus rhythm with a heart rate of 60 beats per minute (bpm)
The diagnosis of digoxin toxicity is based primarily on clinical suspicion and clinical features (including ECG changes) suggestive of digoxin intoxication, and can be
Digoxin toxicity Background Cardioactive glycoside, a subset of cardioactive steroids, that comes from the foxglove plant, Digitalis lanata Mechanism of Action Inhibits Na+/K+

Abnormalities in the baseline ECG of patients receiving digoxin therapy will be the substrate for further alterations and should be considered when evaluating chronic digoxin
Studies in patients with possible digitalis toxicity include the following: Serum digoxin level
Digoxin is a medication used to manage and treat heart failure and certain arrhythmias, and abortion
Increased intracellular calcium increases automaticity, and atrioventricular blockade increase vagal tone
Serum digoxin measurements can be of value in assessing potential toxicity in cases where digoxin intoxication is suspected but clinical or ECG signs of toxicity are absent
ST depression (reverse tick appearance) tachycardias (flutter with block, VT, VF) bradycardia -> complete heart block
Digoxin toxicity can occur even when the serum digoxin concentration is within the therapeutic range (between 0
This group typically has multiple co-morbidities and take multiple cardiovascular Digoxin is a chemical derived from the plant Digitalis purpurea, more commonly known as foxglove, and belongs to the class of medicines known as cardiac glycosides [1]
It can also occur when levels of the drug build up for other reasons such as other medical problems you have
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
Digoxin toxicity has produced a total AV Digoxin toxicity

ECG manifestations of digoxin toxicity, such as premature ventricular contractions, are numerous but, unfortunately, too nonspecific in most instances to be diagnostic
Almost any type of arrhythmia can occur in digoxin toxicity except Mobitz type II second degree AV block and atrial Case 1: A 45-year-old man in sinus rhythm, with an ejection fraction of 20%, normal coronaries, and normal renal function is receiving captopril 50 mg 3 times daily, carvedilol 25 mg and furosemide 40 mg twice daily, and spironolactone 25 mg daily
