Atrial rhythm

Introduction Atrial arrhythmia includes: atrial escape or atrial escape rhythm, atrial premature contraction (atrial early), atrial tachycardia (atrial tachycardia), atrial flutter (atrial flutter), atrial fibrillation (room) Trembling).

Cause

Short-term episodes of atrial fibrillation can be seen in patients with no structural heart disease. The authors continue to have organic heart disease, such as mitral valve disease, ischemic heart disease, hypertensive heart disease, cardiomyopathy, and also in the room. Septal defect, pulmonary infarction, tricuspid valve disease, and chronic heart failure. Also seen in patients with chronic pericarditis, hyperthyroidism, sick sinus, pre-excitation syndrome, and after cardiothoracic surgery, acute infection, hypothermia, electric shock or lightning strike. Some patients have no clear cause of solitary atrial fibrillation.

Atrial flutter patients are often accompanied by a variety of organic heart disease, such as hypertensive heart disease, coronary atherosclerotic heart disease, cardiomyopathy, congenital heart disease or cardiac surgery, caused by various heart diseases Increased atrial pressure, atrial enlargement, prolonged intraventricular conduction, cardiac autonomic dysfunction, and increased atrial premature beats are important causes or incentives for atrial flutter in these patients. With the increase in the treatment of various organic heart diseases and the improvement of its curative effect, the life expectancy of patients with structural heart disease is prolonged, and the incidence of atrial flutter will gradually increase.

According to the clinical symptoms and signs can be initially diagnosed, but the diagnosis requires an electrocardiogram.

Differential diagnosis

When the atrial tachycardia occurs, the room rate is about 160-220 beats/min.

When the atrial flutter occurs, the room rate is about 220-350 beats/min.

When the impure flutter occurs, the room rate is about 350-450 beats/min.

The rate of atrial fibrillation is about 450 to 600 beats per minute.
