Digoxin may be prescribed for a child to treat heart defects. Possible side effects in children are: dysrhythmia, nausea, vomiting, a slower-than-normal heart rate and anorexia. [4] Children may demonstrate side effects if they are breastfed. Digoxin is also absorbed by the infant in utero. [5]
For heart rate control (atrial fibrillation), plasma levels are less defined and are generally titrated to a goal heart rate. Typically, digoxin levels are considered therapeutic for heart rate control between 0.5 and 2.0 ng/mL (or 0.6 and 2.6 nmol/L). [37] In suspected toxicity or ineffectiveness, digoxin levels should be monitored.
The level of digoxin for treatment is typically 0.5-2 ng/mL. [8] Since this is a narrow therapeutic index, digoxin overdose can happen. A serum digoxin concentration of 0.5-0.9 ng/mL among those with heart failure is associated with reduced heart failure deaths and hospitalizations. [9]
According to the ACC/AHA guidelines, intravenous digoxin (cardiac glycoside) can be used in atrial fibrillation (Afib) to assist heartbeats. [90] In multicenter randomised controlled trials, intravenous digoxin was shown to be effective in controlling the heart rate compared to a placebo. [91] [92]
A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
They act by blocking the effects of catecholamines at the β 1-adrenergic receptors, thereby decreasing sympathetic activity on the heart, which reduces intracellular cAMP levels and hence reduces Ca 2+ influx. These agents are particularly useful in the treatment of supraventricular tachycardias. They decrease conduction through the AV node.
Proarrhythmia is a new or more frequent occurrence of pre-existing arrhythmias, paradoxically precipitated by antiarrhythmic therapy, which means it is a side effect associated with the administration of some existing antiarrhythmic drugs, as well as drugs for other indications. In other words, it is a tendency of antiarrhythmic drugs to ...
Digitoxin is a cardiac glycoside used for the treatment of heart failure and certain kinds of heart arrhythmia. It is a phytosteroid and is similar in structure and effects to digoxin, though the effects are longer-lasting. Unlike digoxin, which is eliminated from the body via the kidneys, it is eliminated via the liver, and so can be used in ...
