Digoxin poisoning will not resolve itself without resuscitation. Clinically, digoxin belongs to the digitalis class of cardiotonic drugs, mainly through direct action on the myocardium and vascular smooth muscle, and indirect action on the vagus nerve, thus increasing the contractility of the myocardium, reducing the heart rate and atrioventricular node conduction rate; clinically, it is mainly used for heart failure, accompanied by rapid ventricular rate of atrial fibrillation treatment. If poisoning occurs after digoxin use, anorexia, nausea, vomiting, atrioventricular block, cardiac arrest, atrioventricular tachycardia with conduction block, and other discomforts may occur at this time; they usually do not resolve spontaneously without treatment. After digoxin poisoning, digoxin should be discontinued immediately, and electrolytes should be monitored; if there is low potassium, potassium should be replenished immediately, and phenytoin sodium treatment is preferred when potassium is normal; if phenytoin sodium treatment is ineffective, amiodarone treatment can be taken, but the use of electrical resuscitation is prohibited to avoid the occurrence of ventricular fibrillation. If there is poisoning after using digitalis, it is recommended to consult a doctor for symptomatic treatment under the guidance of a doctor.
