Short paroxysms of atrial tachycardia are defined as at least three adjacent atrial precontractions on the ECG. Most patients in this condition will have frequent atrial premature beats, and patients with short paroxysms of atrial tachycardia that can be clearly seen on the dynamic ECG need to improve the dynamic ECG, cardiac ultrasound and other examinations to clarify the causes of atrial tachycardia, such as coronary heart disease, heart failure, congenital heart disease, rheumatic heart disease and other diseases can Atrial tachycardia can be caused by coronary heart disease, heart failure, congenital heart disease, rheumatic heart disease, etc. Some patients have atrial tachycardia without a clear cause, which is idiopathic and may be caused by excessive stress and strain, smoking, etc. It is recommended that the cause be clearly identified before treatment, and medications such as metoprolol can be chosen to prevent and reduce the occurrence of atrial tachycardia and atrial presystole.
