Autonomic atrial tachycardia is a kind of atrial tachycardia, which is divided into two types, acute and chronic, each with its own typical symptoms. When the patient’s ventricular rate is too high, or when there is a critical and serious illness, he or she should urgently seek medical treatment. Autonomic atrial tachycardia refers to atrial tachycardia caused by a moderate increase in the autoregulation of an ectopic pacing site in the atria and an increase in the frequency of excitation release, and includes two types, namely, acute autonomic atrial tachycardia and chronic autonomic atrial tachycardia. Acute spontaneous atrial tachycardia is mostly seen in adults, often with cardiomyopathy, pulmonary heart disease, chronic obstructive pulmonary disease, acute myocardial infarction and other underlying diseases, can be induced by digitalis overdose, hypokalemia, alcohol consumption, hypoxia and other triggers, with the characteristics of a sudden stop, the onset of the patient may have dizziness, palpitations, chest tightness and other symptoms. Chronic spontaneous atrial tachycardia is mostly seen in infants and young children, usually with family heredity, the onset of a longer period of time, but usually only mild chest tightness, palpitation symptoms, if also combined with organic heart disease, patients may have symptoms such as low blood pressure, fainting and other symptoms, as well as dilated cardiomyopathy, heart failure and other complications. If the patient’s heart rate is still good, no typical symptoms, usually do not need special treatment, if the ventricular rate of 140 beats / min or more, with signs of shock or severe congestive heart failure symptoms, as well as by digitalis intoxication triggered by the person should be urgent medical treatment, specific measures should be in accordance with the doctor’s instructions.
