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.
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]
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
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]
Cardiac glycosides have long served as the main medical treatment to congestive heart failure and cardiac arrhythmia, due to their effects of increasing the force of muscle contraction while reducing heart rate. Heart failure is characterized by an inability to pump enough blood to support the body, possibly due to a decrease in the volume of ...
Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate.. Chronotropic drugs may change the heart rate and rhythm by affecting the electrical conduction system of the heart and the nerves that influence it, such as by changing the rhythm produced by the sinoatrial node.
This reduces heart rate and vascular resistance. [9] Digoxin increases vagal tone from the vasomotor centre, which decreases pulse. [7] G-series nerve agents have their most potent effect in the vasomotor center. [10]
